You will get a fast, scalable Progressive Web App for your business
Project details
Are you looking to launch an app experience without the heavy cost of native development? I help founders and growing businesses build fast, reliable Progressive Web Apps that feel like real mobile apps, but run seamlessly on the web.
I don’t just build pages, I build structured, scalable systems designed for performance, security, and long-term growth. Your PWA will be installable, responsive across devices, optimized for speed, and ready to scale as your users grow.
Whether you are validating an MVP, launching a SaaS platform, or upgrading an existing product, I focus on clean architecture, smooth user experience, and business-driven functionality.
If you want more than a basic website and need a high-performance web application built with clarity and precision, you are in the right place.

AI Integration Developer | ChatGPT | Flutter | Web Apps & Mobile
Lagos, Nigeria - 11:17 pm local time
I'm an AI Integration Developer specialising in AI-powered web and mobile apps for startups, SaaS founders. and growing businesses. I've spent the last four years doing one thing well, helping people turn product ideas into real, working systems that don't need to be rebuilt six months after launch.
I work across the full stack, from Flutter-based iOS and Android apps to React and Node.js web platforms, and I bring in AI capabilities that are structured, scalable, and actually useful to the people using your product every day. Not AI for the sake of a feature. AI because it makes your product better.
Here's what I build:
âś… AI Chatbot Development, ChatGPT-powered bots with memory, context, and custom conversation logic built around your users
âś… OpenAI and LLM API Integration, GPT-4, Claude, Gemini and other models embedded cleanly into your web or mobile app
âś… Flutter Mobile App Development, cross-platform iOS and Android apps with AI features that feel native, not bolted on
âś… Full Stack Web Application Development, React, Node.js, REST APIs, and database architecture built to grow with you
âś… SaaS MVP Development, from your idea to a production-ready platform complete with subscription billing, user auth, and dashboards
âś… AI Automation, connecting your tools, CRMs, and data pipelines so your team stops doing manually what a system can handle
âś… Bubble Development, fast no-code SaaS builds for founders who need to move quickly without sacrificing structure or scalability
âś… API Integration, Stripe, Firebase, Supabase, Twilio, and any third-party service your product depends on
What makes working with me different is how I start.
Before I write a single line of code, I sit with the architecture. I think through the database structure, the user flows, where the AI logic lives, and where the system needs to be able to scale. I've seen too many projects get rebuilt from scratch because nobody planned for growth at the beginning. That doesn't happen with me.
I've built subscription platforms, marketplace systems, custom CRMs, AI-assisted dashboards, and Flutter apps across multiple industries. My clients tend to describe it as working with someone who thinks like a co-founder, not just a developer they hired on a platform.
If you're building a web app, a mobile app, or a SaaS platform and you want the AI done right, scalable, clean, and ready for real users, send me a short message about what you're working on.
Let's build something worth building.
