Performance Tuning Jobs

The audio on my Dell laptop has stopped working completely. Windows shows on the volume meter, yet nothing is heard from the built-in speakers, headphones, or any external device I plug in. I have already run the standard Windows sound troubleshooters and double-checked the playback settings with no success. I’d like a technician who can connect remotely via AnyDesk, TeamViewer, or a similar tool, inspect drivers, BIOS settings, services, and hardware toggles, and then either restore full sound output or pinpoint the exact hardware fault so I know what part to replace. Deliverables • Live remote session that tests and repairs drivers, services, and BIOS/firmware-related audio settings • Confirmation that sound plays through both the laptop speakers and a connected h...

I have a desktop application written entirely in Python that is misbehaving, and I need another set of eyes on the code. The core logic is already in place, but certain functions crash unpredictably and performance has taken a hit since the last update. Your task: • Identify and isolate the root causes of the current errors. • Patch the bugs without breaking existing features. • Clean up any obvious performance bottlenecks you find along the way. • Provide a concise report outlining the fixes and any recommendations for future refactoring. The project is strictly about debugging—no new features required—so I expect focused, well-documented commits and clear communication as you work through each issue. If you are comfortable stepping through Python c...

I have a working Python web-scraping script that pulls data quickly but bogs down the moment it writes results into my MySQL database. The goal of this upgrade is simple: boost overall run-time by eliminating the storage bottleneck. Here is the current picture: • Language & stack: Python 3.x, standard scraping libraries (requests / BeautifulSoup) feeding a MySQL table. • Pain point: data storage is noticeably slower than retrieval or in-memory processing, turning otherwise fast runs into long waits. • Objective: increase speed—specifically by reworking the way data is written, buffered, or indexed so writes no longer throttle the workflow. What I need from you: 1. Analyse the existing write logic and pinpoint why inserts are slow (inefficient queries, lack of bul...

I need a reliable hand for just four hours each week to keep our online presence running smoothly. The first priority is our Linux VPS: you will schedule and verify regular backups, watch security logs and firewalls, and tune performance so pages stay fast even during traffic spikes. While you are in the server, you will also handle day-to-day website care. That means posting fresh content when I supply it, squashing any bugs that users report, and tightening site security patches as they appear. If an advert or banner needs to go live, you will drop it in and test the links. The final slice of the role is light digital marketing. Think quick social posts, scheduling promos, and launching or pausing ads that I prepare. Clear weekly reports—backup status, uptime, tasks completed, an...

SRE / DevOps Engineer We’ve built a real-time marketplace. Speed and reliability matter more than anything. We’re live. Things move fast. We need someone who can take ownership of infrastructure and make it solid.

I run a cluster of more than five WordPress sites on DigitalOcean and need someone who can step in as my go-to technical partner. The work is ongoing and will be billed on a monthly maintenance basis, so consistency and reliability matter just as much as raw skills. Each month you’ll make sure everything runs smoothly: applying core, theme, and plugin updates, tightening security, keeping performance on point, and making sure off-site and on-server backups are intact and restorable. The stack is flexible—I’m open to cPanel, Plesk, or working without a panel if that keeps the servers lean—so feel free to recommend whichever setup you believe will serve long-term stability and speed. I’m currently on DigitalOcean droplets and may expand, so your advice on scal...

We are looking for a part-time developer to improve and maintain an AI-based recruitment platform. The system is already built and fully functional, including CV analysis (Arabic & English), AI-based candidate insights, a virtual interview module, and PDF report generation. No new features are required at this stage. The main tasks are to fix existing bugs, improve system performance, enhance the accuracy of CV analysis (especially for Arabic CVs), clean and structure the output data, and refine the overall user experience. The developer should have strong experience in Python (Flask or FastAPI), API integration, and system optimisation. Experience with AI systems or CV parsing is preferred. This is a part-time role focused on stabilisation, accuracy improvement, and preparing the s...

I’m facing persistent outbound packet loss on my Linux server. The problem appeared a few days ago, right after I upgraded my hosting plan, and it has started to affect production-level traffic. Latency is acceptable and inbound packets arrive cleanly; only the outbound stream is dropping frames. I need someone who can jump in immediately, trace the root cause, and apply a permanent fix. Typical tools for the job might include tcpdump, traceroute, iptables, nftables, netstat, or any monitoring utilities you prefer—as long as the solution is clearly explained and reproducible. Acceptance criteria: • Outbound traffic shows 0 % (or normal-range) packet loss under load tests. • A short summary of what was wrong and the exact commands or configuration changes you app...

