Jubayer Al Mamun
About
I'm a software engineer based in Dhaka, Bangladesh, mostly self-taught, currently working at WeCycle. I've spent the last few years shipping production software end to end: services, schemas, and interfaces.
A little more
I started programming in 2020, by accident, mostly. I opened a stylesheet, and never really stopped. Since then I've shipped products at small startups, contributed to open source, and helped a handful of teams move faster without breaking things.
My work tends toward simple, fast, and considered. I'm at my best when I can own a problem from data model to interaction detail.
