Building tools that make professionals more productive.

Tung Pham · Software Engineer

9 years in mobile, shipping Flutter apps to 50,000+ users. Lately I've been learning to build end to end, from product and backend to AI, and I'm starting my own venture: AI for accounting, to help people get more done with less manual work.

What I'm building

Founder · Aug 2026 - Present

Accountant Agent

  • Started from a first-hand problem: watching my wife, an accountant, spend hours on manual computer work such as combing through Excel sheets and checking paper documents. That made me see how much of it AI could make easier and faster.
  • Exploring how far AI can go in accounting. A lot of the work is repetitive, and keeping up with changing regulations is hard for anyone. I want to build AI that can take on more of it, one step at a time.
  • Building an AI assistant for Vietnamese accountants that helps with routine bookkeeping, grounded in Vietnamese accounting law.
  • Building AI harness orchestration for accounting, working to turn general-purpose AI into something accountants can rely on.
