What I Delivered
- Completed and peer-reviewed Angular UI components for the staffing platform

- Implemented secure CI/CD pipelines with 'build once, deploy many' binary workflows
- Introduced Rancher for containerised deployments, replacing fragile manual processes
- Created local development environments with Docker Compose for all services
- Deployed selected services to AWS Lambda, later reverting latency-sensitive workloads to containerisation due to cold start performance issues
Outcomes
- Enabled the UK’s largest temp staffing portal to run on a modern, containerised infrastructure
- Reduced build pipeline vulnerabilities and improved deployment reliability
- Optimised system performance by aligning workload types to the most suitable compute model
- Enhanced developer productivity through repeatable and efficient delivery pipelines
