I need a senior Delphi mind to craft a clear-cut strategy for moving an existing application from the Borland Database Engine to FireDAC with SQL Server as the back end. The objective is full modernization: cleaner code, easier maintenance, and freedom from legacy BDE constraints. I will spin up a dedicated testing environment first, so your plan must assume zero changes touch production until every issue is ironed out. Please lean on practical experience—show me similar projects you have already steered; past work is my main filter when choosing who to collaborate with. Deliverables • A written migration roadmap outlining phases, timelines, and required tooling • A checklist for preparing the test instance (drivers, FireDAC components, SQL Server settings, connec...

I keep seeing high RAM utilisation on both Oracle Linux and Red Hat Enterprise Linux servers and I want to understand, in depth, what is really happening inside the memory subsystem. More than a quick fix, I need a knowledgeable administrator who can walk me through each layer—kernel, user space, buffers, cache, swap—so I can read the numbers with confidence and spot the true culprits when usage spikes. Here is what I expect from our collaboration: • A live, step-by-step session (or series) where we run commands such as free, top, vmstat, sar and others you recommend, interpret every column, and relate the output to the kernel’s behaviour. • Practical explanations of how Oracle Linux and RHEL may differ in their memory reporting and tuning parameters. &bull...

I have an existing UNX universe already in daily use by the Sales team and I need an experienced SAP IDT developer who is equally comfortable with SAP S/4 HANA reporting to extend it and refresh our Web Intelligence sales dashboards. Scope of work • Universe updates: the job is strictly about modifying the current universe, not creating a new one. You will add the objects the analysts keep asking for—new dimensions, measures and hierarchies—so they can slice revenue, margin and forecast data the way they need. • S/4 HANA alignment: everything you add must pull from the correct CDS views or calculation views in S/4, with naming and aggregation rules that match the existing data model. • Report enhancement: once the universe is updated, I want at least three...

My site drags its feet on first load and Google’s PageSpeed Insights backs that up: From what I can tell the homepage is the main culprit, but I don’t yet know whether it’s images, scripts, or something else. I need a clear, data-driven diagnosis followed by practical fixes that move the mobile score into the green. Here’s what I’m looking for: 1. A concise technical audit of the homepage that pinpoints the bottlenecks (network waterfall, render-blocking resources, unoptimised media, plugin bloat, etc.). 2. A step-by-step plan of what to optimise, in what order, and why it matters. 3. Implementation of those recommendations—image compression, lazy-loading, CSS/JS minification, caching strategy, or whatever the audit proves necessary—w...

I want someone to fix my site optimization again. There are issues with layout shift on the page, and Elementor isn’t running reliably. It shifts all the containers every time the page loads. The site optimization is handled via Perfmatters, and caching is done with the LiteSpeed Cache plugin. Even if both are disabled, the issue still happens. So it must be related to WordPress and Elementor.

I’m integrating a small yet critical X86 routine into a larger, production-grade application and need a seasoned assembly programmer to jump in quickly, finish the code, and prove it works with a clear screenshot of the routine executing correctly. You will receive my current source and a brief on the expected behaviour. Tweak, extend, or completely rewrite the segment—whatever delivers a clean, working solution that slots straight into our existing build. Accuracy matters more than elegance, but if you can squeeze in a performance gain, all the better. Please return: • The updated .asm (or .s) file and any supporting files • A short note on what you changed and why • A screenshot of the program running and producing the expected output in a terminal or d...

I run a data platform built on Spark and Python, and I need an experienced engineer who can sit with me in Pune three to four times a week (hardly 2 hours in a day) to keep it running smoothly. Most of the immediate work revolves around tracking down bugs in existing PySpark jobs, but the role naturally extends to writing fresh code when gaps appear, tightening our data-pipeline orchestration, and mapping end-to-end data lineage so every downstream consumer stays confident in their numbers. Typical day-to-day work you will tackle: • Debug production PySpark jobs and accompanying Python utilities • Refactor or rewrite modules where quick fixes will not suffice • Optimise and monitor pipeline schedules (Palantir Foundry) • Document lineage and hand off clear, repro...

