Six years of hands-on React/Next work is essential because I need somebody who recognises anti-patterns instantly and can move from audit to optimisation without a long ramp-up. The stack also touches SCSS, REST endpoints, Jest tests and a bit of Redis-backed caching, so fluency there is useful even though the core focus stays on the browser side. Key things I’m counting on you to handle • Deep bundle analysis, code-splitting, tree-shaking and any other techniques that cut initial download size • Smart use of features—dynamic imports, image optimisation, prefetching and edge middlwares&md...

The stack is a standard WordPress install; at the moment I’m not sure whether any caching plugin is active, so part of the job is to confirm what’s running and, if necessary, configure or replace it with a better option. You’re free to use proven tools such as WP-Rocket, LiteSpeed Cache, W3 Total Cache, Redis object caching, query monitors, or any other technique you judge effective, provided the final result is stable and compatible with the existing theme and plugins. Please deliver: • A brief before-and-after performance report (PageSpeed Insights or GTmetrix) that highlights the improvements in loading time, Time to First Byte, and database query count. &bul...

Hi, I’m planning to move all my apps and websites from Cloudways to Hetzner and would like your help setting this up. We’ll need 2 servers on Hetzner: Server 1 (apps): CPX31 (8GB RAM, 4 vCPU) Server 2 (websites): CPX21 (4GB RAM, 3 vCPU) Location: Ashburn, US OS: Ubuntu 22.04 Install CyberPanel (OpenLiteSpeed) on both with Redis and Memcached enabled. Apps server will host all CodeIgniter applications Web server will host ~10 websites and landing pages Move DNS to Cloudflare for SSL, CDN, and caching. Scope includes: * Full server setup and hardening * Migrating all apps and websites * Database setup and import * Cron jobs configuration * Performance optimization (LiteSpeed cache, PHP tuning) * Testing before going live
