Hasan Tezcan
Software Engineer
I build fast, maintainable web products and developer tools. I work on large-scale ecommerce experiences across multiple markets, mostly around frontend architecture, checkout, internationalization, CI/CD, and internal tooling. Outside work, I write short technical notes and build small products that solve annoying problems.
