Rohan Kulkarni

“ Rohan Kulkarni is a Backend Engineer based in Bengaluru with 6 years of experience building high-performance backend services in Go and Rust. He has worked on systems that handle millions of requests per day, payment processing infrastructure, real-time data pipelines, and API gateways where language choice and deployment configuration have a measurable impact on latency and infrastructure cost. Rohan has deployed Go and Rust services across AWS, GCP, Fly.io, and bare metal, and has a detailed understanding of where each deployment environment helps or hinders compiled language applications. He has written internal benchmarking tooling, optimised cold start behaviour in containerised Go services, and pushed Rust async services using Tokio to sub-millisecond p99 latencies in production. At Kuberns, Rohan writes deployment guides for Go and Rust developers, a growing category that most PaaS documentation leaves underserved. His content focuses on the specifics: binary builds, container image sizing, environment configuration, and the performance trade-offs that matter when you have chosen a systems language precisely because performance matters. ”
