Hi, I'm Moyez — a Software Engineer from Kolkata, India with a genuine curiosity for the deeper side of Computer Science. I don't just use tools, I want to understand how they work under the hood.
Over the past 2.5 years, I've built end-to-end software that works well and looks even better. I care about design and user experience as much as I care about the code behind it — good software should feel effortless to use.
When I'm not coding, you'll find me reading or at the gym. I like building things, staying sharp, and never sitting still for too long.
Featured writing first, then the newest notes on engineering, design, and building useful products.
