What I'm looking for

I'm looking to build secure, scalable enterprise products where I can contribute across .NET, Java, frontend development, cloud delivery, and AI-integrated workflows while collaborating closely with engineering and business teams.

At ADP, I independently delivered the award-winning TDS Gross-Up payroll flow end-to-end, from the Angular UI to C#/.NET calculation engine integration.

I've modernized 40+ legacy ASMX services into RESTful APIs, remediated 200+ SQL injection vulnerabilities, and improved throughput 3× through asynchronous processing and query optimization. I also built and deployed an AWS-based AI developer tool connecting Jira, Confluence, and Bitbucket through secure, context-aware LLM API orchestration.

Previously at Fidelity Investments, I rebuilt Microsoft's PICT test tool with Java Spring Boot and React, improving test-modeling efficiency by 70%. I've also scaled Kafka performance-testing capacity by 10× and automated CI/CD delivery with Jenkins, Docker, and Git.
