You will get a scalable multi-vendor marketplace SaaS platform
Project details
I help founders and growing businesses turn marketplace ideas into scalable SaaS platforms that are built properly from day one. This is not just a basic website build. I design structured multi vendor systems with clean architecture, secure payment integration, and a solid admin backend that gives you full control.
Whether you are launching a service marketplace, product marketplace, or subscription based platform, I focus on performance, automation, and long term scalability. Every project starts with clear planning, database structuring, and feature mapping so your platform does not break when you scale.
You will get a responsive web application, vendor dashboards, Stripe integration if required, commission logic, and a streamlined user experience built for growth. I communicate clearly, deliver on time, and build systems that are reliable and easy to manage.
If you are serious about launching a real marketplace business, not just testing an idea halfway, this is for you.

AI Integration Developer | ChatGPT | Flutter | Web Apps & Mobile
Lagos, Nigeria - 7:37 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:
✅ AI Chatbot Development, ChatGPT-powered bots with memory, context, and custom conversation logic built around your users
✅ OpenAI and LLM API Integration, GPT-4, Claude, Gemini and other models embedded cleanly into your web or mobile app
✅ Flutter Mobile App Development, cross-platform iOS and Android apps with AI features that feel native, not bolted on
✅ Full Stack Web Application Development, React, Node.js, REST APIs, and database architecture built to grow with you
✅ SaaS MVP Development, from your idea to a production-ready platform complete with subscription billing, user auth, and dashboards
✅ AI Automation, connecting your tools, CRMs, and data pipelines so your team stops doing manually what a system can handle
✅ Bubble Development, fast no-code SaaS builds for founders who need to move quickly without sacrificing structure or scalability
✅ 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.
