Frequently asked questions.

Hiring a software engineer in Bangladesh or across South Asia? Here is what people usually want to know.

Who are you?+

I am Zahin Afsar, a full-stack software engineer based in Bangladesh. I specialize in TypeScript, React, Next.js, and Node.js, and I build performant, accessible web products for startups and businesses across Bangladesh, South Asia, and worldwide.

Are you available to work with clients outside Bangladesh, across South Asia and beyond?+

I work remotely with startups and teams across South Asia and worldwide, collaborating across time zones and delivering resilient, well-tested TypeScript codebases on tight deadlines.

Do you provide the best value-for-money software?+

Yes, Because I live in Bangladesh, my cost of living is far lower than in Europe or North America, so I can charge much less than a Western engineer for the same work. You still get senior-level, full-stack engineering focused on conversion, performance, and maintainability, just at South Asian rates.

Are you specialized in particular technologies?+

I focus on Next.js, React, TypeScript, Node.js, PostgreSQL, GraphQL, and Shopify, with a strong emphasis on frontend performance, accessibility, and clean, type-safe architecture.
