Viet N.

I'm a Senior AI & Backend Engineer with 11+ years of experience, building software for startups and product teams. My main stack is Python/FastAPI, PostgreSQL, Redis, Docker, and AWS/Azure. Over the last few years, more of my work has moved into LLMs, RAG, AI agents, document processing, and workflow automation. ⚡ RECENT WORK → Real Estate AI — Built AI features for a platform used by real estate agencies in Australia and New Zealand, including property appraisal, reporting, document generation, and integrations with property data providers. → Insurance AI Triage — Built a system that reads incoming emails and documents, classifies requests, extracts structured information, and prepares responses for the team. → RAG & LLM Workflows — Built retrieval and LLM workflows for internal documents and business data. → Backend Systems — Built and maintained backend services with complex APIs, third-party integrations, background processing, and large amounts of data. ✓ WHAT I CAN HELP WITH • Python, FastAPI, Django, NestJS • OpenAI, Claude, Gemini • RAG, vector search, retrieval pipelines • AI agents and tool calling • Document processing and structured extraction • PostgreSQL, Redis, backend architecture • REST APIs and third-party integrations • Docker, AWS, Azure, CI/CD • React/Next.js when frontend work is needed → HOW I WORK I'm comfortable joining an existing codebase or building something from the beginning. I can work from product requirements without needing every technical detail specified upfront, and I'll raise questions early when I see something that may cause problems later. I try to keep the architecture practical. Sometimes a problem needs an AI agent; sometimes a normal API, background job, or automation is enough. If you're working on an AI product, SaaS platform, or backend system, feel free to send me the details.
