Business context.
Engineering depth.

I’m Rangga, a fullstack engineer based in Bandung, Indonesia, with 9+ years of experience across real estate, beauty and consumer platforms, commerce, and financial services.

I’ve built contact management tools for real estate agents, backend services for consumer products, payment infrastructure, and internal business platforms. My work spans web and mobile applications, APIs, and the integrations that connect them.

Whatever the sector, I focus on understanding the workflow, making sound technical choices, and building software that is useful, maintainable, and practical to run.

What I’m exploring. AI-assisted applications, retrieval-augmented generation (RAG), and recommendation systems.
