I design and ship production SaaS, evidence-backed AI agents, and on-chain systems with verifiable decisions, payments, and outcomes.
01 / Publications
Research, published.
Peer-reviewed work spanning edge computing and cryptocurrency analytics.
02 / AI Agents & Web3
Agents that pay their own way.
My 2026 focus: evidence-backed agents + x402 agentic payments + verifiable on-chain outcomes. Ten-plus hackathons and ecosystems across Arc, Base, BNB, Casper, Creditcoin, Somnia, and Starknet.

★ 3Agora Agents Hackathon · Canteen × Circle × Arc
Standouts winner. An AI oracle paid over x402 for prediction markets, where every price ships with a Merkle-rooted reasoning DAG (byte-verifiable, SHA-256 per node), settled on Arc in <1s (~$0.0007/receipt). Ensemble of 5 agents: Bull/Bear/Edge (parallel Gemini, isolated context) feed a Supervisor (weighted-Bayesian + Brier priors), then a Critic. 4,558 on-chain receipts · 217 markets · cross-chain CCTP V2.

06 / About
A generalist who ships.
I'm a full-stack engineer with 4+ years building and shipping production software end-to-end: SaaS platforms, developer tools, and, most recently, autonomous AI agents. I learn fast, work independently, and care about the whole path: from the first line of code to a system that stays up in production.
Author of ContribAI (244★, 686 tests, Rust/Tokio) and creator of Keryx, 1st-place winner at the Lepton Agents Hackathon 2026. Across GitHub: 112 public repositories and 97 reviewed pull requests merged into upstream projects.
Product & Full-Stack
From API design and Node.js/Python/Rust backends to React & Astro frontends. I take SaaS products from zero to production, then keep them running.

AI Agents & Web3
Evidence-backed agents with explicit policy, portable receipts, and verifiable on-chain payments. That thread runs through ContribAI, Keryx, AgentTrial, and my 2026 hackathon work.