I'll provide the source code and details after hiring. If you have solid experien...

My SharePoint 2019 farm has suddenly lost its Distributed Cache functionality. AppFabric is reporting corruption, user profiles refuse to provision, and overall farm performance has taken a noticeable hit. I have not changed any system configurations nor applied any patches or updates before the failure occurred. I need an expert who can: • Diagnose and repair the AppFabric installation that underpins Distributed Cache. • Re-provision and bring the Distributed Cache service online so user profile synchronization works again. • Validate that cache hosts are correctly joined to the cluster and confirm no residual data loss or throttling issues remain. • Document the steps taken and any PowerShell commands used so I can replicate the fix in a disaster-recovery sce...

I’m updating the firmware for an STM32-based design and need an experienced C++ developer who is comfortable inside STM32CubeIDE. The codebase already compiles and runs on the microcontroller, but several features still require clean, well-structured implementation, performance tuning and thorough testing directly on the hardware. You’ll be working exclusively with STM32 microcontrollers; no FPGA or other targets are involved. Please be ready to pull the current CubeIDE project from my repository, build it as-is, and then extend it in C++17 (or later) while respecting the existing HAL layer and project structure. Deliverables • Updated CubeIDE project with the new or fixed functionality fully integrated • Clear build instructions and a short change log so I can ...

I have a mature React codebase , and i need some to help me with some task one day

I run a Canadian real-estate search engine that must stay lightning-fast for genuine home-hunters while remaining fully crawlable by Google, Bing and other reputable AI/search bots. Right now Cloudflare shows ±100 k daily hits from malicious, spam and scraper bots; that traffic spikes the servers, ruins bounce-rate metrics and occasionally knocks the site offline. I have already: • Placed the site on Cloudflare, • Allowed full, captcha-free access for visitors inside Canada, • Forced most other countries through a captcha, • Experimented with firewall rules, IP and UA blocking. Unfortunately, Google’s crawler activity drops whenever the shield becomes too strict, so I’m looking for an expert who can strike the sweet spot: block malicious...

I need an experienced Windows specialist to jump in remotely and keep my small network running smoothly. The environment spans Windows Server 2016, Windows Server 2019 and a handful of Windows 10 workstations. Typical assignments range from one-off fixes to short configuration sprints, so I’m looking for someone who can respond quickly, diagnose accurately and document any changes made. Scope of work Over the coming weeks I expect help with: • Service configuration – DNS, Active Directory, and File & Print Services • Issue troubleshooting – anything from failed roles or features to odd workstation errors • Performance and security checks – tightening policies, reviewing event logs, tuning resources You will connect via remote session (VP...

Heavy bursts of visitors are knocking my landing page offline. Each spike fills the nginx error log with 2026/02/09 20:32:47 [error] 949181#949181: *409046 connect() to unix:/var/run/php/ failed (11: Resource temporarily unavailable) while connecting to upstream, client: , server: , request: "GET /pW321xkxUy/?zoneid=9843359 HTTP/1.1", upstream: "fastcgi://unix:/var/run/php/:", host: "" I’ve confirmed the trigger is a high number of simultaneous users, not bots or unusual request types. What I need—urgently—is a Linux-savvy engineer who can stabilise the stack so the site stays up no matter how fast traffic arrives. Stability and uptime are my top priorities; raw speed tweaks are welcome only if they don’t compromise resilience. You...

My PHP 8.x application has picked up a fair amount of dead weight—unused files, legacy snippets, and the odd warning that only shows up in the logs. I need a developer who can open the hood, keep what truly matters, and scrap the rest while making sure everything that stays runs flawlessly. Here’s what I’m asking you to do: • Read the entire codebase, identify the core file(s), and strip away anything that isn’t required. • Hunt down every notice, warning, or fatal error and resolve it so the script executes cleanly on PHP 8.x with error reporting turned up. • Where you see obvious performance wins—query consolidation, tighter loops, lighter includes—go ahead and tune them. • I’m not entirely sure which smaller features ...

