8+ years building WordPress at the code level.
I'm Saddam Hossen — a WordPress developer from Jamalpur, Bangladesh. I work in PHP, hooks, $wpdb, and the REST API. Not page builders.
From curious learner to senior developer
I started with WordPress around 2017 — not building sites, but trying to understand how WordPress actually worked underneath. Hooks, actions, filters, the template hierarchy, the rewrite engine, the options API. That curiosity became the foundation of everything I do now.
Over the next few years I went from front-end work to full plugin development. The turning point was a project where I built a custom bulk import system that reduced a nonprofit client's manual data entry from 100+ hours down to 2 hours. That's when I understood what this work is really about — not shipping code, but solving real business problems through code.
Since then I've worked with agencies in Canada and Australia, published open-source plugins on WordPress.org, built WooCommerce systems processing thousands of orders, and taken WooCommerce sites from PageSpeed 42 to 91. I'm currently building SiteProof AI — an automated WordPress audit and remediation tool using Claude 3.5 Sonnet and MCP.
On Upwork I'm Top Rated with 100% Job Success and every single review is 5 stars. I'm open to full-time remote roles and long-term agency partnerships.
