What I'm looking for

I'm open to remote opportunities building scalable Flutter mobile products and Java backend services, especially for fintech, payments, and enterprise applications. I value distributed collaboration, reliable CI/CD, clean architecture, and shipping high-quality production systems.

I've led development of Swwipe Financial Services' NFC-enabled Flutter POS platform, improving transaction speed by 40%, adoption by 25%, and reducing transaction failures by 30% through integrated payment SDKs.

I build mobile and backend systems for fintech, payments, and enterprise applications using Flutter, Dart, Java, Spring Boot, REST APIs, and ISO8583 transaction processing. My work includes resilient notification, retry, and webhook systems for high-volume payment operations.

Across Sterling Bank, Ajeo, Biomach Technologies, AddlioTech, and Envizien, I've delivered financial and enterprise applications used by thousands of users. I've reduced crashes, modernized legacy architectures, built reusable components, and improved release quality through testing, CI/CD, Clean Architecture, and disciplined code reviews.

I'm comfortable collaborating with distributed product, design, and backend teams to take production applications from concept through reliable release.
