About me

Developer by skill, Founder by choice.

I'm Sayedul Islam — a self-taught web developer from Bangladesh who started coding at around age 12. I don't just write code to build websites. I write code to build products that solve real problems.

I founded SA Coder, a SaaS platform built for developers. It's not just a project — it's a business I'm actively growing. Being 17 doesn't slow me down. It pushes me to move faster.

My stack is PHP, MySQL, HTML, CSS, and vanilla JS. I keep things lean, fast, and ship-ready. No bloat. No excuses.

"I don't wait to grow up. I build while growing up."

My story

From first line of code to Founder

2019

First Line of Code

Wrote my first HTML file. Didn't know what I was doing — but I was hooked immediately. Started learning on my own, no teachers, no courses — just browser + curiosity.

2020-21

Getting Serious

Moved from HTML to CSS to JavaScript. Built my first real websites. Discovered PHP and fell in love with backend logic. Realized I didn't just want to code — I wanted to build things.

2022

First Real Projects

Started building projects for real use cases. Learned MySQL, started thinking about databases and systems. Shipped my first dynamic PHP+MySQL web app.

2023

The Founder Mindset

Stopped thinking like a freelancer. Started thinking like a founder. Started planning SA Coder — not as a side project, but as a real business.

2024-25

SA Coder Goes Live

Launched SA Coder — a SaaS platform for developers. Still building, still growing. Doing all of this at 17, from Bangladesh, self-taught.

Why I still choose PHP over Node.js

Everyone wants to convince you to switch stacks. Here's why PHP + MySQL is still my weapon of choice for shipping fast.
