I'm Mahamudul Hasan Rubel — a Senior Software Engineer with over 12 years of experience building web applications, SaaS platforms, and WordPress products. I started coding at 16, driven by curiosity and a desire to build things that work.
Today I lead engineering at JoulesLabs, where I architect and ship ReviewX v2 — a SaaS WooCommerce reviews platform with 10,000+ active users. I care deeply about performance, clean architecture, and mentoring junior engineers.
When I'm not writing code, I'm teaching web development, contributing to open source, or building independent tools like CodeToolStack. I believe the best engineers are also great communicators and team players.
Built my first website at 16. Discovered WordPress and fell in love with the web.
Sold a WordPress contact-form plugin on CodeCanyon. 200+ copies sold. Proof that code can generate income.
Launched freelance career on Upwork. Achieved Top Rated status within 8 months. Delivered 50+ projects across 12 countries.
Joined as Lead WordPress Developer. Scaled the site to 5M+ monthly users. Led a team of 4.
Promoted to Senior Engineer & Team Lead. Architected ReviewX v2 from ground up. Grew it to 10K+ users.
Launched CodeToolStack (270+ dev tools) independently. Built RactStudio.com on Next.js 16 + Cloudflare Workers.
Prefer small, working releases over big-bang launches. Real users reveal what specs cannot.
Every millisecond matters. Lighthouse scores, query times, and bundle sizes are first-class citizens.
Clear, readable code is documentation. I write for the next engineer, not the compiler.
A rising tide lifts all boats. Investing in junior engineers multiplies the entire team's output.
I teach web development to students in my community. I run informal workshops covering HTML, CSS, JavaScript, and WordPress — helping people start their tech careers. I've taught 30+ students, several of whom now work as professional developers.
