Experience

CI/CD Pipeline Implementation

I implemented a CI/CD pipeline from the ground up using GitHub to automate testing of new code, ensuring operational compliance before merging changes into the production codebase. This significantly reduced the number of bugs and issues reaching production. My work included developing automated tests and auto-publishing results to a webpage for management review.
