Architected a custom dynamic content caching strategy using a third-party CDN to front AWS infrastructure, slashing AWS data egress fees and reducing origin load by 25%.
Slashed customer environment provisioning time from 30 minutes to under 5 minutes by developing a Python serverless onboarding API utilising AWS Lambda and API Gateway.
Built and operated hardened production Amazon EKS environments, managing secure RBAC, ingress controllers, autoscaling, and node lifecycles to guarantee infrastructure reliability and scalability.
Engineered an Ansible powered Internal Developer Platform (IDP) that automated Docker provisioning with self-configuring reverse proxies, automated SSL renewals, and container self-healing.
Applied a defensive engineering mindset to production operations, treating every infrastructure update as a potential failure vector; designed automated rollback mechanisms and strict canary testing that significantly minimised deployment blast radiuses.
Provisioned and managed multi-environment AWS infrastructure using modular, reusable Terraform code, successfully eliminating configuration drift and enforcing deployment consistency.
Automated CI/CD and GitOps delivery via GitHub Actions and Argo CD, shifting security left by embedding policy engines, SAST, DAST, and container vulnerability scanning into the release pipeline.
Eliminated repetitive operational tasks by developing a comprehensive library of reusable Python and Bash scripting tools, streamlining troubleshooting and incident response triage.
Maintained 99.99% application availability by engineering comprehensive monitoring and alerting topologies across AWS and EKS environments using Prometheus, Grafana, and CloudWatch.
Guaranteed an aggressive 1-hour RPO and 30-minute RTO by implementing automated hourly backup pipelines and regularly executing simulated disaster recovery restore workflows.
Developed a Django based customer onboarding platform integrated with Stripe payments, seamlessly handling 2,500+ monthly active users and streamlining registration pipelines.
