Performance Tuning Jobs

My priority is to build and refine Microsoft Dynamics 365 Business Central through new AL objects, with the spotlight on custom tables and pages. These pages must support clean data entry, run their own validation, trigger custom workflows, and surface key metrics in dashboard-style reports. Beyond the UI layer, I need business logic that enforces bespoke validation rules and handles data integration processes so information moves reliably between internal modules and any external systems we connect later. Additional work will include, when required, adjusting RDLC or Word layouts for reports, extending posting and approval workflows, exposing data through APIs or web services, and tuning SQL for performance. Deliverables • AL code for tables, pages, and supporting codeunit...

I manage our university’s Student Information System and need a technically savvy partner to keep it running at peak performance while we expand its capabilities. Day to day, the work ranges from fine-tuning system configuration, maintaining a clean permission hierarchy, and automating routine admin tasks, through to digging into database queries when the system slows down or an integration drops data. You’ll be hands-on with: • System configuration & ongoing management • User account lifecycle, roles, and permissions • Reporting, analytics, and custom queries Current pain points I want resolved quickly: • Intermittent performance slow-downs during high-traffic periods • Data integration failures between the SIS and our LMS/HR platforms ...

Shopify-based D2C home decor brand Current Google PageSpeed Insights score: 30 on mobile, 50 on desktop Looking for a real, verifiable improvement in load speed and core vital score on PSI — the deliverable will be checked against live PageSpeed Insights results, not a screenshot All existing apps must remain installed and fully functional (reviews, chat, upsells, etc.) — no removing or disabling app features All tracking/analytics scripts (Meta Pixel, Google Analytics, GTM) must continue to work exactly as they do now — these should not be touched Cart and checkout functionality must not be affected in any way Work must be done on a duplicate/unpublished theme first — you'll get admin access, and we'll review a preview link before anything is published ...

My website is starting to feel sluggish and I’d like a specialist to tune every layer of the stack so pages load noticeably faster. The three pain points I need addressed are page-load speed, server response time, and database optimisation. I will be tracking progress in Pingdom, so each change should show a measurable before-and-after gain there; if you want to validate with Lighthouse, GTmetrix, or any other tool that’s fine, but Pingdom is the baseline. You’ll begin with a quick audit, documenting the current scores and the main bottlenecks. From there, I expect iterative fixes—caching rules, image and asset compression, query/index tweaks, web-server or PHP-FPM tuning, whatever the data tells us will move the needle most. Please keep a short change-log so I can...

My brand-new build refuses to see all of its memory. The board is an ASRock Z890 Taichi and, although the system powers up, it immediately throws RAM-related beep codes and the BIOS reports no modules installed. I’d like an expert who can walk me through a systematic BIOS and hardware diagnosis—remotely via video or chat—and pinpoint whether the problem is slot, stick, firmware or setting related. Once a clear culprit is identified, I will implement the hardware swaps or firmware flashes you recommend and report back so we can confirm the result together. Acceptance criteria • All installed DIMMs appear at their full capacity and correct speed in BIOS. • System completes at least three consecutive error-free boots into Windows. • No further memory-r...

The current build of my iOS app opens noticeably slower than it should, and that single issue is hurting the overall user experience. I need an experienced iOS engineer to zero-in on the root causes, streamline the launch sequence, and deliver measurable gains in raw loading time. What you will be doing • Profile the project with Xcode Instruments (Time Profiler, Launch Time, and any other tools you prefer) to identify bottlenecks in startup code, heavy asset decoding, blocking network calls, or mis-configured Core Data operations. • Refactor, defer, or cache expensive tasks so the first screen becomes visible as quickly as possible, while keeping code readability intact. • Supply before-and-after metrics (cold and warm launch) captured on at least one recent iPhone r...

I’m dealing with incessant pop-up ads in Google Chrome on my Windows PC and I’m convinced a piece of adware or a browser hijacker has slipped in. I haven’t run any antivirus or malware-removal utilities yet, so the system is essentially in its original infected state and ready for a full clean-up. Here’s what I need from you: • Identify the exact source of the infection (extensions, policies, hidden processes, scheduled tasks, registry keys, etc.). • Perform a complete Chrome and system scan using trusted tools such as Malwarebytes, AdwCleaner, or any utility you prefer, then remove every malicious component you find. • Reset or harden Chrome settings, clear suspicious policies, and ensure only legitimate extensions remain. • Provide a co...

I need a reliable WordPress specialist to keep my site healthy and running smoothly on a quarterly basis. The immediate focus is on routine security updates and staying on top of general plugin updates, with special attention to the existing security plugin and an image-optimization tool that helps keep media lean. Two issues require prompt resolution: 1. Slow-loading pages that are hurting user experience and SEO. 2. Intermittent error messages that appear on a few key pages. Your work will involve: • Applying the latest WordPress core, theme, and plugin updates without breaking existing functionality. • Auditing and tightening security settings, particularly within the current security plugin. • Optimizing performance—caching, image compression, or other best-p...

I’m assembling a short-term roster of interviewers who can rigorously assess candidates for senior-level Big Data roles, with a sharp focus on Apache Spark. Your job is to join my panel, run live technical interviews (remote video), probe deep into real-world Spark architecture, coding, optimisation and troubleshooting, then deliver a concise written evaluation of each candidate’s strengths, gaps and hire/no-hire recommendation. I will supply the role description and résumé ahead of time; you bring the questions, white-boarding scenarios or live-coding prompts you rely on in your own Spark projects. Familiarity with the wider ecosystem—Scala or PySpark APIs, performance tuning, cluster resource management, integration with Kafka or Hadoop—is welcomed,...

I have a 2021 Rec Room project that no longer boots cleanly. Installation fails, runtime errors pop up, and overall performance has taken a noticeable hit. I can share the full source through Google Drive as soon as we start. What I need: • Debugging errors that stop the build from launching • Light performance tweaks once everything is running Deliverables: 1. A fully working build that opens without error 2. Clearly commented code or a short change-log explaining every fix and update you applied. 3. A quick rundown (video call or written summary) of any future-proofing steps I should know. Because I’m working off a small personal budget—about $150 total—I’d like to agree on milestones upfront so we both stay on track. If this sounds doable, let ...

I need a freshly created DigitalOcean droplet configured as a production-ready web server running Apache. You will handle the entire setup process, from spinning up the droplet to handing back SSH access and a short hand-over document so I can deploy sites immediately. The job covers: • Droplet creation (Ubuntu preferred) and initial hardening • Full Apache installation and configuration, including virtual hosts for multiple domains • SSL via Let’s Encrypt with auto-renewal • UFW or equivalent firewall rules allowing only required ports • Swap file, basic tuning, and any best-practice performance tweaks • DNS guidance so the domains point correctly once records propagate Once everything is live, a brief checklist documenting commands run, l...

I need a small but robust utility that runs on Nintendo Switch 2 and helps players squeeze the best possible performance out of their games. The core focus is performance optimisation: analysing in-game behaviour, identifying bottlenecks on the fly and applying smart tweaks so titles load faster, maintain steadier frame rates and feel more responsive. What I picture is a lightweight overlay or background service written in C/C++ (or another language supported by the official Switch 2 SDK) that: • profiles CPU, GPU and memory usage in real time, • applies dynamic setting adjustments or recommends the ideal presets, and • logs before/after metrics so users can clearly see the gains. SDK-compliant code, clean architecture, and clear developer documentation are es...
