Building fast, secure web products and using AI where it actually helps. No fluff, no hype.
I am a full stack developer and web security specialist with 14+ years of shipping real products, fixing real bugs at 3 AM included.
Stack I reach for: Node.js, Next.js, PHP, Python, MySQL, Redis, Docker. On the security side I focus on web hardening, OWASP audits and responsible pentesting.
Lately I build agentic AI tooling: data prep, small model fine-tuning, and production pipelines for clients. My philosophy is simple. Ship early, log everything, skip the over-engineering.
14+ years across the full stack. Here is where I go deep.
Technical notes drawn from real projects: frontend, backend, AI, security, SEO, mobile apps and media.
Available for full-stack builds, product engineering and security audits, from startup to enterprise.
iPhone and iPad app for credit cards, loans and pay-later wallets, built for card holders in Vietnam: shared limits counted once, due reminders, on-device import of PDF statements, SMS and screenshots, offer-aware card advice and an AI assistant that only drafts. No account, no server.
