- Developed an internal tool for the Lambda Control Plane Functions team to automate the categorisation and analysis of tickets in a large backlog, increasing observability for customer-impacting tickets.
- Developed a CLI tool using Python to bulk analyze tickets in-depth using AWS Bedrock and iterative reasoning with an internal MCP server. This also generates summary documents for users.
- Created a TypeScript and React web app with a Lambda backend to categorise tickets and display categorisation results for the entire backlog. This helped reduce the team's 600+ ticket backlog by 21%.
