Performance Tuning Jobs

Hi! I run a Minecraft server that currently relies heavily on Skript-based custom features and several existing plugins. I recently joined another server that feels like a "perfected version" of what I’m trying to build — smoother, more polished, and better optimized. I need a Minecraft server specialist who can: Audit & Replicate — Join the reference server (IP provided via PM), identify what plugins, configurations, and mechanics they use to achieve that level of polish, and replicate the relevant setup on my server. Build from Scratch — Set up a complete survival-mode server from zero, optimized for 100–200 concurrent players with zero lag spikes. Preserve & Optimize Existing Features — Several custom features and systems already exi...

My website is overdue for a tune-up and I’m ready to tackle three things at once: faster performance, sharper visuals, and a clean backlink profile. 1. Core objective The top priority is speed and overall site performance. I want noticeably quicker load times and a smoother experience on every device without sacrificing functionality. 2. Visual refresh Only the imagery needs an update—no logo or typography changes for now. I’ll supply new photos and graphic assets; your task is to optimise, compress, and work them into the existing layout so they look crisp while keeping file sizes lean. 3. Backlinking & minor fixes I also need a small-scale backlinking push to strengthen domain authority plus a sweep of minor on-site issues (broken links, console errors, any...

I have a production-support ticket that I need to close quickly. The Azure Data Factory pipeline is taking too much time to run when it reaches the step that calls a SQL script, and the underlying issue appears to be performance-related within that script. Your task is to jump into my Azure environment, pinpoint the root cause, and get the pipeline running cleanly end-to-end. What you’ll tackle • Debug the pipeline activity that integrates with the SQL script. • Tune or rewrite the script so it runs efficiently without timing out or over-consuming resources. • Validate by triggering the pipeline in Production and showing a successful, performant run. I’ll provide access to the ADF workspace, the pipeline, monitoring logs, and the current SQL code. Once th...

I run a corporate website whose desktop performance is fine but whose mobile load times are hurting conversions. The biggest pain point is oversized imagery, so the first priority is to resize, compress, and serve images through proper lazy loading. Once the images are under control, I need an effective caching layer. I have no preference between WP Rocket, W3 Total Cache, or another reputable solution—choose what lets us hit the best Core Web Vitals numbers. Heavy or redundant plugins should be audited and removed where safe. Please minify, combine, defer, or otherwise optimise CSS and JavaScript so that the Largest Contentful Paint slips comfortably into the green zone. A gentle database clean-up (post revisions, transients, overhead) will finish the tune-up. Deliverables ...

I run several production workloads on Oracle 19c and need an expert DBA who can handle three core activities for me around the clock: building new databases from scratch, tuning performance on existing instances, and carrying out version or patch upgrades without downtime to the business. Here is what I expect from you: • Database creation – end-to-end installation and configuration of fresh Oracle 19c environments, including listener setup, tablespaces, and all basic security hardening. • Performance tuning – proactive monitoring and remediation using AWR/ASH reports, SQL Tuning Advisor, indexing strategies, and statistics management to keep response times low. • Upgrade & patching – planning and executing PSU/RU installs or full-version upgrades...

I’m extending an existing ecosystem that runs on both Laravel and CodeIgniter. The immediate priority is new feature development: fresh modules, REST-style endpoints and the related MySQL schema changes that make the data flow clean and fast. All work lives in a Git repository and must be written with maintainability in mind, so clear commits and meaningful messages are essential. You’ll be touching every layer of the stack. On the back end that means PHP 8+, eloquent database design, query optimisation and careful performance tuning. On the front end you should feel comfortable wiring your controllers to lightweight views styled with plain HTML, CSS and vanilla JavaScript—nothing fancy, just clean, responsive interfaces that match our existing look and feel. Typica...

I need a concise, data-driven assessment of my site’s performance, with the priority on how quickly the product pages render for users. I’ve noticed delays that hurt conversions, so I’d like clear diagnostics—think Lighthouse, PageSpeed Insights, or GTmetrix—and a practical action plan that pinpoints the elements slowing things down. Please test across desktop and mobile, detail the root causes, and outline the fixes in order of impact. A short follow-up call to walk through your findings and answer questions will round off the engagement.

My site has started throwing form-submission errors and overall page speed has dipped, so I need a focused cleanup. The first priority is to get every form submitting reliably again. While you’re inside the form logic, please switch the date field to the new format I’ll supply, introduce a couple of new data fields, and strip out any obsolete ones I point out. Loading time is the next pain point. I’m looking for pragmatic optimisation—compressing heavy assets, tweaking queries, improving caching—whatever brings the site back to a snappy response without a full rebuild. Finally, the WhatsApp button needs a quick tweak: change the pre-filled message text so that it pulls a short template I’ll provide. The button’s position and core functionality ca...

WordPress VPS Performance Issue We have a VPS server with several WordPress websites. The server is not overloaded (CPU/RAM usage is normal), but the websites are loading very slowly and lagging. We need an experienced freelancer to identify the cause and fix the issue. Server and WordPress optimization may be required. Please contact us with your experience and estimated time to resolve the problem.

