# Himanshu Maurya

> Founding AI engineer at Krexa · creator of urls.bid · ex-CTO at SlaabAI. Based in India, working remote-first. Founding AI engineer at Krexa (since Aug 2026); open to select contract and advisory work.

I build and ship products end to end: real-time voice AI, AI-native tooling, crypto payments, macOS apps and developer CLIs. Since Aug 2026 I am a founding AI engineer at Krexa (krexa.xyz). I was CTO at SlaabAI, working on its real-time voice-AI platform, and earlier built urls.bid, a crypto-native link platform. I also run the oss.codes open-source org.
