Performans Optimizasyonu Jobs

I’m moving a bare-metal server at Hetzner over to a fully virtualized environment and want the foundation built right the first time. Here’s what I need: • Clean installation of the latest stable ESXi on the Hetzner host, followed by all current updates and patches. • Basic performance tuning so the hypervisor is ready for production workloads (CPU scheduling, datastore alignment, SSD caching if available, etc.). • Creation of well-structured subnets for multiple tenant VMs. • Firewall rules and protection logic on my MikroTik RouterOS appliance that will sit in front of the ESXi host, including NAT, filter, and basic DDoS hardening. I'm awaiting to order the server and necessary requirements for the setup; you will have to provide all require...

I have several enterprise-scale integration and data-migration initiatives kicking off right now and need an Azure Data Factory specialist who can jump in immediately for at least the next two months. The work centres on building, troubleshooting and optimising ADF pipelines that: • extract data from SQL Server and other database engines, plus a range of APIs (including Salesforce and S3 endpoints), • apply complex, rule-driven transformations, and • load cleansed results into a variety of target systems. You will own the whole lifecycle—from designing linked services and parameterised datasets, to writing highly-tuned SQL, to setting up monitoring and alerting so everything runs reliably at scale. I’ll look to you to surface and solve performance issues ...

My Baileys-based WhatsApp integration is working, but it is starting to lag under heavier traffic. I need an experienced developer who knows the Baileys library inside out to: • Profile the current code, identify the CPU, memory and I/O bottlenecks, and refactor or re-architect where necessary to improve throughput and lower latency. • Verify that every optimised change remains fully compatible with the Web version of WhatsApp, including session handling, QR login, message sending/receiving, media uploads and reconnection logic. • Provide a concise report of the issues discovered, the steps taken to fix them and before-and-after performance metrics (e.g. average response time, messages per second, memory footprint). Acceptance criteria – Messages and media must...

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,...
