My site has started throwing form-submission errors and overall page speed has dipped, so I need a focused cleanup. The first priority is to get every form submitting reliably again. While you’re inside the form logic, please switch the date field to the new format I’ll supply, introduce a couple of new data fields, and strip out any obsolete ones I point out. Loading time is the next pain point. I’m looking for pragmatic optimisation—compressing heavy assets, tweaking queries, improving caching—whatever brings the site back to a snappy response without a full rebuild. Finally, the WhatsApp button needs a quick tweak: change the pre-filled message text so that it pulls a short template I’ll provide. The button’s position and core functionality ca...

WordPress VPS Performance Issue We have a VPS server with several WordPress websites. The server is not overloaded (CPU/RAM usage is normal), but the websites are loading very slowly and lagging. We need an experienced freelancer to identify the cause and fix the issue. Server and WordPress optimization may be required. Please contact us with your experience and estimated time to resolve the problem.

I’m a full-time developer working directly in a live Guidewire ClaimCenter environment and I keep running into questions that slow me down. Most of my challenges revolve around writing efficient, optimized Gosu code that still respects ClaimCenter conventions and integrates cleanly with the existing services we already have in place. I have several code-quality and optimization tools running in the pipeline, so guidance will need to mesh with those rather than start from scratch. What I need is an ongoing, hands-on mentorship: quick walkthroughs when a production incident pops up, deeper sessions where we dissect the current implementation, and regular checkpoints to review the efficiency of new logic before it reaches production. You’ll also help me confirm that documents gen...

My desktop has been running noticeably slower for a few weeks, right after I installed some new software. I’d like a seasoned PC technician to jump in remotely, diagnose the exact cause, and restore normal speed without losing any of my data or settings. Key details you should know: • Current issue: Slow performance • Onset: Began a few weeks ago • Recent change: Installed new software prior to the slowdown What I need from you: • Perform a full system health check (CPU, RAM, disk, background processes) • Identify and remove unnecessary startup programs or bloatware • Verify the recently installed software isn’t hogging resources or conflicting with drivers • Clear temporary files and optimize system settings for better responsiveness •...

I work full-time on a live Guidewire ClaimCenter implementation and regularly handle production incidents—everything from mis-routed documents to integration hiccups. While I can usually patch issues, I want to move beyond quick fixes and truly master the platform. My immediate focus is on Coding best practices in Gosu. I often find myself guessing when it comes to structuring classes, optimizing performance, or leveraging the framework’s more powerful constructs. To sharpen my skills, I need long-term, hands-on mentoring that covers: • Advanced features and techniques in Gosu (refactoring pattern code, metaprogramming, performance tuning, and testability) During our sessions you’ll walk me through real tickets, explain why a particular solution works in ClaimCent...

The core of my pets-services platform is already running on C#, ASP.NET Core and SQL Server, but only part of the roadmap is complete. I need a developer who can dive into the existing repository, understand what’s been built so far and then work alongside me, sprint by sprint, until we launch. and after we launch stay with me to develop it more. Where things stand • Current status: partially developed. Key models, some controllers and basic pages are live, but several workflows still stop at stubs or placeholders. • Guidelines: I have an architecture outline, UX wireframes and a list of required endpoints; however, I’m open to your recommendations on best practices, performance tuning, and UI polish. What you’ll be picking up – Clean up and extend...

I need a cross-device video player built for Android TV, tablets, and phones, replicating the complete experience of MX Player. The core must include smooth subtitle rendering (multiple formats, online/offline), responsive gesture-based controls for brightness, volume, and seeking, plus reliable hardware acceleration so even high-bit-rate files play without stutter. Beyond those headline items, I expect the familiar MX staples—playlist handling, aspect-ratio toggles, background playback, and on-screen codec info—to feel just as polished on all three form factors. A single code-base that detects screen class and adapts its UI is ideal; Jetpack Compose or standard XML layouts are both fine as long as Leanback guidelines are respected on TV. Because I’d like to move quickl...

My Shopify store is ready for a performance and accessibility tune-up focused primarily on the product pages. I need an experienced developer who can dive into the theme code, installed apps, and page assets to squeeze out every millisecond of speed while making the site friendlier to all users. Performance goals – Audit all scripts and apps loaded on product pages, keeping only what is essential and rewriting or deferring anything that slows First Contentful Paint. – Re-compress and properly size images, SVGs, and other media across the store. – Address any Core Web Vitals warnings flagged in Lighthouse or Google PageSpeed Insights. Accessibility upgrades The most pressing fixes are on product pages, specifically: • Correct, programmatic form labels for ...

