What I'm looking for

I am looking for a role that fosters innovation, encourages collaboration, and offers opportunities for professional growth.

I am a Senior Backend Engineer and Technical Leader with over 4 years of experience in architecting scalable distributed systems and leading engineering teams. My journey has been marked by a proven track record of establishing technical directions, mentoring developers, and delivering robust solutions that serve thousands of users. I specialize in designing microservice architectures, API development, and implementing complex financial systems.

At Peerless SGC, I contributed to building Nigeria's first core banking application, SeaBaas, and provided technical oversight for high-throughput transaction APIs. My role involved leading multiple engineering teams, establishing technical standards, and conducting thorough code reviews to ensure code quality and system scalability. Previously, at Daba Finance, I played a pivotal role in developing a comprehensive backend architecture that currently supports over 20,000 active users, implementing technologies like GraphQL and Kafka to enhance system reliability and scalability.
