What I'm looking for

I seek remote or hybrid roles where I can lead fullstack development, modernize legacy systems, build multi-tenant SaaS, and implement production-ready RAG AI solutions.

I am a senior fullstack developer with 22+ years of software experience and 15 years working remotely, focused on building multi-tenant platforms, Indonesian business systems, and legacy modernization.

I have delivered 50+ production systems across finance, e-commerce, and SME sectors, led invoicing/tax compliance projects, implemented RBAC and workflow engines, and reduced approval cycles through automation.

I design and implement production-ready RAG AI systems (LangChain, Gemini, Qdrant), modernize monolithic PHP apps to API + React frontends, and manage full project lifecycles with strong remote collaboration practices.
