Project 02 / 04

atamatax

file your taxes without an accountant

A guided, question-by-question tax engine that turns the annual return into a 20-minute conversation. No spreadsheet, no accountant, no jargon — answer plain questions, atamatax computes and fills the rest.

What shipped

  • Built the tax-logic calculation engine from scratch — every rule, no library
  • Solo across the stack: product, UX, frontend, backend, tax engine
  • Turned an accountant-only domain into a 20-minute self-serve flow
