Hire the Best API Developers
in Nigeria

Need a FlutterFlow mobile app that works like a real product, not just a few screens connected together? I help founders, startups, small businesses, and product owners turn app ideas into working iOS and Android MVPs using FlutterFlow, Firebase, Firestore, Supabase, Stripe, APIs, and clean mobile UX. My focus is on building mobile apps with real user flows, backend logic, and the core features needed to test, launch, and improve a product. Whether you are building a fintech app, marketplace, subscription app, community app, booking app, delivery app, AI-powered mobile app, or internal business tool, I can help you structure and build the MVP properly. I can help with: FlutterFlow mobile app development iOS and Android MVP development Firebase and Firestore backend setup Supabase backend setup User signup and login User authentication User profile creation Dashboards and tracking screens Stripe and payment gateway integration Subscription and in-app purchase flows API integration Push notifications In-app search Chat and messaging features Map integration and location-based services Admin dashboards Mobile app bug fixing Mobile app testing Firebase cleanup and app flow improvement UI/UX prototyping for mobile apps If your app needs users to create accounts, make payments, join groups, search content, message other users, track activity, view dashboards, receive notifications, or interact with backend data, I can help you build the right structure. Many app projects fail because the first version is either too basic, too messy, or too disconnected from the business goal. The screens may look good, but the authentication breaks, the database is poorly structured, payment flow is unclear, dashboards do not update correctly, or the app becomes difficult to improve later. That is the problem I help solve. My process is practical. I first clarify the app goal and user flow, then map the screens, define the backend structure, build the frontend in FlutterFlow, connect Firebase or Supabase, set up authentication, integrate APIs or payments where needed, test the core actions, and clean up the flow before handoff. I work best on apps that need real business logic, such as: Fintech MVPs Savings circle or ROSCA apps Marketplace apps Subscription apps Community apps Booking apps Delivery apps Learning apps AI chatbot apps Customer portal apps Mobile dashboards Internal business apps Location-based apps For example, if you are building a savings circle app, I can help structure user signup, verification, create/join group flows, weekly payment tracking, dashboard views, security deposit logic, member status, payment records, and Stripe or payment gateway integration. If you are building a marketplace app, I can help with user profiles, listings, search, filters, chat, map/location features, saved items, admin control, and backend data structure. If you are building a subscription or membership app, I can help with authentication, subscription access, user dashboards, payment flows, push notifications, and account management. If you already have a FlutterFlow app, I can also help fix broken Firebase connections, authentication issues, Firestore query problems, payment errors, navigation bugs, slow user flows, API issues, dashboard data problems, and mobile responsiveness issues. Tools I work with include FlutterFlow, Flutter, Dart, Firebase, Firebase Cloud Firestore, Firebase Realtime Database, Supabase, Stripe, REST APIs, OpenAI API, push notifications, Google Maps API, and mobile app testing workflows. You can expect clear communication, structured app planning, clean FlutterFlow builds, reliable backend setup, careful handling of user data, payment/API integrations that match the user flow, testing before handoff, and practical feedback on what should or should not be in the MVP. I am a good fit if you need a developer who can help with both the build and the structure behind the build. I am not here to just connect random screens. I focus on building mobile apps that users can actually sign into, use, pay through, interact with, and test in the real world. Send me a message with your app idea, feature list, wireframe, or current app link, and I will help you map the best way to build it.

Your web app is either half-built, broken, or you're stuck managing two developers who don't talk to each other. I solve that one developer, full ownership, complete delivery. I help startups, small business owners, and founders build production-ready web applications using React, TypeScript, Node.js, Python, FastAPI, and MongoDB. I own the entire build: responsive UI, backend logic, REST API, database design, and live deployment on Vercel and Render. So you never have to coordinate multiple people or chase someone who disappeared mid-project. Clients come to me when: ▸ They need a full web app built but can't manage separate frontend and backend developers ▸ A previous developer abandoned the project or delivered broken, unmaintainable code ▸ Their existing app is slow, crashing under normal traffic, or returning wrong data ▸ They're selling manually on WhatsApp or Instagram and need a real online store ▸ They have live data from an API or spreadsheet but no clean way to visualise it ▸ They need a backend built so their mobile app or frontend actually has something to connect to What I build: ▸ Full-stack web applications: end-to-end, from first line of code to live deployment ▸ E-commerce platforms: product catalogue, cart, payments, admin dashboard, delivery system ▸ REST APIs: clean, documented, connected to your frontend or third-party services ▸ Data dashboards: live data pulled from APIs and displayed in one interactive interface ▸ React frontends: fast, mobile-first, responsive across every device ▸ MongoDB backends: schema design, authentication, business logic, scalable architecture Projects I have shipped and deployed: a Stock Analysis Dashboard pulling live financial data including price charts, market cap, revenue, EPS, news sentiment, and trending keywords, a Species Catalogue search application with biological API integration, and a full e-commerce platform for a Nigerian beauty brand with payments, user accounts, newsletter system, admin panel, and Nigeria-wide delivery. All live. All built alone. I write clean, modular code with Git version control. I communicate at every stage. I do not disappear after delivery. If your project needs a developer who takes complete ownership and ships something real users can actually use, send me a message or invite me to your job. I respond within hours.

I build production AI Apps and Saas platforms for founders, Start-ups and people who needs to move fast. Founders and early-stage startups hire me when they need a production-ready AI app or SaaS platform live fast not in months, but in weeks. I've built an AI-powered home listings platform for a real estate startup in 5 days, migrated a founder's Base44 SaaS app from demo to scalable multi-tenant architecture in 3 days, and resolved a critical Supabase/PostgreSQL backend failure for a live app the same day it was reported. If you need a real product and website fully deployed, user-ready, and generating revenue from day one that's exactly what I build. I handle the full stack so you don't have to manage any of it: frontend, backend, database architecture, API integrations, AI features, and cloud deployment. Your customers can sign up, pay, and start using your platform immediately while you focus on growing your business instead of managing tech stacks.
