Profile

Architecture leadership for high-stakes platforms.

I am a Principal Solution Architect and Technical Architect with deep experience across Microsoft Azure, event-driven systems, API governance, cloud-native modernisation, and executive-facing technology strategy.

My work is strongest where architecture has to carry real operational weight: regulated financial services, national-scale government platforms, high-throughput processing, security governance, and long-running legacy transformation.
