About

I help banks and insurers move business-critical systems to AWS securely, cost-effectively and without disrupting the business, and I'm increasingly using agentic AI to take repetitive engineering work off teams' plates. Over 10 years at Societe Generale and Torry Harris Integration Solutions, I've grown from building Java microservices to designing and leading the cloud platforms they run on. Today I lead a team of 20–25 engineers where application architecture, platform engineering and cloud cost optimisation meet. What I've delivered: → Migrated 15+ services from on-premises to AWS ECS Fargate, cutting infrastructure costs by 30% → Built Amazon Bedrock AI agents that trace production issues from CloudWatch logs and raise GitHub pull requests with fixes, with a developer approving every change → Built an open-source vs. commercial business case that delivered 100% ROI within 4 years → Modernised legacy monoliths into Spring Boot microservices: 60–70% fewer deployment dependencies, 30–40% faster time-to-market → Scaled the BIMA mobile insurance platform to 100+ TPS across 5+ countries → Built a gamification platform for a group-wide Tech & AI Day with 1,000+ participants How I work: I weigh cost, resilience, security and scalability like an architect, but stay hands-on, so the designs I propose are ones I know can be built and run. Currently pursuing: AWS Certified Solutions Architect – Associate and AWS Certified Generative AI Developer – Professional. Open to Cloud Architect, Platform Engineering Lead and Technical Lead roles in financial services and insurance. Core skills: AWS (ECS Fargate, EKS, Lambda, Step Functions, Bedrock) · Infrastructure as Code (CloudFormation, Terraform) · CI/CD & DevSecOps (GitHub Actions, Jenkins, Docker, Kubernetes) · Java 17 · Spring Boot · Microservices · Kafka · FinOps