My Ubuntu-based server runs Nginx as both the webserver and an HTTP reverse proxy. Despite average utilisation staying below 50 %, I keep running into three intermittent problems: • the nginx service suddenly stops, • the whole OS occasionally freezes, and • some requests return 500 errors even though the upstream application is healthy. What I need from you is a full-scope diagnosis, clear explanation of the root cause(s), and concrete fixes. That will likely involve: • auditing current nginx and systemd settings (nginx ‑T, unit files, , etc.), • analysing kernel, journal and dmesg logs for memory, I/O or cgroup problems, • stress-testing and reproducing the 500 responses, • tuning worker processes, buffers, time-outs and any OS limit...

I’ve just finalised our new brand, positioning and messaging with an agency and now need that work translated into a polished online presence. Because we’re a boutique B2B cyber-risk management firm, the site has to project a professional, corporate feel—clean lines, restrained colour palette, crisp typography and flawless responsiveness. Scope of the build • Incorporate all updated copy and visuals • Create a dedicated case-study area where each story features client testimonials, a clear problem–solution breakdown and measurable results. • Build a resource hub that supports downloadable documents and a searchable article library, with an easy back-end for future uploads. • Add an events & webinars section my team can update wi...

My WordPress site works, but it still feels sluggish. I’d like a specialist to focus on improving raw loading speed, with particular attention on the homepage and key product pages where most visitors land and convert. If you spot additional quick wins elsewhere—say, inside a long-tail blog post—that’s a bonus, yet the brief is firmly anchored on the pages that make the business money. Here’s what I expect the engagement to cover: • Run an initial performance audit (Core Web Vitals, GTmetrix, Lighthouse or similar) to create a clear before-and-after benchmark. • Optimise code, assets and queries: efficient caching, image compression, script deferral, tidy database tables, and any necessary theme or child-theme tweaks. • Review plugins only...

I run a coupon and deals platform and I’m ready for a complete SEO refresh aimed squarely at higher Google rankings. The homepage and every category page are my top priority, but I want best-practice tactics applied across the entire site so users and search engines both love it. Here’s the outcome I’m after: faster load times, cleaner code, rock-solid Core Web Vitals, and perfectly crafted meta data that lifts my pages in Google’s results. To get there you’ll tackle on-page fixes, technical clean-ups, and performance wins in one cohesive pass. Key deliverables • Comprehensive on-page optimisation, including keyword-aligned titles, meta descriptions and image alt text • Favicon update and any required schema markup so rich snippets can surface ...

I have the full Knight Online 2383 client source running on DirectX 9 and need it modernised to DirectX 11. The server is stable—only the rendering layer must change—so your work will focus on the graphics pipeline, shader set-up, device management and all HLSL migrations. What must remain untouched is critical: • User Interface (UI) elements • Game mechanics • In-game animations On the optimisation side I’m targeting: • Noticeable frame-rate gains, especially in crowded zones • Lower overall memory footprint • Faster initial and zone-change load times You will be working in C++ with the existing codebase; all shaders are available and simply need rewriting or refactoring for DX11. I expect clean, well-commented commits so ...

I run a small, private Survival Minecraft world that usually tops out at ten friends during peak evenings. I’d like someone to take over the technical and community-facing chores so I can focus on simply playing. The immediate priorities are: • Plugin setup and upkeep – install, configure, and keep updated essential Paper/Spigot plugins (economy, land-claim, grief prevention, permissions, chat, and any quality-of-life add-ons we agree on). • Performance tuning – optimise the JVM flags, Paper config, and hardware allocation to keep TPS rock-solid even when redstone farms or exploration spike our tick load. • Light moderation – help enforce basic rules, roll back griefs with CoreProtect-style tools, and maintain a friendly chat atmosphere; no heav...

I’ve hit a wall fine-tuning my Steam Deck for Pokémon and need a technically minded pair of hands to finish what I started. Here’s where I’m stuck: • PKHeX is still on an old build. I’d like the newest release installed, fully working with the saves I already have. • My Pokémon Fire Red ROM refuses to open in PKhex the game itself can be played and do a in game save but something in the Deck’s setup is off or PKhex or Mgba • Generations 8-9—including Let’s Go Pikachu and Shining Pearl—stutter, drop frames, and occasionally hard-crash. Since that happened, the Nintendo Switch app on the Deck won’t boot any game at all. What I need from you is a clean, end-to-end fix: update PKHeX, get Fire Red recognised a...

