Job Success
Lagos Island, Nigeria - 7:23 pm local time
That's how I work. I'm a FlutterFlow developer who turns Figma designs and app ideas into production-ready mobile and web apps with real backend architecture, not just a pretty UI wrapped around a database.
Send me your Figma file, existing FlutterFlow project, or even just your idea. I'll reply with a specific plan, not a sales pitch.
WHAT I BUILD:
🔹 SaaS platforms dashboards, subscription logic, admin panels, multi-user roles
🔹 Marketplaces & booking platforms real-time availability, payments, ratings, two-sided user flows
🔹 E-commerce apps cart, checkout, payment integration, order management
🔹 FlutterFlow rescue work inherited a broken or abandoned project? I audit and fix it
HOW I WORK:
🔹 Firebase/Supabase backends structured properly from day one, most cost and performance problems come from bad data modeling, and I catch that before it becomes your problem
🔹 Custom Dart/Flutter code where FlutterFlow's visual builder hits its limits
🔹 Stripe, RevenueCat, and third-party API integrations
🔹 Clear communication you'll know what's happening at every stage, not just at delivery
MY TECH:
Mobile: FlutterFlow • Flutter • Dart • Figma-to-App
Backend: Firebase (Firestore, Auth, Cloud Functions) • Supabase • Stripe • RevenueCat • REST APIs
Launch: App Store • Google Play • TestFlight • Push Notifications • In-App Purchases
FREQUENTLY ASKED QUESTIONS:
❓ Can FlutterFlow really build production-ready apps?
Yes : when custom code fills the gaps where the visual builder can't. I don't ship prototypes with hidden limits; I ship apps meant to go live and stay live.
❓ Will my Firebase bill stay under control?
Most cost spikes come from bad Firestore structure — nested subcollections, unbatched reads, missing indexes. I design around these issues upfront instead of fixing them after your bill spikes.
❓ Can you integrate Stripe or in-app purchases?
Yes : Stripe Checkout, subscriptions, and webhook-driven logic, plus RevenueCat for iOS/Android in-app purchases.
❓ Can you connect custom REST APIs or third-party tools?
Yes. When FlutterFlow's built-in API blocks aren't enough, I write custom Flutter/Dart code to handle authentication, pagination, and error handling properly.
❓ Do you handle App Store and Google Play submission?
Yes: end-to-end, including TestFlight setup and handling rejections if they come up.
❓ Will I own my project and code?
100%. It lives in your FlutterFlow account. You own the design, logic, and export rights. No lock-in.
❓ What if my current FlutterFlow project is already broken?
Send it over I'll audit it before you pay for anything. Most half-finished builds can be salvaged faster than starting from scratch.
❓ How do we start?
Message me with your Figma file, current project, or idea, and I'll respond with a specific plan for your app not a generic pitch.
HOW IT FEELS TO WORK WITH ME:
Regular updates so you're never wondering what's happening. Honest pushback if something in your plan will cause problems later, instead of quiet shortcuts that bite you after launch. Full documentation and handoff, so you're never dependent on me to make basic changes.
YOUR FREE PROJECT REVIEW:
Send me your Figma file, existing FlutterFlow project, or your idea. No obligation if it's a good fit, we move fast.
