لدي منظومة تعمل بالفعل وأحتاج إلى مطوّر برمجيات خلفية محترف يركّز حصرياً على تحسين الأداء فيها، وبالتحديد رفع درجة تحمّلها عندما تتعرّض لأحمال مرتفعة. الهدف هو أن يستمر النظام بالاستجابة بثبات وسرعة حتى عند الذروة. سأزوّدك بكل ما يلزم من شفرة حالية، سجلّات، وبيانات الاختبار. المطلوب منك تحليل عنق الزجاجة، تنفيذ التعديلات اللازمة — سواء كانت إعادة كتابة أجزاء من الكود، تحسين الاستعلامات، أو إدخال حلول تخزين مؤقت وتوزيع الأحمال — ثم توثيق النتائج بالأرقام. قبولي للتسليم يعتمد على: • تقرير قياس أداء قبل/بعد يتضمّن أوامر الاختبار والأدوات المستخدمة • كود مُحسَّن ومعلَّق بوضوح • إرشادات نشر سريعة تمكّنني من تفعيل التغييرات على بيئة الإنتاج إن كنت متمرساً في ضبط الأداء، أدوات القياس، واختبار الضغط، فسيسعدني العمل معك.

I need someone who can jump on a screenshare with me right away and push my Shopify storefront into the green on Google PageSpeed Insights. My own tests show slow page loading, unoptimized images, and excessive script calls, so the job is laser-focused on three fronts: • Page-load time – core pages must feel instantaneous on desktop and mobile • Image optimization – compress or convert without hurting visual quality • Script minification – trim, defer, or combine Liquid/JS wherever possible You’ll be working live on a remote session; no direct store access is provided outside that call. Please bring proven Shopify theme-level experience, a solid grasp of Liquid, JS, and modern performance tooling, and be comfortable explaining each change before...

My production SQL Server is running on an Azure VM that was originally provisioned with a 500 GB managed disk. The database itself sits comfortably below 120 GB, so I’m paying for far more storage than I need. I want to shrink the provisioned space to 120 GB and cut the monthly bill, but I cannot afford even the slightest data loss in the process. Here’s what the job entails. You will: • Analyse the current 500 GB environment, confirm the live data footprint and identify everything that must move. • Safely shrink and migrate the database to a new 120 GB disk (or resize in place if that proves cleaner) while retaining all indexes, stored procedures and user accounts exactly as they exist today. • Optimise the VM and SQL configuration so performance stays sta...

My current iPhone app needs a smoother, faster experience and a navigation flow that feels intuitive from the first tap. User-interface focus • Add clear, context-aware menus so key tasks surface naturally. • Strip down or merge cluttered menu items to keep journeys under three taps. • Build a more responsive search that returns results instantly and can filter as the user types. Performance tuning Behind the scenes, I want launch times cut noticeably and in-app transitions to stay silky even on older devices. Memory spikes, dropped frames, or slow API calls should be profiled and optimised until they pass Apple’s performance metrics. Acceptance criteria 1. Average cold-start <2 s on an iPhone 11. 2. No frame drops (>60 fps) during standard n...

I need an experienced Snowflake professional to own the end-to-end data integration of several AWS and Azure sources into my Snowflake environment. Your first objective is to design and build reliable, automated pipelines—using Snowpipe, Streams & Tasks, or any proven approach—that land raw data in a staging area and promote it through to curated models without manual intervention. Beyond the load process, I also want the warehouse running at peak efficiency. That means: • tightening query performance, • setting up the right clustering or indexing strategies, and • fine-tuning resource management so we only pay for what we truly use. Because my in-house team will maintain the solution, I’d like you to spend dedicated time as a trainer, walking us...

We recently upgraded our ERP system's frontend to Angular 20.3.19 and backend to ASP.NET Web API 2 and .Net Framework 4.7.2 Since the upgrade, the application has become noticeably slower — page loads, data grids, and API response times have all degraded compared to the previous version. We're looking for an experienced full-stack developer (or a pair — one Angular specialist, one .NET specialist) to diagnose and fix the performance regression. Scope of Work • Profile the application to identify what's causing the slowdown (frontend rendering, change detection, bundle size, API latency, DB queries, etc.) • Review Angular 20 upgrade for breaking changes/misconfigurations (standalone components, zoneless change detection, signals migration, lazy loading, ...

I need an expert to optimize a series of Customer-Experience (CX) reports currently built with a mix of technologies (SQL, Python, R, etc.). The current issues include slow performance during data refresh/filter operations and misaligned layouts. I’m looking for thorough enhancements to ensure seamless interactivity and better performance. Here’s what I need: - Analyze the current codebase to identify bottlenecks and formatting issues. - Refactor queries/scripts for faster refresh rates and perfectly aligned visuals. - Enhance the data set by validating sources, improving joins/calculations, and ensuring robust analysis-ready datasets. - Prefer experience with tools like Power BI, Tableau, Advanced Excel for report development. - Documentation of all updates made for easy futu...

