building thoughtful systems.
Rasha Hantash
I work on the unglamorous systems early-stage startups depend on — the work that keeps both customers paying and teammates in flow-state.
Previously co-founded a legal-tech platform that serviced $1B+ in class-action settlements.
A note — in plain language
Most of my work has been zero-to-one: founding engineer at Zingage, data pipelines at Anterior, and co-founding Chariot Claims (formerly ClaimClam). What I’ve learned from those teams is harder to put on a resume.
The teams I’ve worked best with treat their processes as experiments and write things down for the engineer no one’s hired yet. They make space for two kinds of questions:
- what’s actually working in how we operate
- what problem are we trying to solve in the first place
Outside of tech I enjoy people-watching at Bar Valentina, art-gallery hopping, thrifting, and shazaming songs everywhere I go.
Writings
Working notes on Go infrastructure, RAG pipelines, AI agents, and the systems thinking behind reliable software.

Running Claude Code on a Hetzner VPS
How I run Claude Code on a Hetzner VPS over Tailscale: the components I use, the setup process, and an automated installer that compresses a 90-minute walkthrough into roughly ten.

Sandboxing Claude Code in Docker: From Naive to Hardened
How I evolved a containerized Claude Code setup from 'it works' to actually secure — Docker secrets, read-only mounts, scratch clones, non-root runtime, and what Anthropic's own reference does differently.
