About
Me
I'm Rashed — eight years building mobile and web products end to end: architecture, native modules, real-time infrastructure, performance tuning, security hardening, and the store release that puts it in someone's hands.
My work lives in the parts most engineers avoid. I've built one-to-one chat systems on WebSockets, hardened an enterprise telecom app with SSL pinning, root detection, and SSO, and wired up multiple payment SDKs behind a single checkout. Right now I'm building a voice AI platform that streams audio, runs speech-to-text, and answers back with LLM-generated speech — in Bangla and English.
I think in products, not features. At ShellBeeHaken I joined KriyaKarak — a marketplace where Bangladesh's photographers, makeup artists, designers, and musicians find clients — as a senior React Native engineer, and a year later was promoted to lead its team. It's live on both the App Store and Google Play. Before that at Bdtask I shipped apps for clients in Bangladesh, Sweden, and the telecom sector, each one a different domain.
I care about craft at every layer: clean, structured codebases, smooth animated UI, Japan-grade UX standards, and pipelines that turn a merge into a store build. The goal is always the same — software that works for people who never think about software.
Make it right. Make it fast.”
Two companies, six products, three markets — a timeline of the real problems I solved and the technical depth I earned along the way.
