- Accelerated test coverage by leveraging AI to author 2,000+ lines of unit tests in under 3 days, achieving 90%+ coverage for 3 complex packages using Jest and React Testing Library.
- Built an internal Copilot AI agent leveraging architectural docs to help architects explore design options, clarify trade-offs, and accelerate architectural decision-making through conversational AI.
- Actively participated in code reviews, ensuring adherence to clean code principles and software design best practices.