I’m ready to move our on-premise NAV 2017 environment into Microsoft Dynamics 365 Business Center so the team can start benefiting from the newest features, especially the advanced analytics and AI-powered insights that simply aren’t available in our current setup. Here’s what I need from you: • A full, verified migration of all financial records along with complete vendor information. • Lift-and-shift (or re-engineering where required) of every customization we rely on today, ensuring identical or better functionality once we are live in the cloud. • Configuration of Business Center to surface its modern analytics capabilities and any other native enhancements that will speed up reporting and decision-making. • Post-migration sanity checks...

I need a brand-new Azure virtual machine provisioned to the following spec: 6 vCPUs, 16 GB RAM and a 512 GB SSD or premium HDD. It must run Windows Server and come fully configured with SQL Server 2019, including Reporting Services. Please handle everything from resource group creation and networking through to SQL post-installation tweaks (enabling mixed authentication, applying the latest cumulative update, setting up a basic maintenance plan and opening only the necessary ports in the NSG). Once it’s ready, send me the connection details and an ARM template or step-by-step document so I can reproduce the deployment in the future. Deliverables: • Deployed Azure VM that meets the hardware specs • SQL Server 2019 with Reporting Services enabled and tested •...

My Android app is fully built and every asset is packed and ready. What I now need is a reliable developer who can take it across the finish line by publishing it on Google Play for me and then keeping it healthy with regular maintenance. Here’s the rhythm I’m aiming for: once the app is live, I’d like a maintenance release roughly every month. These updates will focus on the usual upkeep—bug fixes, performance tuning, and any minor tweaks needed to keep users happy on the latest Android versions. I’ll supply source code, artwork, copy, signing keys, and release notes; you handle the build, upload, and rollout through the Play Console, plus any follow-up configuration that Google requires. To make expectations crystal-clear, the initial milestone is the succ...

I run a Linux VPS on Bluehost that powers a handful of PHP web applications backed by MySQL. I’m ready to hand off the day-to-day technical work so I can focus on the product, but I need everything kept running smoothly right away. You’ll receive full Control Panel access (no root SSH), and from there I expect three core services: • Server maintenance – keep the OS, Apache, PHP versions and security patches up to date, monitor logs and resource usage, and restart services if they stall. • Database management – schedule automated MySQL backups, tune indexes for performance, and restore data quickly if ever required. • Code deployment – pull the latest code from the Git repository, run any composer / npm steps, update environment variables, ...

I run a WordPress-based site that needs a tidy-up both on the front end and inside Google Search Console. Some pages are throwing errors and I’m seeing warnings that affect how the site appears in search results. I’d like an experienced WordPress troubleshooter who also knows their way around Search Console and the usual SEO diagnostics to step in, pinpoint what’s going on, and resolve it. Scope of work • Audit the live site, reproduce the issues I’m seeing and any you discover along the way. • Rectify the underlying problems in WordPress—whether that involves theme adjustments, plugin conflicts, database clean-up or performance tweaks. • Address every Search Console flag (crawl, index or structured-data related) so the property returns a...

I’m building a multiplayer, free-roam VR shooting experience for my arena and need an experienced Unity developer who can prototype and polish the entire game directly on Meta Quest headsets. The play space is an indoor arena and the core mode at launch is fast-paced Deathmatch, though I’d like the codebase to stay flexible enough to layer in Capture-the-Flag or other objectives later. Here’s what the job entails: • Create a bright, cartoonish visual style that keeps performance at 72 FPS on Quest 2/3 while still feeling lively and competitive. • Build all networking with Photon Fusion 2 so up to eight players can roam untethered, see accurate gun tracking, and swap seamlessly between PvP and team-versus-team matches. • Handle real-world arena alig...

I have a live mobile app on both iOS and Android that needs a full refresh. My priorities span three areas at once: • Sharpen the User Interface so the screens feel modern, consistent and intuitive. • Optimise Performance—faster load times, smoother animations, lower memory use. • Add a short list of new features that I will share once you have reviewed the current build. I’ll give you access to the existing repositories and an overview of the current architecture. After an initial code and design audit, I’ll need a clear action plan with milestones, then iterative builds I can test on TestFlight and internal Android tracks. Deliverables 1. Updated source code with in-line comments and a brief change log. 2. New UI assets integrated and pixel...

I’d like a private Survival server built on my Aternos account and fully loaded with the mods I enjoy. The focus is a smooth, vehicle-friendly experience for a small group of friends (no more than ten players online at once). Here’s what I need: • Install the exact Vehicle mods I specify (think MrCrayfish’s Vehicle Mod and similar). • Add reliable Optimization mods to keep tick rates healthy within Aternos’ memory limits. • Include a handful of Custom mobs and items mods that I’ll list for you. • Configure everything so the whole pack plays nicely together—no ID conflicts or broken recipes. • Tweak server and mod config files for performance, lag-free chunk loading, and stable TPS. • Test the server, then hand me ...

