Nguyen Ho Lan

Full-Stack Senior Developer — 20+ years shipping production software, now building with AI-assisted workflows.

01

Profile

Senior full-stack developer with more than twenty years shipping production software across e-commerce, healthcare directories, booking platforms and large-scale data pipelines. At home in Python, PHP, .NET, modern JavaScript and both SQL and NoSQL databases. Today I pair that engineering experience with AI-assisted development — LLM agents, code generation, prompt engineering — to take an idea to a deployed product in a fraction of the usual time. Open to senior remote roles, contract engagements and freelance builds.
