01. About Me

I'm a passionate Software Engineer with expertise in building scalable, enterprise-grade applications. Currently working at Paytm, where I architect and deliver high-performance systems processing millions of events monthly.

My journey in tech started with a B.Tech degree and was further strengthened through intensive training at Masai School. I specialize in designing microservices architectures, implementing event-driven systems, and optimizing application performance.

I thrive on solving complex problems and building systems that make a real impact. Whether it's reducing API response times by 65% or architecting fault-tolerant workflows, I'm always eager to push the boundaries of what's possible.
