Ayushi Gupta

I build products where mistakes are expensive.

Consumer credit, trading systems, government transactions. Four years across three industries where the model, the money and the regulator all have to agree.

I'm a product manager who builds - I write the decision logic, wire up the systems it depends on, and ship the screen the user sees.

AI agents for funnel forensics

When a funnel breaks, these agents read code, logs, events and user records in parallel and come back with the cause.

The analytics stack the firm runs on

Every dashboard, pipeline and KPI, built from nothing, then rewritten to cost $25 a day instead of $50K.

  • $50K/day → $25/day
  • Retention 45% → 67%

Three very different rooms.

A lending app, a trading floor, and a ministry. In all three, the cost of a wrong decision showed up in someone’s money.
