Hi 👋 I'm Vishnu

Technical Lead | Backend Engineer | Distributed Systems | Open Source

Building scalable backend systems, distributed microservices, and Digital Public Infrastructure that power millions of users.


👨‍💻 About Me

I'm a Technical Lead at Tunerlabs with 5+ years of experience building scalable backend systems using Node.js, distributed architectures, and cloud technologies.

My journey started as a Software Engineering Intern and has grown through Junior Engineer and Senior Engineer to Technical Lead, where I now lead engineering teams, architect backend services, mentor developers, and drive technical decisions for production systems used by governments and NGOs.

I enjoy solving challenging backend problems, designing scalable architectures, optimizing performance, and building software that creates meaningful impact.
