Siddheya Kulkarni

software engineer / pune, india

I write code that gets merged.

I build developer tools and ship to open source projects that thousands of engineers depend on. Lately that means workflow orchestration at Kestra, AI agents at DocsGPT, a SQL workspace at Tabularis and electronics-as-code at tscircuit.

By day I'm a software engineer at Capgemini. By night I'm usually reading someone else's codebase.

Building

Where did 200 GB go on my dev machine?

A disk cleaner for developers. Finds the space your tooling quietly eats and removes it with per-ecosystem rules that know what's safe.
