NigeriaWhat I'm looking for
I’m a Mobile Engineer with over 4 years’ experience specializing in developing, maintaining, and optimizing cross-platform mobile applications with Flutter. I focus on delivering secure, fast transaction flows and clean, conversion-friendly user experiences.
As Lead Mobile Engineer at Flipex Technologies (2024–Present), I designed and developed a high-performance Flutter app for gift card and crypto to fiat conversion. I integrated secure blockchain and payment APIs, optimized architecture to handle high transaction volumes, and improved UI/UX in collaboration with designers to boost engagement and conversion rates.
Previously at 1app Inc. (2022–2024), I built and maintained a financial services app for bill payments and local and cross-border transfers. I developed a multi-gateway payment integration system unifying Stripe, Paystack, and Flutterwave, enhanced transaction processing speed through optimization, and partnered with backend engineers to implement secure, scalable API integrations.
