Hi, I'm Fathin 👋

indie founder and software engineer in my 20s. I build web and mobile products with AI at the core. shipping fast, learning in public, chasing freedom through products. very active on X.

About

I come from an engineering background, but I learned more by building real products than from any classroom.

In mid 2025, I quit my full time job to focus fully on freelancing and building my own products. Since then, I’ve been working on client projects while scaling SaaS products under Nightcoders.

I care about:

  • building fast
  • keeping things simple
  • shipping software people actually use
  • no hype. no fake growth. just real work.

Founder
I run a small tech studio focused on building modern web and mobile applications with strong AI integration. I build full stack products using Next.js, React Native, TypeScript, and Python, and design and ship AI features such as RAG systems, LLM workflows, and automation. I also run and scale internal SaaS products from zero to paying users, handling product, UI, backend, infrastructure, and deployment end to end.

Led the development of an internal AI chatbot used directly by real users. Built a Retrieval Augmented Generation chatbot connected to internal APIs and WATI, handled prompt design, vector search, and conversation logic, and implemented the system end to end, including backend logic and chat UX.
