Job Success
Da Nang, Vietnam - 2:35 am local time
I build fast, scalable web applications — and I bring them to the next level by integrating the latest AI capabilities that actually move the needle for your business.
I build production-ready Agentic AI systems, RAG chatbots, and full-stack LLM applications that help businesses automate workflows, search internal knowledge, and turn complex data into intelligent AI assistants.
With hands-on experience across the full stack, I specialize in:
✅ AI & LLM Integration: OpenAI API, LangChain, LlamaIndex, Hugging Face Transformers, Vector Databases (Pinecone, Weaviate, FAISS), Embeddings, RAG, Prompt Engineering
RAG Pipelines: End-to-end Retrieval-Augmented Generation systems: document ingestion, chunking strategies, vector embeddings, and intelligent retrieval using tools like LangChain, LlamaIndex, Pinecone, and pgvector
✅ Frontend: React, Next.js, Vue.js, TypeScript, Tailwind CSS, Redux Toolkit, Zustand, React Query, Axios, Vite, Jest, Webpack, Jest, Cypress, PWA, SEO, Material UI (MUI), Ant Design, Chakra UI, ShadCN UI, Bootstrap, Tailwind UI, Mantine, Semantic UI
✅ Backend: RESTful & GraphQL APIs with Typescript / Node.js / Nestjs / Golang, built for scale and maintainability
✅ Database: PostgreSQL, MySQL, MongoDB, Redis, SQLite, Elasticsearch, DynamoDB, Prisma, TypeORM
✅ Mobile Apps: React Native, Flutter, Swift, Kotlin, Expo, Firebase, REST APIs, GraphQL, Redux, Zustand
✅ Desktop Apps: Electron, Tauri, NW.js, Qt, .NET (WPF/WinForms), JavaFX, PyQt, SQLite
✅ DevOps & Deployment: CI/CD pipelines, Docker, Nginx, cloud platforms (AWS / GCP / VPS), Kubernetes, Microservices — I don't just build it, I ship it live
Why work with me?
✅ I don't just write code — I understand the why behind your product and architect solutions that scale
✅ Clear, proactive communication throughout every project
✅ Deliverables that are clean, documented, and ready for your team to maintain
Whether you need a polished web app, a mobile app, a desktop tool, a smart AI-powered feature, or a full RAG knowledge base — I can take it from idea to live deployment, end to end.
