I'm a Senior Full-stack Engineer with 5+ years of experience building end-to-end products across web, mobile (iOS/Android) and backend, with a strong focus on AI/LLM systems. I currently build production LLM agents at VinGroup, and before that I co-founded an AI & mobile studio where I served as Tech Lead and board member, building the engineering team and owning architecture and delivery across all products. Two things I'm proud of: 1. At VinGroup, I built two LLM agents for a real-estate platform – a customer-facing assistant serving 200K+ monthly users and an internal sales assistant used by 200+ staff – plus a gateway proxy integrating multiple internal APIs and agents (Python, FastAPI, Next.js, Docker). 2. As Tech Lead, I architected a full-stack ad-management platform and a real-time landing-page engine serving 2M+ users at under 200ms latency across 2,000+ dynamic pages, along with an AI policy-detection system monitoring 20,000+ creatives with zero violations (NestJS, Next.js, AWS, Redis). My core stack is TypeScript, Python, React/Next.js, NestJS, FastAPI, PostgreSQL and AWS, plus LLM agent design, function calling and evaluation pipelines. Next, I'm looking for a remote senior or lead full-stack / AI engineer role at a product company, where I can own features end-to-end – from architecture to shipping AI-powered products to real users. I communicate in professional English and am comfortable working async across time zones.