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...

Ich betreibe zwei WordPress-Seiten – eine im Avada-, die andere im Divi-Theme – und möchte sie schrittweise optimieren. Dafür suche ich jemanden, der mich stundenweise und flexibel unterstützt, sobald neue Aufgaben anstehen. Kernaufgaben • Design-Anpassungen: Layouts überarbeiten, Farben und Schriften angleichen und bei Bedarf neue Bilder einfügen, damit beide Auftritte ein konsistentes Look-and-Feel erhalten. • SEO-Optimierung: Artikel mit Yoast optimieren, Meta-Daten nachpflegen und die interne Verlinkung verbessern, um die Sichtbarkeit in Suchmaschinen zu steigern. • Funktionsanpassungen: Performance-Tuning (Caching, Bildkomprimierung, Datenbank-Cleanup), damit die Seiten schneller laden und eine bessere Core-Web-Vitals-Bewertun...

I’m ready to turn years of hands-on experience in computer management, maintenance, and technical support into an engaging book that speaks directly to intermediate users—people who already know their way around a desktop or laptop but want to sharpen their skills and solve problems with confidence. The manuscript has to work in two environments: as a polished e-book (EPUB/Kindle-ready) and as a print-ready edition with proper trim, bleed, and interior layout. I need clear explanations, real-world examples, and practical walk-throughs that readers can follow on their own machines. Graphics, screenshots, and call-outs should be placed wherever they truly add value, not just for decoration. Core coverage I want to highlight: • Routine maintenance that actually preven...

I need an experienced UiPath developer who can take ownership of the entire automation lifecycle—from scoping and design through deployment in Orchestrator and day-to-day production support. My goal is to move several manual processes into stable, well-documented robots and keep them running smoothly as our business evolves. You will be responsible for: • Designing and developing UiPath workflows that follow best practices and are easy to maintain • Setting up assets, queues, triggers and schedules inside Orchestrator, then monitoring and tuning them for reliability and performance • Handling updates, error handling, bot versioning and troubleshooting so downtime stays minimal • Providing knowledge transfer and clear documentation so internal staff ca...

The interface will be a single Dashboard view populated with: • Graphs and charts • Indicators and gauges • Data tables I will supply the tag list and data source details; you handle the screen layout, bindings, and any scripting required inside GraphWorX. Please organise objects with clear naming conventions so future edits are straightforward, and optimise refresh rates to keep latency low without overloading the PLC or network. Deliverables • GraphWorX project file (.gwx) with all assets embedded • Any external script files if used • A brief hand-off no...

I have a series of Customer-Experience (CX) reports that were built by someone else and I’m running into two persistent headaches: the layouts never look quite right and the whole thing slows to a crawl whenever I refresh or filter the data. I’d like you to dive into the existing codebase—whatever language or mix of SQL, Python, R, or something else it was written in—and clean it up so the reports render cleanly, run quickly, and draw from a richer, better-structured data set. Here’s what I need from you: • Audit the current report logic and pinpoint the root causes of the formatting problems and performance issues. • Refactor or rewrite the underlying scripts/queries so visuals line up perfectly and refreshes complete in a reasonable time. &b...

My hotel site, , is already live on WordPress + Elementor; I only need it tightened up, not rebuilt. The “About Us” block is duplicated in the Elementor editor, so first you’ll delete the extra section. Next comes performance: I want WP Rocket installed, fully configured, and stress-tested against our ipms247 booking widget to be certain nothing breaks. All images should be compressed for fast web delivery (no need for ultra-high fidelity) and lazy-loaded where appropriate. SEO chores are limited but important: using RankMath, add FAQ schema as well as the correct Hotel/LocalBusiness structured data so Google picks up rich results. To show the work paid off, capture Google PageSpeed Insights scores before you start and once you finish; I expect a clear improvemen...

Over the past few days my Grafana + Prometheus stack has begun to churn far more CPU than usual, the web UI feels sluggish, and the graphs occasionally show empty gaps. I need a seasoned Grafana / Prometheus troubleshooter to dig in, pinpoint the bottleneck, and restore smooth, complete monitoring. Here is what I am after: • Diagnose and eliminate the recent CPU spike on the Grafana server (Ubuntu, Prometheus scraping multiple node-exporters). • Find out why some series disappear briefly and correct the root cause—whether that is scrape errors, query load, retention settings, or anything else you uncover. • Build a clean, focused dashboard that shows only the essentials I care about: CPU usage, Memory usage, Disk usage, Uptime, Bandwidth In/Out, and Network Speed...
