I have a fresh server waiting for you to connect and install an open-source hypervisor—VirtualBox is my chosen platform. Once VirtualBox is in place, I need twenty fully functional desktop machines, 10 running Arch Linux and the other 10 Linux Mint. Each desktop must sit in its own isolated VM. Key requirements • Shared-folder integration between host and guest so I can move files back and forth effortlessly. • Reliable USB pass-through so attached devices appear inside the VM just as if they were local. • RDP and VNC configured on both guests for smooth, encrypted remote access. Please tune the settings for good performance over typical broadband connections. Beyond the basics, make sure the guest additions (or equivalent) are installed, networking is bridged f...

I’m setting up a Minecraft server focused exclusively on a frantic Free-For-All experience. The core request is simple yet demanding: one server, one game mode—FFA—running on custom-built terrain that feels truly unstable. Think floating islands, collapsing bridges, shifting hazards; the map itself should keep every player guessing rather than follow a neat fantasy, modern, or medieval style. To make this happen, I need you to: • Spin up a stable Paper/Spigot instance tuned for PvP. • Design and import at least two distinct “unstable” arenas (≈ 200 × 200 blocks or larger) that funnel players into constant combat while preventing easy escapes. • Configure essential plugins—scoreboard, random spawn/kits, anti-cheat, auto-rese...

My WooCommerce store on a shared SiteGround plan keeps hitting their resource ceiling. SiteGround automatically suspends the site several times a day and their logs show waves of unfinished SQL queries piling up until new requests tip us over the limit. As a result I’m facing frequent downtime, very high CPU usage and painfully slow page loads that are costing sales. I need someone who knows WordPress, WooCommerce and SiteGround’s architecture inside-out to: • trace and fix the slow queries or loops that are stacking up • review theme, plugin and custom-code interactions that might be spawning excess calls • configure or fine-tune caching (SiteGround Optimizer, object cache, browser cache) so requests are served faster instead of re-querying the database ...

I need help breathing new life into an existing product that is suffering on three fronts: it loads slowly, the interface feels clunky, and several core features occasionally break or behave unpredictably. My main objective is to improve—not rebuild—the current solution, so I want a developer who can dive into the codebase, spot the root causes, and roll out solid fixes without disrupting day-to-day use. The work centres on: • Performance: shorten load times and remove any bottlenecks. • User interface: polish layouts, resolve visual glitches, and ensure consistent styling and behaviour across screens. • Functionality: track down logic errors, eliminate crashes, and make sure every advertised feature works reliably. I’ll supply repository access, stag...

My WooCommerce store has become painfully sluggish: pages hang for seconds, the site drops offline unexpectedly, and every so often it throws fatal errors that crash the whole shop. The core goal is to restore fast, stable performance without breaking any storefront features. What I’m facing • Slow loading times • Frequent downtime • Intermittent errors or outright crashes The build is a standard WordPress + WooCommerce setup with just a few third-party plugins and a fairly lightweight theme. I suspect a mix of plugin conflicts, database bloat, and missing caching layers, but I need a systematic diagnosis rather than guesswork. Scope of work 1. Audit – run a full performance scan, profile slow queries, and review the active plugins/theme stack for co...

I run a large WordPress installation—about 80,000 pages—and, while I’m comfortable with server administration at an advanced level, the stack is hitting its limits. Under heavy traffic and aggressive crawler activity we see: • 500 errors under load • Indirect/server errors affecting crawlers • Slow performance under high traffic I need a LiteSpeed specialist to dive in and eliminate these issues. Scope of work 1. Audit and benchmark my current setup on CyberPanel, focusing on LiteSpeed Web Server, Redis, and MariaDB. 2.

Our main database is already running on PostgreSQL 13 (anything in the “12.x or higher” family), and I need an experienced DBA to step in and tighten two things: First, Database optimization. The work includes reviewing current configuration parameters, checking execution plans, tuning indexes, and suggesting any schema changes that will noticeably reduce latency under peak load. If extensions (pg_stat_statements, auto_explain, etc.) should be enabled or configuration values (shared_buffers, work_mem, effective_cache_size and friends) adjusted, please make those recommendations backed by data. Second, Backup and recovery. I want a clear, scripted process—preferably with pg_dump and/or a modern tool such as pgBackRest or Barman—that covers daily backups, point-in-t...

My surf-activity website is ranking lower than it should, and I have narrowed the issue down to technical SEO. I want a specialist who can audit the codebase, identify the speed bottlenecks, and implement clean, measurable fixes that move the site up in Google. Core focus • Page-load performance: compress images, optimise critical CSS/JS, fine-tune server and caching settings, and ensure Core Web Vitals all show “good” in PageSpeed Insights and Lighthouse.

A concise changelog of every optimisation applied. 3. Confirmation that there are no new console errors, broken link...

Our production systems run on a dedicated PostgreSQL database server that needs ongoing, professional management to keep performance high and downtime at zero. I need an experienced PostgreSQL administrator to take charge of routine upkeep, monitoring, and rapid incident response so the team can stay focused on product development. Scope of work You’ll handle version updates, configure and verify automated backups, watch key metrics, fine-tune queries and indexes when bottlenecks appear, and strengthen security by keeping roles, permissions, and network rules tight. The server is Linux-based and accessed via SSH; fluency with psql, pgAdmin, and common monitoring stacks (Prometheus, Grafana, or similar) will make the job straightforward. Deliverables • Initial health audit ...

I need my WordPress website pushed to the absolute edge of performance. My target is a 99–100 score on Google PageSpeed Insights (mobile and desktop) and a perfect 100 on the Lighthouse SEO audit. I’m happy to give you full admin and hosting access so you can dig into caching, code minification, image compression, server-level tweaks—whatever you think best. Here’s how I’ll know the job is done: • You send before-and-after PageSpeed Insights and Lighthouse screenshots showing the requested scores. • All visual and functional elements remain intact; no layout shifts or broken scripts. • You document the exact changes (plugins enabled, lines of code edited, server settings adjusted) so I can maintain the gains myself. If you’ve alread...

Title: Speed Optimization and Completion of Forex Non-Print Quant Research Program I have an existing Windows-based, three-part quantitative research program designed to discover and validate trading strategies for OANDA forex markets.

A fresh AlmaLinux 10 server is waiting to be transformed into a production-ready shared-hosting node. The work starts with clean installs of cPanel/WHM, LiteSpeed Web Server, and CloudLinux, followed by enabling WHM’s reseller features and deploying WHMCS for automated billing and provisioning.
