My site is loading too slowly and it’s hurting conversions. I need a specialist who can dig into the underlying causes and cut load times dramatically—page-load speed is the single metric I care about most right now. Here’s how I picture the engagement: • Benchmark the current performance (desktop and mobile) with tools such as Google PageSpeed Insights, Lighthouse, or GTmetrix. • Implement best-practice fixes—minification of CSS/JS, critical-path rendering, browser caching, server-side or plugin-based page caching, image compression/next-gen formats, lazy loading, and anything else that meaningfully shaves off seconds. • Provide a brief, clear report that shows before-and-after numbers and outlines what was changed, so I can maintain the gains g...

I need a dependable partner who can both keep my existing salon-at-home mobile app running smoothly year-round and drive the next wave of improvements. The engagement will cover two parallel tracks: 1. Annual Maintenance Contract • Proactive monitoring, quick bug fixing, security patching and version updates • Monthly health reports and a clear escalation path for any critical issues • Store-listing support whenever OS or policy changes demand it 2. Product Enhancement Roadmap • New features that extend booking, stylist management and payment capabilities • A refreshed, more intuitive user interface that feels premium and effortless for clients and professionals alike • Performance tuning to shorten load times, reduce crashes ...

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...
