- Built what users asked for. Grew it from a surgical-decision simulator to a paid launch in two months by adding topic guides, drug references, and past papers. Approximately 100 daily users as of September 2026.
- Content pipeline. Turns 350+ topic PDFs co-written by clinicians into live lessons through staged, fail-closed steps: deterministic extraction, reviewer-confirmed structure, and one small model task per block. AI then checks each claim against sources before a clinician approves it, on a self-hosted job queue that survives dropped connections.
- Self-healing billing. Webhooks, an on-demand check, and a 30-minute reconciliation job share one idempotent apply step, so missed or duplicate Razorpay events recover automatically. Upgrades confirm the new UPI mandate before cancelling the old one, preventing double charges.
- Offline-first sync. Cut database writes by 80% (about 50K → 10K rows a day) with a batched outbox that works offline, deduplicates resent operations, and stops stale devices from undoing newer changes.
- Growth. Creator referrals with payouts, a library of 500+ images from 40+ clinicians, a pricing page rebuilt around free samples after user feedback, and a 9K+ Instagram audience (@pan.oph).
