What I'm looking for

I’m looking to build high-impact web and cross-platform mobile products, working in an agile team where I can own pixel-perfect UI, scalable APIs, and reliable integrations—while continuously improving performance and maintainability.

I am a skilled web and software developer with more than 5 years of experience building web apps and cross platform mobile applications. I specialize in React, Next.Js, and React Native (Expo) to deliver dynamic, responsive, pixels-perfect user interfaces.

I design efficient global state management with Zustand/Redux, optimize data fetching with React Query (Tanstack), and build scalable RESTful APIs with Django and Django REST framework. I’ve integrated payment gateways (Paystack, Flutterwave, Stripe, Apple Pay, Google Pay) and have led teams to deliver client-focused web and mobile dashboards, including SAAS e-learning and ERP-style systems in an agile environment.
