I'm Nafish
Ahmed.

I'm a Senior Software Developer from India. I build scalable web applications, backend systems, and integrations that solve real problems. I care about clean code, thoughtful architecture, and shipping things that work.

I've spent the last few years working across the full stack — from crafting responsive UIs to engineering high-performance APIs and complex third-party integrations. I thrive in environments where the problems are hard and the standards are high.
