At London Stock Exchange Group, I migrated GitLab from the Omnibus monolith to the cloud-native Helm chart on EKS, adding pgBouncer in production and improving PostgreSQL connection efficiency by 90%. I also built the production Amazon DocumentDB platform with Terraform and automated an EBS migration that lowered AWS costs by 30% with zero downtime.
I migrated production projects from Jenkins and Bitbucket to GitLab CI/CD, cutting pipeline time by 60%, and delivered four serverless AWS projects for the stock market. Earlier, at Vodafone Intelligent Solutions, I built a Python and Bash workflow that cut server deployment time by 90%; I also taught Java labs as an Undergraduate Teaching Assistant.
