I build products that hold up in production.

8+ years of backend-heavy full-stack engineering for international enterprises and startups. I own the hard parts: authorization, data integrity, scale, and failure handling. I build with LLMs where they earn their place.

Products

Daily Investor ↗

Solo build · live

A watchlist-first news and research hub for Vietnamese retail investors. A crawling pipeline ingests VN finance news and broker reports, an LLM step summarizes and tags them, and the backend serves a daily digest, ticker and sector pages and a research assistant on the web and as a Chrome new-tab extension.

iBizConnect

Technical cofounder · 2025

A multi-tenant B2B platform for Vietnamese industry associations to run trade exhibitions and help member SMEs find partners, book meetings and record outcomes. I owned the architecture, with tenant isolation enforced at the auth layer, and took it from zero to production in ~7 months with a team of 4.
