About Utkarsh Yadav

I’m a backend engineer with 3+ years of experience building scalable, high-performance systems using Golang and modern cloud-native technologies. I specialize in designing distributed architectures, developing robust microservices, and optimizing backend performance for real-world, high-traffic applications. At Razorpay, I worked on the One Click Checkout product, where I led efforts to rearchitect core payment flows, introduced concurrent processing using Go routines, and implemented async workflows with Kafka and SQS, resulting in major performance gains (e.g, 75% faster load times). I also contributed to service decomposition, API reliability, and integrations with wallets and third-party services. I’m deeply familiar with gRPC, Kafka, Docker, Kubernetes, AWS, and observability best practices, and I enjoy solving complex system-level problems with clean, idiomatic Go code. Whether it's building fault-tolerant services, optimizing DB queries, or automating workflows, I focus on writing scalable, production-ready backend solutions that make a tangible impact.
