I’m Duc Nguyen, a full-stack developer from Ho Chi Minh City, Vietnam. I started in the PHP trenches and gradually expanded across the stack, building products that blend practical UX with reliable infrastructure. Today, I focus on privacy-first AI tooling, scalable backend systems, and lightweight developer utilities that remove friction.

What I’m working on

• Real-time AI tools: terminal assistants and chat frontends that stay fast and safe.
• LLM workflows: fine-tuning OpenAI & Gemini models for specialized translation and agent tasks.
• Privacy-first apps: browser-only OCR and offline-ready utilities.
• DevOps automation: AWS Lambda + SAM deployments and reliable release pipelines.

Core strengths

• Frontend: React, Vue, TypeScript
• Backend: Node.js, PHP, Python, SQLite
• Infrastructure: AWS, Docker, Linux, CI/CD
• Tools: Git, Vim, CLI automation

I believe in simple, clever systems that solve real problems without unnecessary complexity. If you’re looking for someone who can ship AI products end-to-end—while keeping performance and privacy front and center—let’s connect.
