Work history
Senior DevOps / Platform Engineer
CACI Ltd (Cyber-Duck)
London
2024.01 - 2026.04
- Reduced infrastructure costs by approximately 30% by leading migration of enterprise client workloads from AWS Elastic Beanstalk to containerised platforms on Amazon ECS (Fargate), improving scalability, resilience, and deployment consistency.
- Improved deployment reliability and release velocity by 40% by designing and implementing reusable CI/CD pipelines using GitHub Actions, GitLab CI, and Buddy, incorporating automated testing, validation, and structured environment promotion workflows.
- Strengthened AWS security posture across multi-account environments by building a custom cloud security auditing platform based on Prowler, automating IAM least-privilege reviews, compliance checks, and security reporting.
- Enabled secure non-production testing for regulated clients by engineering a production-to-non-production data anonymisation pipeline, reducing data preparation time by 60% while ensuring GDPR compliance.
- Improved platform consistency and workload onboarding speed by 50% by developing reusable Terraform modules (VPC, IAM, ECS services, RDS, KMS) with remote state management using S3 and DynamoDB locking.
- Implemented centralised logging, CloudWatch monitoring, and alerting standards across containerised workloads, reducing incident response time by 35%.
- Conducted technical design reviews and mentored engineers, improving infrastructure code quality, security guardrails, and DevOps best practices across delivery teams.
- Platform Engineering Contributions
- Designed shared AWS platform components aligned to platform engineering principles, balancing developer velocity with governance and operational resilience.
- Enabled self-service infrastructure provisioning through reusable Terraform modules and golden path deployment templates.
- Contributed to multi-account AWS architecture using AWS Organizations and centralised logging strategies to enforce guardrails.
- Supported containerised workloads aligned to Kubernetes and EKS architectural patterns and cloud-native best practices.
