About

I’m an experienced backend engineer with over six years of experience designing and delivering scalable web applications and APIs. Most recently at Nes.tech, I built microservices for a global payment gateway. This setup supported multi-currency and crypto transactions, reduced latency by 40%, and maintained 99.95% uptime while handling over 20,000 daily transactions. As Director of Engineering at Thinks Pvt Ltd, I led teams in building ride-hailing platforms and managed the complete project delivery. This work improved performance and developer speed across the board. I enjoy solving real-world problems through clean code, effective system design, and cloud-based deployments using AWS, Docker, and CI/CD. Currently, I’m expanding my knowledge in Generative AI with a PG Diploma from IIIT-Bangalore. My goal is to integrate AI-focused solutions into backend architectures. Feel free to reach out if you’re interested in building secure, high-performing, AI-driven products!
