What I'm looking for

I’m open to fully remote roles or relocation to the UAE.

At Quecko, I lead engineering for Rain, a prediction market with 38K+ users and $60M+ in trading volume. I built its real-time trade engine and two-layer AI oracle, which gathers evidence and resolves or adjudicates market outcomes.

I’ve also delivered backend systems for fintech, trading, and blockchain products, including Rain’s settlement stablecoin and Resolution Center. My work spans Node.js and TypeScript, Python and FastAPI, and AWS infrastructure; I’m a Toptal Verified Expert in Engineering and have spoken on AI in Web3 and prediction markets.
