I’m looking for a quick-acting helper to set up, load, and keep tidy a Memcached cluster that will hold live user-session data for one of my web applications. The instances are already provisioned; what I need is the expertise to populate them efficiently and keep them healthy under constant read/write traffic. Your focus areas • Script the initial population, including key naming conventions, TTL rules, and eviction strategy settings so the cache performs predictably. • Build lightweight maintenance jobs that purge stale or orphaned keys without interrupting active sessions. • Add basic monitoring hooks (Prometheus, Datadog, or a tool you prefer) so I can track hit/miss rates, memory usage, and slab fragmentation in real time. • Deliver concise documenta...

Thousands of lines of T-SQL that once worked are now returning incorrect results. I need a fresh set of expert eyes to comb through the entire script, pinpoint exactly where the logic breaks down, and fix it. The code lives in SQL Server. While you work through the main script, I also need you to cascade several hundred new parameters into a series of dependent stored procedures. These procedures already compile; they simply require the additional parameters to be wired through correctly so downstream calculations stay consistent. What I expect from you: • A clean, corrected version of the original query and any touched procedures • A concise change log explaining the root cause of the logical error and how you resolved it • Updated stored procedures with the new param...

I run an educational mobile application that is already live on both Android and iOS. I’m looking for a seasoned full-stack developer who can jump straight into the codebase, roll out new features, and then stay on as the go-to person for annual maintenance, performance tuning, and bug fixing. You will be touching the entire stack—mobile front-end for Android and iOS as well as the server side and database layer—so confidence switching between platforms, APIs, and deployment pipelines is essential. When you reply, focus on your relevant experience. I’d like to see where you’ve shipped cross-platform features, kept apps healthy post-launch, and managed long-term maintenance for a live product. Code samples or links to production apps will help me assess fit q...

I maintain a growing web application written in both Rust and Go and I’m looking for a US-based native English speaker who can jump in confidently on the server side. The codebase relies on Rust’s Actix and Rocket frameworks alongside Go’s Gin router, so recent hands-on experience with all three is essential. Your first priorities will be twofold: shipping new user-facing features while also hunting down and patching the most visible bugs reported by our QA team. Performance tuning and architectural refactors are handled by another engineer, so your focus stays squarely on feature work and defect resolution. To make sure we stay aligned, here’s how I’ll review your work: • A concise pull request for each feature or fix, passing our existing CI tests. ...

My store’s homepage feels sluggish and I can see the bounce rate creeping up. I need a Shopify specialist to dig in and noticeably improve loading speed without hurting design, functionality, or SEO. Priority • Homepage performance. Product pages and checkout are fine for now, but any global tweaks that help everything load faster are welcome. Current setup • A few third-party apps are installed. Most are marketing or review widgets; I suspect one or two of them—and unoptimized imagery—are slowing things down. What I need from you 1. Benchmark the current homepage speed (Google PageSpeed Insights or Shopify Analyzer). 2. Identify bottlenecks: theme code bloat, render-blocking assets, oversized images, unused app scripts, etc. 3. Optimise: minify CSS...

I need an Azure-based file server set up from scratch so my team can use it primarily for secure file storage of everyday documents and spreadsheets. Roughly 11 – 50 colleagues will be connecting, so permissions, performance and reliability all have to be configured with that scale in mind. The job covers creating the storage account, provisioning an Azure Files share, integrating it with Azure AD/AD DS for seamless authentication, and mapping it so Windows and macOS users can access it as a standard network drive. I also want quota alerts enabled and a clear backup snapshot schedule so nothing is lost. Once the share is live, I’ll need a concise hand-over guide that shows how to add or remove users, adjust NTFS-style permissions, and expand capacity later. Deliverables: &bu...

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.

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...

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, ...
