Ivan David
AI Engineer / Full-Stack Developer / Designer
AI engineer, full-stack developer, and lately a brand designer. Been building on the internet for 6+ years. I started in crypto forensics, tracing funds for a law firm and investigating wallets at Metaplanet, then ran operations at an app studio for two years.
In 2025 I led AI product work on Metorial's serverless MCP runtime: fine-tuning LLMs, building RAG for agent integrations, shipping tooling with sub-second cold starts. This year I designed the brand for Death by Tea, and on the side I ship my own products: Clawbibi, Humanaid and Arabic-first OpenClaw agents for clients across the Gulf.
Right now I'm Lead AI Engineer at LinkCal, building the AI behind booking links, call recaps and crypto incentives. Welcome to my corner of the internet.
