Experience

Flutter Developer · Sublimity Softwares Private Limited

Feb 2023 – Present

Delivered 6+ production Flutter applications on Android and iOS for international clients across five domains — fire-safety inspection, HR and workforce management, food delivery, real estate and community platforms — using Clean Architecture with BLoC and GetX.

FireArrest: Rebuilt the app from scratch and migrated operatives from two legacy native apps (Android and iOS) with zero data loss, using conflict-aware background sync (WorkManager, BackgroundFetch), Drift/SQLite and Dio-based REST APIs.
Shipped four types of pin-level inspection evidence — photos, QR codes, dynamic forms and digital signatures — so inspectors complete full reports without connectivity.
ClockedIn HRM / Zaad HR: Shipped two branded flavours from one Flutter codebase, gating 50+ screens across 30+ feature modules with OAuth2, MFA and role-based entitlements (GetX, Dio).
Implemented three clock-in methods — face recognition, NFC and PIN — with GPS validation using ML Kit and TFLite, backed by an ObjectBox offline punch queue and background sync, plus roster, leave/WFH, timesheet, payslip and document-upload workflows (MinIO/S3).
Attendance kiosks: Designed and built facial and palm-biometric attendance kiosks from scratch, with native kiosk lock-down, boot auto-start, NFC fob and PIN authentication, IMEI-based device provisioning and S3 biometric template sync.
WeWeed: Wrapped a production PWA in a native Flutter shell with OTP/2FA authentication, session bridging (token refresh, remember-me, cookie injection), Stripe and PayPal payments, and FCM push notifications with deep links.
PosWave: Built the customer-facing ordering flows — menu browsing, cart and order placement — with REST API integration and account authentication.
1 Reception & PropertyApp: Integrated Razorpay payments and advanced search and filtering, and migrated state management from Provider to GetX while keeping production stable.
Localised applications into English, Hindi and Arabic (RTL), and added Firebase Crashlytics, Remote Config and DEV/PROD build flavours.
