AI engineer and founder of NYX, a one-person software studio. I ship production AI products end to end, with a deterministic core and the LLM kept at the edge — five products live in 2026, 2,000+ passing tests across them. BSc, University of Waterloo.

Experience

Founder & Engineer — NYX Studio · Vietnam

2026 – Present

Built and run chessova.com, a live chess platform with tournament broadcast, dual-engine analysis, a 25,000-puzzle bank, a Remotion-based clip studio, and a paid Pro tier; 1,400+ passing tests.
Built Guardian, a compliance console that blocks non-compliant product listings against real law with a deterministic verdict engine — Runner-Up, Retail track, Agentic AI Build Week 2026 by GenAI Fund; swept 48 live product pages with zero false positives.
Built Wingman, a chat-commerce agent for the KFC Vietnam menu with deterministic, server-side pricing on every order; 65 tests.
Built Nyx Persona, a human-gated AI social publisher — approvals are cryptographically bound to the exact published bytes via sha256; 480 tests.
Took over a teammate's hackathon build and re-architected it into Randy, a bilingual retail sales agent over an 11,865-SKU catalog — search, comparison and PC builds decided by server code, hardened across six adversarial stress rounds; tests 44 → 327.
Delivered a bilingual corporate site for V.Star, a Vietnamese industrial group (327-web.vercel.app).
