I build and fix Flutter apps for a living. Mostly the second one, if I'm honest. A lot of the work that lands on my desk isn't a blank slate. It's an app that's already live, already has users, and something's broken, slow, or held together with duct tape. I like that kind of work. Give me an existing codebase and I'll dig into it, figure out what's actually wrong, and fix it without creating three new problems in the process. Over the past 5+ years, I've shipped 10+ apps across fintech, health, e-commerce, and social, including eNaira (Nigeria's digital currency), BellBank, Track-A-Pitch, QuickChorse, DellCart, Xpress, Savetra, Airpero, Zonapop, Perozona, Delivrax, Bettalyfe, Towmi, Leasestash, etc I've worked on both new mobile applications and existing production apps. That includes building new features, fixing bugs, improving performance, integrating APIs, working with Firebase, and getting applications ready for release on iOS and Android. Some of these apps have reached 100K+ downloads, and I've had clients keep me around for ongoing development, maintenance, and support. One client relationship alone has grown into multiple engagements because they keep coming back when there's something important that needs to get done. Speaking of clients, here's what one recently said after we completed a major Flutter application redesign: "Working with Matthew is always a great experience. He was responsive, professional, and delivered high-quality work throughout the project. We completed a major redesign of my Flutter application, including a complex UI refresh, new analytics, and numerous bug fixes. Communication was excellent, deadlines were met, and the final product exceeded my expectations." Another client, after working with me on a complex feature, said: "As always Matthew delivers. I will continue to say it, he's the best Fullstack developer I've ever worked with! Our latest release would have taken my prior developer 5 days. Matthew turned this over in a day, with excellent code craftsmanship." My recent Upwork clients have also consistently endorsed me for being Reliable, Committed to Quality, Solution Oriented, a Clear Communicator, and Detail Oriented. I mention that because those aren't just words I chose for my profile. They're what clients have actually said about working with me. What I actually do: • Flutter and Dart mobile app development • iOS and Android app development • Cross-platform mobile application development • Building new features and improving existing applications • Mobile app bug fixing, debugging, and performance optimization • API and REST API integration • Firebase and Cloud Firestore • Authentication and user management • Payment and subscription integrations • Push notifications and real-time features • Mobile app testing and production readiness • App Store and Google Play release and deployment • Code refactoring, architecture improvements, and working with existing codebases On the backend and integration side, I also work with Node.js, Laravel, FastAPI, and other third-party services when the project needs someone who can understand more than just the mobile frontend. I'm comfortable stepping into an existing codebase, understanding how it works, finding the root of a problem, and making changes without treating the whole application like something that needs to be rebuilt from scratch. And if you're starting from zero, I can take the same approach in reverse. I'll understand the requirements, help make the right technical decisions, build the application, connect the APIs and services, test it properly, and get it ready for production. I don't just take tickets and write code. I ask questions when something doesn't make sense, make recommendations when I see a better approach, and take ownership of the work I'm responsible for. If you've got a Flutter app that needs someone to own it, not just implement tickets, I'd like to hear about it. Best regards, Matthew Olayemi Emmanuel
