About Me

// Background

I build software that is meant to be used, not just studied.

My main focus is mobile development, backend systems, and AI-powered tools. I enjoy taking ideas from concept to working product, whether that means designing a SwiftUI app, building a Rust API, connecting cloud infrastructure, or integrating AI features into a practical workflow.

I have a BSc in Computer Science from the University of Greenwich, where I developed projects across software engineering, mobile development, backend systems, machine learning, and full-stack application design.

Before software development, I worked for many years in regulated operational environments, including senior roles within the casino industry. That experience taught me accuracy, accountability, discipline, and how to perform well in high-pressure situations — qualities I now bring into engineering work.

// The Journey

2020–2026

Back to Roots & Uni

Returned to my true passion. Earned a BSc in Computer Science from the University of Greenwich and fully committed to software development — iOS, backend, and AI-powered tools. Building and shipping production apps.

2000–2020

Professional Career

17+ years in regulated gaming environments across London and Lithuania. Rose to Pit Boss in Lithuania, then relocated to the UK and worked back up to Senior Dealer at Grosvenor Victoria Casino (10 years). Managing tables, training staff, and maintaining compliance under strict regulatory oversight.

1994–2000

Where It All Began

Self-taught computers, programming, and networking. Built PCs and explored software from the ground up — the foundation of a lifelong passion for technology.
