About

Professional summary

I am a full-stack developer and mobile app specialist with over seven years of experience delivering web, mobile, and backend solutions for clients across fintech, logistics, real estate, hospitality, education, and other industries.

I build cross-platform mobile applications using FlutterFlow and Firebase, alongside scalable REST APIs and web platforms using Node.js, Express.js, PHP, MySQL, Bootstrap, and WordPress. My work includes app architecture, authentication, payment systems, dashboards, e-commerce, and customer-facing digital platforms.

I have delivered more than 300 client projects through my company, Perfect Website Builders. I manage the full product lifecycle, from requirements gathering and solution design through development, testing, deployment, app-store release, and post-launch support.

I am experienced in integrating payment gateways including Flutterwave, Paystack, and Korapay, as well as Google Maps, VTU/airtime services, webhooks, and third-party APIs. I have also deployed backend systems on Render and Railway and maintained reliable production services for growing user bases.

I am comfortable working remotely with international clients and distributed development teams. I am available immediately for full-time, contract, or freelance opportunities and can work flexibly across US, UK, and European time zones.