I need my existing Flutter mobile app compiled and adjusted for the web so that more people can reach it from a browser. The core feature that absolutely must work flawlessly online is the real-time data synchronization already built into the mobile build; everything else can follow once that is solid. The compiled web build has to run smoothly in Chrome at launch. If it ends up working on Firefox or Safari as a by-product that’s great, but Chrome compatibility comes first. You will receive the current codebase, Firebase back-end credentials, and the design assets. Your job is to: • refactor or add any platform-specific logic needed for Flutter Web • ensure all existing sync flows behave identically in the browser • optimise loading times and adjust responsive l...

Saya membutuhkan bantuan untuk meningkatkan performa motor saya, khususnya pada sistem pembuangannya. Fokusnya sederhana: hasil nyata tanpa penjelasan bertele-tele. Apa yang saya butuhkan: • Analisis singkat kondisi knalpot saat ini dan potensi sumbatan atau pembatas aliran gas buang. • Rekomendasi komponen after-market yang legal dan cocok dengan mesin (mis. header, muffler, atau packing baru) lengkap dengan perkiraan harga. • Pemasangan komponen secara rapi, termasuk pengecekan back-pressure agar tenaga tidak drop. • Pengujian cepat—misalnya dyno run singkat atau test ride terukur—untuk memastikan ada kenaikan performa yang terasa. Kriteria keberhasilan: – Tarikan lebih responsif dan suara tetap dalam batas wajar. – Tidak muncul error...

Baldur’s Gate 3 keeps crashing on me mid-game and based on my researches, everything points to the graphics card. I’m running an NVIDIA GPU, RTX 4050, with the latest drivers already installed, so driver updates aren’t the issue. The game with the Larian launcher sometimes doesn't launch properly; the problem also shows up once I’m actually playing. I need someone who can dig into GPU-related crashes—review logs, diagnose conflicts, tweak in-game or control-panel settings, or apply any known hot-fixes—until the game stays stable. A clean, repeatable solution is the goal; I don’t want a workaround that still risks random lock-ups a few hours later. Deliverables • Pinpoint the root cause of the gameplay crashes • Apply or outli...

My site feels sluggish, images take too long to appear, and I am running into storage-related limits that keep new photos from uploading smoothly. I want the whole experience to feel snappy and hassle-free again. The core of this job is performance tuning. I need three concrete upgrades: • Optimize images so every picture is compressed without noticeable quality loss • Minimize code and scripts—strip unused CSS/JS, combine and minify what stays • Improve server performance through smarter caching, database clean-up, and any other proven tweaks you recommend Alongside the speed work, please diagnose and clear the issues that are blocking or slowing photo uploads and eating up server space. Once you are done, I expect visibly faster page loads on both mobile and...

Hello, I have a website under wordpress, and the task is about improving the score of "Performances" in mobile section of google speed insights. The actual score is 65 points and it need to be plus of 90 points. I'm using caching in server level with CDN of the hoster, with a default cache plugin installed by the hosting privider too. Note that you have to work with the actual structure and not use cloudflare for example, all things are working smoothly with the installed structure. All metrics are ok in desktop (google speed insights) and in mobile too, except the "performances" score in mobile that you need to fix. My budget for that task is 10 USD. Thank you.

I need an expert web developer to build a brand new, ultra-lightweight website using clean HTML, CSS, and minimal JavaScript. My current website is too slow. I want this new site to be highly optimized for Local SEO and integrated with AI features for maximum performance.

I need a hands-on web developer with 2–3 years of solid, day-to-day coding experience who is completely comfortable building and refining React applications. You’ll jump straight into an existing code-base, ship new features, polish UI/UX, and fix the odd regression while talking directly with me and, at times, end clients. Because many conversations happen live over video or Slack, clear, confident communication in English at a strong B2 to C2 level is a must; you should feel at ease explaining technical trade-offs to non-technical stakeholders and gathering requirements in real time. Our stack centres on React, so depth there matters more than breadth in other frameworks. Clean component architecture, state management know-how (Context, Redux, or hooks-only patterns), and ...
