About Me

Hello, I'm Atharv

I'm a Full Stack Engineer from Pune, India, specializing in building high-performance, scalable applications with the MERN/PERN stack and React Native. I'm passionate about backend development and understanding how technology works from the ground up, which led me to architect and build Reiatsu - a zero-dependency TypeScript web framework.

Currently working at SmartScripts Pvt. Ltd., I build production applications and mobile apps. I started my coding journey in January 2021 and turned professional in March 2024 - 4+ years of hands-on experience building real-world applications.

I believe in building in public and sharing my learnings. My projects span from frameworks to mobile apps, all built with the philosophy of understanding fundamentals and creating from scratch.

When I'm not coding, you can find me watching movies, diving into a new anime series, or exploring the world around me with my girlfriend. I believe that diverse interests fuel creativity in problem-solving.
