I build systems,
with controlled AI.

I'm Nguyễn Khanh Huy, a software engineer based in Ho Chi Minh City, Vietnam. I own APIs, UI, database architecture, and deployment — applying AI with strict controls (retrieval, verification, ops) rather than unchecked prompts.

Graduation Capstone Thesis — DUT (2026)

Graduation Capstone Thesis at DUT: Tamper-proof diploma verification on Ethereum Sepolia testnet combined with a local RAG assistant.

  • ↳End-to-end diploma issue, verify, and revoke workflows (admin management + zero-barrier public verification)
  • ↳SHA-256 document hashes stored on Sepolia as compact bytes32; decoupled React, Node.js/Express, MongoDB, and FastAPI services
  • ↳Local RAG pipeline (FAISS + Qwen 2.5 via Ollama) over institutional docs for grounded answers with page citations

Shipped web application (since taken offline) featuring streaming Server-Sent Events, constrained Gemini API integration, and DigitalOcean production deployment.

  • ↳Shipped full product to production on DigitalOcean and operated live with real user traffic
  • ↳Owned production basics: multi-stage Docker containerization, Nginx reverse proxy, Cloudflare SSL, and env/secrets isolation
  • ↳Treated LLM as a constrained system component: real-time SSE streaming, structured prompt boundaries, and output truncation handling

What I Build

Engineering capabilities centered around building reliable software, backend systems, and controlled AI.

01

Full-stack Applications

Web applications built with React, Next.js, and Node.js, delivering responsive interfaces, end-to-end data integrity, and clean database workflows.

Next.jsReactTypeScriptTailwind CSS
02

Backend & Systems

Type-safe REST APIs in Node.js/Express and Python/FastAPI, structured MongoDB schemas, authentication, and clean service separation.

03 / ABOUT

Passionate about building software that delivers value.

I'm Nguyễn Khanh Huy, a software engineer based in Ho Chi Minh City, Vietnam. I own APIs, UI, database schemas, and production deployments — engineering reliable web systems with controlled AI integrations.

My focus centers on modern full-stack systems, backend services, and verified AI pipelines. Recent work includes D-CERT (Separated Web3 & AI RAG architecture for diploma verification) and Tarotica (shipped production web app with Gemini API and DigitalOcean ops, now offline).
