In build (Oct 2026)

  • Bill tracking & proof of delivery for an FMCG distributor: office imports the day's Tally bills, delivery staff capture proof on their phones (works offline, Hindi first).
  • QR visitor gate-pass app for a school: parents request a pass, staff approve, guards scan at the gate. Designed for low-end Android phones.
  • Law-firm websites in Dehradun and Nashville, USA.

Other client code stays private. I'm happy to walk you through any of these on a call.

Engineering you can read

  • PyDB — a transactional storage engine in pure Python: 8 KB pager, B-Tree indexes, write-ahead log, crash-recovery tests. Runs in the browser →
  • Distributed-Task-Scheduler — Redis-backed scheduler: delayed jobs, at-least-once delivery, worker crash recovery, live dashboard.
  • nexus-chat — real-time messaging with write-behind persistence, read receipts and 1:1 WebRTC video.
  • transit-pulse — live map of Delhi buses from the city's GTFS-Realtime feed.

Day to day I'm also the top contributor (711 of 1,100 commits) on a multi-tenant ERP, and I've built for a healthcare platform used by 2,300+ clinics.
