Hi, my name is
Joynal Abedin.
I build things for the web.
I'm a software engineer specializing in building exceptional digital experiences. Currently, I'm focused on building accessible, human-centered products.
01. About Me
Hello! My name is Joynal and I enjoy creating things that live on the internet. My interest in web development started back in 2012 when I decided to try editing custom Tumblr themes — turns out hacking together HTML & CSS was fun!
Fast-forward to today, and I’ve had the privilege of working at an advertising tech company, a recruitment automation platform, and a smart energy system. My main focus these days is building accessible, inclusive products and digital experiences for a variety of clients.
