Overview

Full-stack engineer who built secure, scalable crypto systems and now ships AI/ML products using React/TypeScript, Rust, and Python.

Highlights

• Authored Bitcore – the first complete JavaScript Bitcoin library (4.9k stars, 2.1k forks, 500+ dependents).
• Scaled EarthBucks Rust/TypeScript stack to 1 k QPS on PlanetScale (8-node cluster).
• Co-invented two blockchain patents – Paymail (2019) & Token Re-issuance (2020).
• Integrated xAI & OpenAI APIs to power Hallucipedia (AI encyclopedia) and Chatvim (Neovim LLM plugin).

Exceptional Work (100 words)

In 2014 I single-handedly wrote Bitcore, the first complete Bitcoin SDK for JavaScript. I reverse-engineered Bitcoin’s C++ reference node, re-implemented its cryptographic primitives (incl. ECDSA) in pure JavaScript, and wrapped them in an intuitive, unit-tested API that ran in both Node and the browser. Bitcore shipped to production at BitPay within eight weeks, enabled their first web wallet, and quickly became the de-facto standard: 4.9k GitHub stars, 2.1k forks, 500+ dependent repos, and billions of dollars in on-chain value secured. The project demanded deep protocol knowledge, performance tuning, rigorous security review, and developer-experience obsession—skills I now apply to AI products.

Relevant Experience

• Shipped containers with zero-downtime rolling deploys (AWS ECS, fly.io).
• Implemented cryptography: ECDSA, CBC, HMAC, BLAKE3 in Rust/TypeScript/JavaScript/WGSL.
• Built custom ML tools – GPU-accelerated tensors in Rust/Nushell (Nutorch & Termplot).
• Processed $100 M + in peer-to-peer crypto transactions with no security incidents.
• Designed first WebGPU miner (BLAKE3 + matmul in WGSL).
