I'm a full-stack developer from Ho Chi Minh City, Vietnam, who started in the PHP trenches and now thrives across the entire stack — especially where AI meets scalable infrastructure.
Currently passionate about:
- Building real-time, privacy-first AI tools
- Fine-tuning LLMs (OpenAI, Gemini) for specialized tasks like translation & agents
- Creating lightweight, high-performance alternatives to bloated solutions
- DevOps & cloud automation (AWS Lambda + SAM, servers that just work)
I believe in simple, clever systems that solve real problems without unnecessary complexity.
Here are some of the things I'm most proud of right now:
| term2 A terminal-based AI assistant, think of Claude Code and Warp getting married and having a child TypeScript |
chat Lightweight AI chat frontend — because OpenWebUI feels too heavy TypeScript |
ocr Privacy-first, fully browser-based OCR — no data leaves your device TypeScript |
| code-rag Semantic code search MCP server for smarter coding agents Python |
claude-skills My growing collection of Claude skills & tools Claude Skills |

I also build lightweight, practical web tools that solve everyday developer pain points — all 100% client-side, no backend needed.
