I build things — systems, tools, products that live on the internet.

Sometimes they work exactly as intended. Sometimes they break in unexpected ways.
Either way, something gets learned, and I keep going.

I work as a Tech Lead by day. That means architecture decisions, code reviews, unblocking teammates, and constantly navigating the trade-off between shipping fast and not creating a mess. There's no perfect answer — only better decisions given the context.

• 🔨 Building small, useful products quickly
• 🏗️ Designing systems that are simple but scalable
• 🤖 Applying AI in practical ways — not just as a trend
• 🌱 Creating things that can grow organically through real user behavior

Lightweight products. Things that don't need heavy infrastructure or 6-month dev cycles.
Fast feedback loops. Real usage. Honest outcomes.

• 🌐 duynk.dev — personal blog & notes on engineering, products, and mistakes
• 🚀 runphp.dev — a product I'm currently building

No fluff. Just real work, real outcomes.
If something here is useful — that's enough.
