Numbered docs, API contracts and a phase plan
APIs, web panels and mobile apps on one backend
Path-filtered CI: lint, unit and e2e on real Postgres
Multi-stage images, one tag per commit
Private network, SSH, migrate, Compose up
Health checks and endpoint probes; auto-rollback on failure
Nightly backups, restore drills and runbooks
One platform for clinics, hospitals and their patients. It covers appointments, e-prescriptions, wards, beds, billing, staff attendance, payroll and stock, and patients get an offline-first app in English, Hindi and Gujarati.
A digital product passport that began with EV batteries under the EU Battery Regulation and now covers any product with a lifecycle. Each product is recorded on-chain and gets a public passport with a QR code that anyone can verify.
An event platform where organisers list events and control every rule: guest lists, ticket splitting, group passes and entry limits. Attendees get signed QR tickets that verifiers scan at the gate in under a second, even offline.
Institute management for coaching classes and schools, with a public course marketplace beside it. It handles geofenced staff check-in, clash-free timetables, attendance, fees and payroll, plus recorded lectures and live classes.
