Web and Mobile Software and Solutions Architect and Engineering Lead

Actions

Software Architect and Engineering Lead with 20+ years building and scaling web and mobile platforms. I specialise in JVM-based backend systems, mobile development (Android, Flutter), and the architecture that connects them.

Most recently, I led the architectural transition of a global online dating platform from legacy monoliths to .NET microservices with React frontends, while continuing to operate the existing JVM-based API platform serving over 1 billion interactions per month. I also introduced an AI-assisted software engineering program, integrating tools like Cursor and AI agents into team workflows. I lead distributed engineering teams, own DevOps pipelines, and bridge the gap between product strategy and technical execution.

My work spans hands-on development, system design, and team leadership, often all three simultaneously. I'm equally comfortable debugging a race condition in production, designing a multi-region deployment strategy, or mentoring engineers through a complex refactor.

I run my consulting practice through Ventego Creative, which has allowed me to work with organisations ranging from startups to enterprises including Vodafone, Citibank, Siemens, Cupid Media, Raygun, and DistroKid. I also maintain several open-source SDKs (Android, Flutter, Ruby, Python, Node) for Raygun's error tracking platform.

Beyond client work, I'm an active conference speaker (Droidcon, Android Makers, CFCamp, and others), a technology writer for European IT publications, and have been co-organising community meetup groups since the start of my career. I hold a Master's degree in Mathematics and Computer Science and am currently pursuing a Master's in Data Science.
