16+ years bridging Enterprise IT Infrastructure, Commercial Operations Leadership & Cloud Software Engineering to build high-reliability production systems in the UK.
I am a pragmatic, business-first Systems Architect and Full-Stack Software Engineer based in Birmingham, UK, with a 16+ year track record (since 2010) across cloud software engineering, database architecture, data analytics, and mission-critical IT operations.
What sets me apart is End-to-End Domain Ownership: I don't just write code in isolation from tickets—I have led real-world commercial operations on the ground in the UK. I identify revenue bottlenecks, compliance risks, and operational friction, and I engineer complete, resilient production platforms from database schema and Linux kernel tuning to AI-powered executive interfaces.