I’m a full-time developer working directly in a live Guidewire ClaimCenter environment and I keep running into questions that slow me down. Most of my challenges revolve around writing efficient, optimized Gosu code that still respects ClaimCenter conventions and integrates cleanly with the existing services we already have in place. I have several code-quality and optimization tools running in the pipeline, so guidance will need to mesh with those rather than start from scratch. What I need is an ongoing, hands-on mentorship: quick walkthroughs when a production incident pops up, deeper sessions where we dissect the current implementation, and regular checkpoints to review the efficiency of new logic before it reaches production. You’ll also help me confirm that documents gen...

My desktop has been running noticeably slower for a few weeks, right after I installed some new software. I’d like a seasoned PC technician to jump in remotely, diagnose the exact cause, and restore normal speed without losing any of my data or settings. Key details you should know: • Current issue: Slow performance • Onset: Began a few weeks ago • Recent change: Installed new software prior to the slowdown What I need from you: • Perform a full system health check (CPU, RAM, disk, background processes) • Identify and remove unnecessary startup programs or bloatware • Verify the recently installed software isn’t hogging resources or conflicting with drivers • Clear temporary files and optimize system settings for better responsiveness •...

I work full-time on a live Guidewire ClaimCenter implementation and regularly handle production incidents—everything from mis-routed documents to integration hiccups. While I can usually patch issues, I want to move beyond quick fixes and truly master the platform. My immediate focus is on Coding best practices in Gosu. I often find myself guessing when it comes to structuring classes, optimizing performance, or leveraging the framework’s more powerful constructs. To sharpen my skills, I need long-term, hands-on mentoring that covers: • Advanced features and techniques in Gosu (refactoring pattern code, metaprogramming, performance tuning, and testability) During our sessions you’ll walk me through real tickets, explain why a particular solution works in ClaimCent...

The core of my pets-services platform is already running on C#, ASP.NET Core and SQL Server, but only part of the roadmap is complete. I need a developer who can dive into the existing repository, understand what’s been built so far and then work alongside me, sprint by sprint, until we launch. and after we launch stay with me to develop it more. Where things stand • Current status: partially developed. Key models, some controllers and basic pages are live, but several workflows still stop at stubs or placeholders. • Guidelines: I have an architecture outline, UX wireframes and a list of required endpoints; however, I’m open to your recommendations on best practices, performance tuning, and UI polish. What you’ll be picking up – Clean up and extend...

I need a cross-device video player built for Android TV, tablets, and phones, replicating the complete experience of MX Player. The core must include smooth subtitle rendering (multiple formats, online/offline), responsive gesture-based controls for brightness, volume, and seeking, plus reliable hardware acceleration so even high-bit-rate files play without stutter. Beyond those headline items, I expect the familiar MX staples—playlist handling, aspect-ratio toggles, background playback, and on-screen codec info—to feel just as polished on all three form factors. A single code-base that detects screen class and adapts its UI is ideal; Jetpack Compose or standard XML layouts are both fine as long as Leanback guidelines are respected on TV. Because I’d like to move quickl...

My Shopify store is ready for a performance and accessibility tune-up focused primarily on the product pages. I need an experienced developer who can dive into the theme code, installed apps, and page assets to squeeze out every millisecond of speed while making the site friendlier to all users. Performance goals – Audit all scripts and apps loaded on product pages, keeping only what is essential and rewriting or deferring anything that slows First Contentful Paint. – Re-compress and properly size images, SVGs, and other media across the store. – Address any Core Web Vitals warnings flagged in Lighthouse or Google PageSpeed Insights. Accessibility upgrades The most pressing fixes are on product pages, specifically: • Correct, programmatic form labels for ...

My Ubuntu-based server runs Nginx as both the webserver and an HTTP reverse proxy. Despite average utilisation staying below 50 %, I keep running into three intermittent problems: • the nginx service suddenly stops, • the whole OS occasionally freezes, and • some requests return 500 errors even though the upstream application is healthy. What I need from you is a full-scope diagnosis, clear explanation of the root cause(s), and concrete fixes. That will likely involve: • auditing current nginx and systemd settings (nginx ‑T, unit files, , etc.), • analysing kernel, journal and dmesg logs for memory, I/O or cgroup problems, • stress-testing and reproducing the 500 responses, • tuning worker processes, buffers, time-outs and any OS limit...

I’ve just finalised our new brand, positioning and messaging with an agency and now need that work translated into a polished online presence. Because we’re a boutique B2B cyber-risk management firm, the site has to project a professional, corporate feel—clean lines, restrained colour palette, crisp typography and flawless responsiveness. Scope of the build • Incorporate all updated copy and visuals • Create a dedicated case-study area where each story features client testimonials, a clear problem–solution breakdown and measurable results. • Build a resource hub that supports downloadable documents and a searchable article library, with an easy back-end for future uploads. • Add an events & webinars section my team can update wi...

My WordPress site works, but it still feels sluggish. I’d like a specialist to focus on improving raw loading speed, with particular attention on the homepage and key product pages where most visitors land and convert. If you spot additional quick wins elsewhere—say, inside a long-tail blog post—that’s a bonus, yet the brief is firmly anchored on the pages that make the business money. Here’s what I expect the engagement to cover: • Run an initial performance audit (Core Web Vitals, GTmetrix, Lighthouse or similar) to create a clear before-and-after benchmark. • Optimise code, assets and queries: efficient caching, image compression, script deferral, tidy database tables, and any necessary theme or child-theme tweaks. • Review plugins only...