My custom e-commerce site is built on Laravel, not on Shopify or WooCommerce, and I need a sharp developer to tidy up a few pain points. First, a handful of pages are throwing 404s or directing to the wrong place. I’d like those links traced, corrected, and any underlying routing issues cleaned up so future content changes don’t break again. Second, page loads feel sluggish. I’ve spotted heavy database queries, un-optimised images, and a couple of third-party integrations that look chatty. I’d like you to profile these bottlenecks, refactor the queries, compress or lazy-load media where it makes sense, and audit the external calls so they only fire when truly needed. Deliverables • All broken links/pages resolved and verified • Average page load tim...

Project Description My current production workload runs entirely on AWS EC2, and while usage grows, monthly costs are increasing and application response times are degrading. I’m looking for an experienced AWS / DevOps engineer to perform a data-driven infrastructure audit and recommend optimizations. The engagement will begin with a deep-dive assessment of the existing environment, followed by a cost- and performance-balanced architecture proposal. All findings must be supported with measurable evidence, not assumptions. Phase 1 — Infrastructure Audit The audit should cover: EC2 CPU, memory, and disk I/O utilization Database behavior and performance (MySQL) Network flow and latency analysis CloudWatch metrics and logs review Identification of bottlenecks, ...

I run several mission-critical applications on AWS and I’m looking for a seasoned C#/.NET engineer who can extend our backend, shape new APIs, and keep deployments rock-solid. Day-to-day you’ll work with AWS Lambda for serverless jobs and EC2 for long-running services, containerise everything in Docker, then roll it out to our Kubernetes clusters. All data lives in SQL Server, so you’ll need to be comfortable with T-SQL, indexing, and performance tuning. Development happens on Linux, version-controlled with Git, and we sync up during US-CST hours—daily status notes are required so nothing slips through the cracks. Compensation is in the USD 500-1,000 monthly range and can scale with proven results. WPF, Redis, Grafana, or SIP/VoIP expertise would be a welcome ...

I’m ready to launch an e-commerce storefront and need someone who can take the project from blank page to live, fully-tested site that loads quickly and functions flawlessly. The core build must include: • Product search with robust filtering so shoppers can zero in on size, color, price, or other attributes in milliseconds. • A clean review and rating system that feels native to the store, encouraging trust and repeat sales. • Multiple payment gateways (credit/debit, wallets, and at least one local option) configured and verified in both test and live mode. I haven’t locked myself into Shopify, WooCommerce, Magento, or any other stack yet, so if you can justify a platform choice—or even propose a headless solution that outperforms the usual suspects&...

My BMX-lifestyle site, , is built the old-school way—pure HTML, CSS and a touch of JavaScript. I need a developer who can give it a spring-clean so every page loads fast, looks brighter and delivers a smoother ride for visitors. Here’s what I’d like done: • Performance tune-up – audit the current code, compress images, minify and combine files, and add any light-weight caching or lazy-loading tactics that make sense for a static build so pages feel instantly responsive. • Visual polish – keep the bold, bright and colourful vibe but tighten spacing, tweak typography and clean up any inconsistent styling so the overall design feels cohesive. • Subscription button – drop a clearly visible opt-in (Mailchimp, TinyLetter or similar; I&rsqu...

My Linux server is ready, Laravel is in place, and I now need gblicense v15 fully installed, configured, and served through an Nginx reverse-proxy. Default gblicense settings are acceptable; the key requirement is that every feature runs smoothly behind the proxy without breaking existing Laravel routes. What you will do • Compile or obtain the correct gblicense v15 binaries, deploy them to the server, and wire them up to the current Laravel stack. • Configure Nginx as the single entry point, including HTTPS termination (certbot is already available) and clean routing so that gblicense runs on its intended port while remaining invisible to the end user. • Optimise basic network security inside the app and proxy layers (a separate firewall is not planned). • Tro...

We are looking for an experienced developer to build a small Linux utility that communicates with a U.2 NVMe SSD over SMBus (NVMe-MI). The project involves low-level hardware and software work, not application development.
