About

I am a Staff Software Engineer with a First Class Honours MEng from University College London (UCL). My career is defined by a transition from deep native technical execution to high-level strategic leadership. Currently, I lead a team of 9 engineers at Betfanatics, where I architect Kotlin Multiplatform (KMP) systems integrated with custom CMS layers to drive the next generation of iGaming experiences.

I thrive on solving complex architectural challenges, whether it's modularizing large-scale codebases using SPM, migrating legacy Objective-C to modern Swift, or building serverless backends on AWS. Beyond the code, I am a dedicated mentor and recruiter, focused on building high-performing engineering cultures that bridge the gap between product vision and technical reality.
