BACKEND ENGINEER · AI BUILDER

Turning noise into signal.

I’m Sai — I build backends and AI-driven products that help people see what’s real. Currently shipping TruthLens, a real-time fact-checking overlay for your phone.

(01) — ABOUT

I design and build the systems behind products — APIs, data pipelines, and the AI glue that makes them feel intelligent.

My background is in web and backend engineering — Python and FastAPI are home base. Lately I’ve been pushing into mobile, teaching myself Android to bring my ideas all the way to the device.

I like problems where correctness matters: fact-checking, finance, anything where being right beats being flashy. The flash is just how I get people to look.

TruthLens

A real-time misinformation overlay for Instagram. A floating button captures what you’re viewing, reads the claim with on-device OCR and audio transcription, and checks it against the live web using Claude — returning a traffic-light verdict in a bottom sheet.

  • Privacy-first: only extracted text leaves the device, never your screen.
  • Claude tool-use for grounded, web-searched fact-checks.
  • App-agnostic architecture — Instagram first, extensible anywhere.
