Software engineer
I'm Md. Zahin Afsar — a software engineer from Bangladesh, building performant, accessible products with JavaScript & TypeScript.
For the past three years I've led frontend work across Shopify integrations, peer-to-peer marketplaces, and internal dashboards — turning fuzzy requirements into resilient TypeScript codebases while finishing my B.Sc. in CSE at Green University of Bangladesh, and looking to take on bigger, more challenging problems as a software engineer.
