About

I am a Backend Engineer at Tamara with over 3 years of industry experience, specializing in building highly scalable, performant, and reliable backend systems. My expertise lies in designing robust microservices using technologies like Spring Boot, REST APIs, gRPC, Kafka, Redis, and MySQL. Previously, I worked at Paytm as part of the OAuth team, where I led the development and maintenance of critical authentication and authorization flows used by millions of users. I handled systems with throughput of up to 50,000 transactions per second (TPS), ensuring secure and seamless login and signup experiences at scale. Beyond core backend development, I have hands-on experience with monitoring and observability tools such as Grafana, Kibana, and Loki, enabling me to proactively monitor system health, analyze performance, and troubleshoot production issues effectively. I hold a B.E. in Computer Science and Engineering from PEC Chandigarh, where I graduated with a CGPA of 7.98. I bring a strong foundation in computer science principles along with real-world experience in delivering production-grade backend solutions. Always eager to learn and grow, I’m passionate about building systems that scale and make an impact. Feel free to connect or reach out if you'd like to know more or collaborate.
