    I have a working-but-fragile Chrome extension that crawls pages and “dorks” (niche search queries) looking for HTTP API tokens that match a specific regex. The job is twofold: 1. Repair and streamline the current codebase so the scanner reliably captures and locally stores every hit. Right now it sporadically misses matches and sometimes stops writing to storage. 2. Enrich the detection logic with fresh, private dorks and widen the sweep to cover the full set of indicators I care about: Keywords, Phrases, API endpoints, HTTP API strings and any related variations you can dream up.

    My in-house ERP, built with PHP 8, Alpine JS, and htmx, has a data-processing fault: new or edited records are failing to persist to the database. The problem shows up only in two modules—Inventory Management and Financial Transactions—while all other areas work as expected. The core workflow: a user edits a record, htmx issues an async POST, the PHP controller validates and writes through an ORM to MySQL. The front-end confirms success, yet the row never appears (or reverts on refresh). No errors are thrown in the browser console, but MySQL slow-query logs stay clean, so I suspect a logic or transaction issue in the controller or model layer.

    I need a full-stack, self-hosted .NET solution that runs a 2 × 2 matrix MLM system. The site must let new members register under a sponsor, automatically position them in the chain, and reflect spill-over earnings in real time. Core roles are Standard user, Sponsor and Admin. A registered user should see a clean dashboard that shows an earnings overview, live balance details and a searchable transaction history. From that same panel they must be able to deposit, withdraw or transfer BEP20-based USDT, with each on-chain action recorded to the ledger and mirrored instantly in the database. The admin control panel must allow me to browse every account, approve or reject any pending deposit/withdraw request, modify wallet addresses if needed, and trigger manual payouts. Every sensitive...

    I’m looking for a reliable computer operator who can keep our day-to-day information flowing smoothly. Your core focus will be entering new database records with speed and accuracy, watching over system dashboards to catch issues before they turn into problems, and turning raw activity logs into clear, well-structured reports for management. You’ll work directly inside our database interface for record entry, using Notepad whenever you need a quick scratch-pad or to clean up text before pasting it into the system. While the data itself is structured, attention to detail is critical because any typo can ripple through multiple departments. On the monitoring side, I’ll count on you to keep an eye on resource usage, job queues, and error alerts, then note anything unusual s...

    I’m in the start of a performance-focused data-migration effort that moves our current datasets into Snowflake, with Geneva and straight SQL powering the pipelines. To keep momentum, I need someone who can help on the hands-on analyst work while thinking like a Business Data Analyst. What I still have to finish centres on two areas: • Data extraction and transformation – mapping existing schemas, writing efficient SQL, and using Geneva/Snowflake utilities to cleanse and reshape data so downstream analytics run faster. • Data loading and validation – building repeatable load jobs into Snowflake, designing row-level and aggregate checks, and documenting reconciliation so stakeholders can trust the numbers. Acceptance criteria • Clean, reusable ETL scripts ...

    I need a clear, data-driven report that lets me monitor how satisfied end users are with our IT help desk. The ticketing system already stores all the raw data; what I’m missing is a concise view that translates that data into actionable insights. The report must zero in on three satisfaction drivers: • Response time • Resolution quality • Agent professionalism I’m happy for you to work in the environment you’re most comfortable with—Excel, Power BI, Tableau or a direct SQL‐based dashboard are all acceptable—so long as the final output is easy for non-technical managers to read and refresh on demand. Trend charts, scorecards, and a short narrative summary will help leadership see at a glance where we’re excelling and where we n...
