Freelance PHP/Laravel Developer · Site Optimization · Server Setup & Monitoring · Upwork · Fiverr.

Hi! I’m Zia Uddin Robin, a computer-science graduate from Bangladesh and a full-time freelance PHP/Laravel developer. For over a decade I’ve been shipping production PHP — Symfony, Laravel, Slim, CodeIgniter, WordPress — with MySQL/MariaDB, Postgres and Redis behind it. These days my workflow is AI-augmented: I pair hand-written code with GitHub Copilot, Claude and ChatGPT to deliver features, fix bugs and rescue ongoing projects much faster — while still reading, testing and reviewing every line myself.

I build & customize e-commerce stores, restaurant ordering systems, business websites and REST APIs for mobile apps, including heavy customization of CodeCanyon scripts (ViserHotel, NexoPOS, Shofy and similar). I also optimize existing websites for real-world speed and search — Core Web Vitals (LCP / INP / CLS), responsive image pipelines (AVIF + WebP), font & CSS budget cuts, structured data, sitemap automation and internal linking.

On the operations side I handle Linux server setup & DevOps: Ubuntu/Debian VPS provisioning, Caddy, Nginx or Apache with PHP-FPM, automated TLS, Cloudflare in front, firewall & SSH hardening, scheduled backups, Git-based deploys and zero-downtime release scripts — followed by ongoing monitoring & alerting (uptime, response time, CPU/memory/disk, log rotation, error tracking) so the sites I ship stay healthy long after launch.

AI-assisted content creation is part of what I deliver too: long-form articles, service / landing pages and meta tags drafted with AI and refined by hand for accuracy and search performance.

I’m active on Upwork and Fiverr, mentor junior developers, and write notes on what I learn at nzian.xyz/blog. In my spare time I travel and shoot mobile photography.

Founder & CEO, Four B Online, Chittagong, Bangladesh
