AI applications · API platforms · Backend development
I build practical products that connect AI models, reliable data, and clear user experiences.
My work sits between AI integration, backend systems, and product development. I enjoy turning an idea into something people can open, use, and inspect — with working APIs, a usable interface, and documentation that matches the implementation.
My two featured projects are SHOP AI PRO, an AI service platform, and Library AI, a Vietnamese library assistant with source-grounded answers.
Using AI agents at the lowest possible cost while achieving maximum work efficiency.
That's what my job is really about.
AI services & API access platform

Vietnamese library assistant
Find books, check stock, and ask about library information. Answers link back to retrieved sources, with direct lookup when AI is unavailable.
|
| SHOP AI PRO | Library AI | |
|---|---|---|
| Product focus | AI service access and account resources | Library questions and book discovery |
| Backend work | Domain services, key access, credit and usage | Chat API, retrieval and catalog administration |
| AI integration | Model gateway and provider routing | nemotron-super with retrieved library context |
| Public access | Website, docs and an overview repository | Live demo and application repository |
| Scope | Overview is public; source code is private | Demo uses sample data and keyword retrieval |
The library assistant supports optional vector embeddings in the code; its current demo uses keyword retrieval, with citations and an explicit fallback. Its inventory and opening hours are illustrative, not official library records.
| Area | What I work on |
|---|---|
| AI integration | Model APIs, gateway integration, retrieval and grounded responses |
| Backend & data | API design, authentication, validation, credit/usage and relational data |
| Product interfaces | Storefronts, dashboards, chat interfaces and responsive layouts |
| Delivery | Containerized services, serverless deployments, testing and documentation |
Understand the user → connect the data → build the flow → test the behavior → deploy → document.
I use AI tools to support development while keeping implementation details, limitations, and verification results clear. I care about products that work beyond a screenshot.
