Workctrl — workplace operations platform

50K+users · 0.21% crash rate

Enterprise app (room booking, visitor management, food ordering). I own payments & security.

  • Payment-grade reliability: idempotency keys, exactly-once UPI across app-switch round-trips, hold-release watchdog.
  • VAPT hardening — SSL public-key pinning, device-integrity gate, hand-authored native jail-monkey patch.
  • OneSignal deep-routing (~20 types); Firebase RTDB live order tracking; Expo 53 / 16 KB migration.

Meeting Room Tablet — real-time room kiosk

80–90%fewer Firebase reads (measured)

A wall-mounted booking kiosk with on-device face-recognition check-in, live across meeting rooms.

  • On-device face recognition in native Kotlin + OpenCV (blink/texture/motion liveness) — no cloud round-trip.
  • Owned the transport migration Kafka → Firebase RTDB; bounded rolling-window query.
  • Fleet ops: heartbeat monitoring, UAT/PROD switch, quick-book / check-in / extend / end.

Mobile03 · SW Tickets

SW Tickets — internal support ticketing

Zero-releaseworkflow changes — server-driven

Lead author. A backend-driven workflow engine: the server defines valid transitions and fields; the client renders whatever it permits.

  • Role-gated UX from one codebase — manager (KPIs/all tickets) vs user (raise + mine).
  • Multi-step Raise-Ticket form with cascading fields + S3 presigned attachment upload.
  • Keycloak PKCE with single-flight refresh; Sentry + Clarity observability.

Smart Setup — IoT device onboarding

~40%fewer provisioning failures

Greenfield provisioning wizard for Sonoff/Tasmota Wi-Fi switches across 60+ smart-building campuses.

  • Concurrent mDNS + /24 subnet discovery (abort-on-found, DHCP-first).
  • Two-backend model (BMS ObjectIds vs Core GUIDs) with a translation layer.
  • NetInfo-aware flow suspends on Wi-Fi instability before bad state is written.

NoWorriesApp — mental-wellbeing tracker

~30%fewer redundant network calls

A guided worry-logging and mood-tracking app — recognise, manage, and ease a worry, then track how you feel over time.

  • Happiness Tracker across five life areas with a tracked happiness index over time.
  • Guided "My Journey" worry flow; response caching + request deduplication.
  • Shipped to both the App Store and Google Play, architecture through release.

Clinicards — EU patient-recovery platform

18hospital & clinic builds from one codebase

A home-monitoring app for post-op recovery: patients log health metrics along a carepath and watch their trends. Built across React web and React Native — my clearest proof of "two platforms."

  • 53 metric-card types (pain, mood, blood pressure, range-of-motion, recovery %) with Victory Native trend charts.
  • White-label for 18 org builds via 42 feature flags + per-tenant theming, all from one codebase.
  • AWS AppSync / GraphQL (Apollo) backend; Cognito auth with MFA + biometric/PIN; GDPR flows.
