I'm Nayan Rathod, a software engineer and systems architect who builds from first principles. My flagship work includes Doo, a Rust-based compiled language with an LLVM backend, and DooCloud, a spec-driven backend platform that auto-generates, migrates, and deploys production backends on GCP. I design end-to-end toolchains, production-grade libraries, and scalable cloud infrastructure that handles real workloads. Beyond these, I bring deep experience across Go, Node.js, React, Next.js, and Flutter; microservices with gRPC and Kafka; real-time systems with WebSockets; and cloud deployments on AWS and GCP with CI/CD via GitHub Actions. I enjoy shipping impactful tooling and taking a product from architecture to production as a solo engineer.…I'm Nayan Rathod, a software engineer and systems architect who builds from first principles.
