7+ years designing and delivering production-grade distributed systems at scale — from Oracle's core ML analytics platform to cloud-native startup infrastructure. I architect backends that hold under pressure and ship features that matter.

WHO I AM

01

"I care deeply about writing software that is fast, observable, and maintainable — and about delivering real-world impact through what I build."

I'm a Senior Full Stack Developer based in Glasgow with over 7 years of experience designing and scaling enterprise-grade systems across fintech, healthcare, and analytics.

My background spans Java backend engineering, cloud infrastructure on AWS, and full-stack delivery using React and Angular — from Oracle's core ML platform to production-grade traceability systems at startups.

I hold an MSc in Data Analytics (Distinction) from the University of Strathclyde, giving me a strong foundation in machine learning that complements my systems expertise.
