At Amazon, I modernize production payment and Kindle services used by millions of global users. I resolve long-standing technical debt, rebuild integration testing, improve authentication, and own production reliability as the Kindle Annotations Service SPOC.

I built a CLI-driven AI agent using MCP to connect Jira with internal service APIs, reducing cross-functional workflow execution from two hours to five minutes. I also re-architected global service infrastructure with AWS CDK, reduced false-positive alerts by 40%, and delivered CloudWatch logging and JDK 17 migrations.

Previously at Comcast, I deployed an enterprise AI chatbot with Django and Vue.js that unified knowledge from Jira, Confluence, Amazon S3, and Elasticsearch. The platform automated routine workflows and reduced team workload by 35%.

I began at Comcast supporting production operations for 57M+ customer devices, building Python, Flask, Angular, and Docker tools that reduced operational workload and improved release reliability.
