Varun

i'm varun, a backend engineer from india.

i build backend systems, infrastructure, and distributed products.

i built CDeX, a distributed competitive programming platform for programming contests, code judging, realtime leaderboards, proctoring, and ai-assisted problem authoring.

i built tiny, a distributed url shortener built with go, clickhouse, redis streams, snowflake ids, distributed tracing, realtime analytics, and a terminal client.

i've also contributed to open source, including docker cli, docker moby, and pgrwl.

these days i'm mostly working with go, typescript, postgres, kubernetes, redis, and distributed systems.

i write here about things i build, things i learn, and the occasional deep dive into systems and infrastructure.

want to get in touch? i'm usually available on x, or you can reach me via email at varunhotani@icloud.com.
