Muhammed Jafseel M • Senior Flutter Developer • Kannur, Kerala, India
I provide software agencies, product companies, and founders with dedicated Flutter subcontracting, fast bug fixing, API & Firebase integrations, and reliable cross-platform app delivery. Backed by 8+ years of mobile engineering (4+ in Flutter) and deep native Android roots.
No arbitrary percentage bars or vanity metrics. Every technology below is backed by real production deliverables across Android, iOS, and macOS applications.
When cross-platform abstractions hit native OS limits—such as background execution, push notification delivery edge cases, Gradle build toolchains, or native camera bridging—my 4+ years of native Kotlin and Java engineering (within 8+ years of total mobile engineering) ensure problems get resolved at the platform level instead of stalled.
Strong typing, asynchronous programming, and cross-platform native logic.

Push notifications, error telemetry & crash triage
Agile sprint workflows, branch strategies, code reviews
I adapt to your team's existing architecture rather than forcing dogmatic rewrites. Here is how I apply state management in production:
Selected for Meerkat AI Chat & Joinery. Excellent for compile-time safety, auto-dispose, and reactive stream pipelines with Drift SQLite.
Applied in CoreSyn Fitness & Smart Saver. Ideal for strict enterprise predictability, multi-step calculation wizards, and auditability.
Used in Byvrio Member App. Streamlines routing, reactive bindings, and lightweight dependency injection for agile team velocity.
Employed in Autoclinch. Lightweight, straightforward, and zero-overhead for location tracking and fast utility workflows.
In-depth architectural breakdowns of real applications I engineered or led. Every case study documents actual state management solutions and real technical challenges.
Cross-platform real-time chat application with low-latency messaging, offline SQLite caching, and multi-platform deployment across Android, iOS, and macOS.
Healthcare-focused mobile application for medication tracking, pharmacy discovery, family member management, and insurance data handling.
High-trust professional dating application featuring automated government ID verification, age validation, and secure onboarding.
Small, well-defined tasks are fastest to approve and deliver immediate value. Lead with one of three focused engagements, or partner on ongoing agency subcontracting.
Rapid diagnosis and surgical fixes for elusive UI glitches, state desync, platform crashes (ANRs/iOS), and store release-blocking build errors.
Connect your Flutter app to backend REST APIs, Firebase cloud services (Auth, Firestore, FCM), or implement new production-ready UI screens and workflows.
Plug an 8+ year mobile engineering veteran (4+ years Flutter, 4+ years Native Android) into your agency's client projects with zero hand-holding and transparent communication.
In addition to focused sprints, I take on full mobile app development (turnkey MVP to store launch) and legacy architecture modernization on structured milestones.
A predictable, transparent engineering process designed to eliminate surprises, keep stakeholders informed, and deliver maintainable code.
Review your feature specs, Figma designs, bug logs, or product goals to clarify exact acceptance criteria.
Inspect your existing Flutter codebase, state management, and dependencies to define exact technical scope.
Agree on milestones, deliverables, test requirements, cost, and delivery schedule before writing code.
Build features with clean architecture and SOLID principles, accompanied by clear asynchronous updates.
Validate on physical Android and iOS devices across screen sizes, offline transitions, and edge cases.
Deliver clean git pull requests with full documentation, architectural notes, and verification guides.
Support release submissions to Google Play & App Store, with follow-up warranty for delivered milestones.
Transparent written communication, manageable milestones, and proactive escalation of blockers.
I am a mobile application engineer based in Kerala, India, with 8+ years of total mobile engineering experience, including over 4 years building production Flutter applications.
Most recently, I served as a Senior Flutter Developer at Cloudium Software (Mar 2022 – Sep 2025), where I led cross-platform Flutter development across Android, iOS, macOS, and Web, mentored engineering teams, and managed production releases on Google Play Store and Apple App Store.
Prior to specializing in Flutter, I spent over four years engineering high-scale native Android applications using Kotlin, Java, MVVM, and Room SQLite. This native grounding allows me to troubleshoot low-level OS issues, performance bottlenecks, and build toolchain errors that trip up purely cross-platform developers.
