Andry Huang · Senior Full-Stack & AI Engineer
7+ years of enterprise SaaS, ERPs and LLM systems. Built from Surabaya, shipped for teams in Singapore.
I build the systems a business runs on: 3+ years of enterprise SaaS for Anacle Systems Ltd in Singapore, ERPs for shops that count gold by the gram, and Qualiv, the AI recruitment platform I founded. Mostly .NET Core, Next.js and NestJS, with RAG and LLM features in production.
