Raymart "Imat" Marasigan

AI Software Engineer

I build LLM applications and multi-agent systems in Python and TypeScript. Before AI, I spent 11+ years in software, most of them co-running Dthree Digital, shipping 100+ production websites and platforms with Next.js, NestJS, React and Node.js, so I know what it takes to get from prototype to production.
