# Himanshu Maurya

> Full-stack engineer · creator of urls.bid · ex-CTO at SlaabAI. Based in India, working remote-first. Open to work — full-time, contract, or freelance.

I build and ship products end to end: real-time voice AI, AI-native tooling, crypto payments, macOS apps and developer CLIs. I took SlaabAI's real-time voice-AI platform from an empty repo to production as CTO, and I now build oss.codes and urls.bid.

## Writing
- [bunkill: making node_modules cleanup 2× faster on Bun](https://codingstark.com/blog/shipping-bunkill/): npkill crawls on a machine full of projects. bunkill re-does it on Bun with parallel scanning, a fuzzy picker and sort-by-size. The speedup came from refusing to walk the same tree twice.

- [urls.bid: three frontend migrations in a week (and why)](https://codingstark.com/blog/urls-bid-three-migrations/): urls.bid went Next.js → Astro 6 → TanStack Start in under two weeks. Each move solved a specific problem; here's the honest reasoning and what x402 has to do with it.
- [Qwen2.5-VL video captioning, native on Apple Silicon with MLX](https://codingstark.com/blog/qwen-vl-apple-silicon/): Replicating the Marlin-2B temporal-captioning paradigm on a Mac using MLX: sub-second visual grounding, entirely inside unified memory, no CUDA and no upload.