I need a seasoned C# desktop developer to sit with me for a focused 2–3 hour session and walk through the technical decisions behind an industrial-grade, SCADA-style application. My biggest dilemma is which UI framework gives the best performance for this use case—WPF, WinForms, or possibly something I have not yet considered. During the call we will review: • How each framework handles high-frequency, real-time tag updates from an OPC DA server and what that means for CPU, memory, and UI responsiveness. • Proven libraries or wrappers you rely on for robust OPC DA connectivity, plus scaling tactics for hundreds or thousands of tags. • Architectural patterns that make a drag-and-drop graphic screen designer maintainable. • Module boundaries, thread...

I’m building a niche blog centered on Health & Wellness and I need it taken from idea to live, optimized site. Two core areas must be built in from the start: • Workout routines section • Mental health advice section Everything else—from selecting or customizing a responsive theme and configuring the CMS (WordPress, Ghost, or a comparable platform) to basic on-page SEO and performance tweaks—should be handled so the blog is fast, clean, and easy for me to update on my own. Deliverables - Fully functional Health & Wellness blog online - Clearly separated Workout Routines and Mental Health Advice sections ready for content - Initial SEO setup (titles, meta, sitemap) - Short hand-off guide for future posts Please share links to any simila...

I need my new FortiGate 80F installed and fully integrated into the existing LAN so that the whole environment benefits from stronger security without sacrificing speed. The key outcome is a balance of protection and performance: traffic must be scanned, filtered, and shaped while keeping latency low for everyday business applications. Configuration requirements • Security posture – enable intrusion-prevention, anti-virus, and web filtering profiles that block known threats and unwanted content. • Internet use control – create policies that (a) block or allow specific websites, (b) throttle bandwidth for heavy-use categories like streaming, and (c) log user activity for later review. • Performance tuning – apply best-practice SD-WAN and bandwidth all...

I have a new NetApp system that needs to run as a dedicated Fibre Channel SAN. I need someone who can walk in (on-site) and take the array from factory state to a fully functioning, high-performing storage backbone for my servers. The work spans three clear areas: • Initial setup & configuration – rack-up checks, FC switch zoning, ONTAP initialization, aggregate & volume design, LUN creation, multipath setup on hosts, and end-to-end testing. • Troubleshooting & problem resolution – identify and clear any cabling, zoning, or protocol issues that appear during rollout. • Performance tuning & optimization – set best-practice queue depths, caching, and adaptive QoS policies so the array sustains peak throughput with low latency. I’m...

I want a lean, lightning-fast Python script that sits on Windows, continuously grabs a small, predefined rectangle of my BlueStacks window, performs real-time blob detection with OpenCV, and the instant a qualifying blob appears fires off a single, specific key press back to the emulator. The key points that matter to me are low latency capture, accurate blob filtering (size, colour or contour thresholding we can fine-tune together) and rock-solid keystroke delivery so the command never misses its timing window in-game. Please code the solution in plain Python with OpenCV as the imaging backbone; feel free to pull in lightweight helpers such as mss, pywin32, pynput, or pyautogui for screen capture and keyboard output as long as the overall loop stays responsive. I’d like the script...

I need a dependable AWS hand to jump in whenever a new EC2 instance has to be launched or an existing one re-configured. The core of the work is instance setup and configuration: choosing the right AMI and size, attaching and formatting volumes, assigning elastic IPs, creating or updating security groups, installing required packages, and handing over clean, well-commented documentation so I can track every change. Speed and clarity matter to me. Most requests will be short, same-day tasks, so I’m counting on you to respond quickly, follow best-practice hardening, and keep costs in check. Comfortable with the AWS console and CLI, IAM role creation, and snapshot scheduling is essential. While the immediate focus is EC2, skill with S3 or RDS would be appreciated for future phases. If...

I need an experienced integration engineer who can move comfortably across IBM WebSphere, Apache Kafka and Jenkins. All three platforms are in active use, so depth in each is essential. On the WebSphere side you’ll both develop and administer IIB/ACE message flows. Expect to create new integrations, refactor existing ones, tune performance and handle deployment automation. MQ and DataPower are equally important in our landscape, so you should be able to configure queues, security, high-availability and the corresponding policies on DataPower. Kafka underpins a real-time event pipeline. I’m looking for someone who understands topic design, partitioning, replication, monitoring and day-to-day administration. Experience writing and optimising producers/consumers is a plus. Jenk...

I already have a licensed WordPress theme installed and now need it tailored to match my brand as well as fully tuned for performance. Because the site targets a local audience, I’d like to work with a fellow Bangladeshi who understands our market nuances and can communicate easily during Dhaka office hours.
