Hi, I'm Farook Jamal K
Senior Flutter Engineer building production mobile apps & SDKs.
5 years shipping cross-platform apps for enterprise logistics, identity, and consumer products. I work where Flutter meets native — Kotlin platform channels, hardware integrations, and offline-first architecture.

Capabilities
What I Bring
Flutter is my primary stack. Everything below is graded by how deep I actually go.
Flutter & Dart
5 years building production apps and SDKs. Two packages published on pub.dev. This is where I go deepest - offline-first architecture, custom render logic, and platform channel work.
Native Interop
Kotlin platform channels for hardware integration - barcode scanners, thermal printers over raw TCP, and native module bridging.
Offline-First Data
SQLite and Drift, transaction batching, background sync, schema migration.
App Security
Symbol obfuscation, SPKI certificate pinning, R8 rules, runtime protection.
CI/CD & Release
Fastlane pipelines, Dockerized GitLab runners, Firebase App Distribution, S3 artifact delivery.
State & Structure
Bloc, Cubit, Riverpod. Clean Architecture, MVVM, SOLID.
Firebase
Auth, Firestore, Cloud Functions, Remote Config, Crashlytics.
React Native
I ship in it when a project calls for it. Flutter is where my depth is.
React / Next.js
Production-capable on the web - this site is Next.js. Not my primary focus, but I build and maintain it end to end.
Selected Work
Featured Projects
A selection of mobile and web applications I've built, focusing on performance and user experience.
Enterprise / Logistics
WMS Mobile App
The WMS (Warehouse Management System) mobile application helps warehouse operators manage inbound, outbound, packing, shipping, internal and external transfers, cross-docking, and general scanning from a single Flutter-based client. Built for an enterprise logistics workflow, the app enforces a pallet-only receipt model and dynamically routes API requests to the correct warehouse environment at login. Its modular clean-architecture design separates core services, presentation, and environment configuration, allowing the same codebase to support multiple client workflows.

Superr | Digital Parenting
A comprehensive digital parenting ecosystem designed to keep children safe online, eliminate digital distractions, and foster healthy habits. Spearheaded development as Feature Head for the parent companion app at Coinductive Technologies, leading a 4-member Flutter team to architect real-time child device monitoring via WebSockets, Google Maps geofencing with live boundary triggers, a multi-tier permission onboarding pipeline, and customizable study/bedtime routines.

Exploring independent product engineering, AI automation, systems-level builds in Rust, and published packages.
zpl_kit (pub.dev Package)
- →A declarative layout engine for generating Zebra Programming Language (ZPL) strings with Flexbox-like components.
- →Provides coordinate-free design using ZplColumn, ZplRow, and ZplPadding to transform component trees into raw ZPL strings.
- →Includes widgets like ZplText and ZplBarcode, complete with comprehensive DartDoc coverage and published natively on pub.dev.
font_fit (pub.dev Package)
- →A drop-in replacement for Flutter's Text widget that automatically scales its font size down to fit within the available width/lines.
- →Uses a fast binary search algorithm to find the largest font size that still fits the box without overflowing.
- →Published on pub.dev, functioning natively across all Flutter platforms (Android, iOS, Web, Desktop).

Experience
Work History
My professional journey in software engineering and mobile development.
- Developed a high-performance Android WMS featuring native hardware integration via Kotlin Method Channels for Zebra's DataWedge barcode scanners. Architected complex logistics modules for location tracking and storage workflows, and implemented custom ZPL logic for thermal label printing across distributed warehouse environments. Engineered full RTL (Right-to-Left) support with Arabic i18n.
- Built a Flutter-based SSO SDK integrating new cross-platform applications into Manorama's 10M+ user identity ecosystem, supporting JWK verification and Google/Apple/Facebook logins. Redesigned user flows, managed external team handovers, and improved documentation.
- Stabilized multiple legacy Flutter apps (BuddyGuru, Epic Voucher, Hello Address, internal event tools) by resolving production crashes, upgrading outdated dependencies, modernizing build pipelines, and integrating SSO — improving reliability across apps with 100k+ downloads.
- Architected and built a modular, offline-first analytics SDK (Lens) entirely in Flutter/Dart, handling offline workflows, event capture, crash logging, batching, schema validation, local DB persistence, and background sync without third-party trackers.
- Led a 4-member team through design, development, and testing of a parental control app, now live on Google Play with strong user reviews.
- Engineered core features including geofencing, biometric authentication, deep linking, push notifications, and real-time updates with WebSockets.
- Established scalable Bloc/Cubit state management and integrated Flutter with native Kotlin modules, laying the foundation for maintainable long-term growth.
- Collaborated directly with product and management teams in a fast-changing early-stage environment, adapting to rapid feature expansions and technical pivots.
- Designed and shipped production-grade Flutter apps including Proofile.in (10K+ installs) and Doodhman — implementing full product flows like payments, wallets, subscriptions, maps, onboarding, and responsive UI across Android/iOS.
- Engineered Gomenu, a responsive restaurant menu system allowing users to scan on-table QR codes to place orders directly from their mobile devices.
- Led the full technical rebuild of Proofile.in, owning architecture, API design/integration, state management, and feature delivery end-to-end while working directly with founders, designers, and clients.
- Built a fitness-tech MVP during the pandemic — a complete gym management prototype with session scheduling, trainer allocation, fee collection, and exercise timers. Conducted on-ground validation with gym owners.
