Principal Software Engineer with 12+ years of hands-on experience leading the design, delivery, and long-term operation of distributed backend platforms that power business-critical workloads at scale. I specialise in event-driven architectures, microservices, and cloud-native platform design — from initial architecture through CI/CD automation, Infrastructure as Code, containerisation, and observability — taking full lifecycle ownership of systems built to be fast to deploy, reliable under pressure, and cost-efficient to run. Whether migrating legacy monoliths to modern microservices, defining platform strategy with stakeholders, or getting deep into code, I bring the same rigour — mentoring engineering teams, driving DevOps and Agile adoption, and raising the technical bar across organisations to turn complex technical challenges into scalable, maintainable solutions that deliver measurable business value.
