Projects
Identity, verification, credential wallets, weather and maps, and family products — built for real users at campus and consumer scale.
Campus identity, credentials, and notifications in one app.
The primary mobile companion for IIT Kanpur’s digital identity ecosystem. Students and employees access blockchain-backed digital IDs, dependent credentials, degree-related documents, event passes, and campus notifications — with cryptographically verifiable signed QR for on-campus use. Actively used by IITK users at 10k+ on normal days and peaking at 30k+ during campus events.
Verify credentials and gate access in seconds.
Companion verifier app used at campus gates and checkpoints. Staff authenticate IITK App holders via online/offline QR verification and BLE scanner devices — so the same active campus users get checked in quickly without oversharing sensitive details. Built for high-throughput verification where speed and trust matter most.
Verified degrees you can download and prove — fully offline.
Blockchain-secured credential wallet for graduates to access fraud-proof digital degrees and certificates, with DigiLocker credentials available for download and full offline use. Powers degree/certificate issuance for IIT Kanpur (up to ~3,500 students/year), IIT Jodhpur (~2,000), IIIT Lucknow (~2,500), and other institutes connected through C3iHub — plus SSL pinning, encryption, and secure local storage.
Cross-platform weather app with MapLibre, MET Norway, and Skia atmospheres.
Weather and location app for inspecting a place, seeing how conditions change, and deciding what to do. Current location, search, saved favorites, and map taps all feed one reading with hourly and daily forecasts. Privacy-first one-shot location, Skia weather atmospheres, deterministic rule-based insights, and a hexagonal architecture that keeps MET Norway and Nominatim behind clear boundaries.
Stories and songs that keep families close.
Family bonding app for parents, grandparents, and caregivers — especially across distance. Create and share interactive stories and nostalgic sing-alongs so kids recognize loved ones through familiar voices and content, not just random screens. Warm, kid-safe UX focused on connection.
