What I'm looking for

I am looking for a collaborative environment that fosters innovation and offers opportunities for professional growth.

I am a Senior Mobile Engineer with extensive experience in developing and maintaining mobile applications across both iOS and Android platforms. My journey in technology began with a B.Sc. in Computer Science from Bells University of Technology, where I honed my skills in software engineering principles and agile methodologies. I have a proven track record of delivering complex projects on time and with exceptional quality.

In my current role at Pay4Me Inc, I lead a mobile team in architecting and developing the Pay4Me App using Flutter. I oversee the entire development lifecycle, from planning to release, while mentoring junior developers and ensuring high engineering standards through rigorous code reviews. My contributions have significantly improved user retention and reduced crash rates, showcasing my ability to analyze complex problems and develop innovative solutions.

Throughout my career, I have collaborated with cross-functional teams to deliver features that enhance user experience and drive engagement. I am passionate about mentoring the next generation of developers, having designed a Flutter learning curriculum and guided over 30 students in app development. I am eager to continue growing in a dynamic environment that values innovation and collaboration.
