Work Experience
Lead Software Engineer
Ford Motor Company
- Built an enterprise LLM-powered project management assistant using FastAPI, Google ADK, Vertex AI/Gemini, and RAG, enabling users to chat with organizational knowledge and execute actions across Jira, Confluence, and internal tools.
- Developed the AI agent runtime and product APIs for chat, conversation persistence, tool execution, user/team management, permissions, monitoring, and configuration, using PostgreSQL/Cloud SQL and Redis for persistent and session state.
- Automated a monthly dealer fraud-detection workflow in Python on GCP that standardized fragmented Excel data, replaced previously manual decision logic, cross-checked public vehicle registration records, and surfaced potential dealer-level fraud.
- Integrated generative AI into fraud reporting to convert structured risk findings into human-readable explanations and comments for Ford Credit business users.
- Developed an AI-powered vehicle recommendation service using Spring Boot, Vertex AI, and PostgreSQL/Cloud SQL, combining live model inference with cached recommendation data to reduce latency and unnecessary model calls.
- Built a Spring Boot fraud facade that normalized third-party fraud-provider results into a single, consistent API contract for downstream Ford Credit applications.
- Led development of Ford Credit's Online Credit Application and architected greenfield credit, lease-renewal, and prequalification applications using Angular, React, Java, and Spring Boot.
- Improved CI/CD pipelines using Tekton and GCP, shortening release cycles by approximately 25% while supporting zero-downtime blue-green deployments.
- Established TDD and automated unit, contract, integration, and end-to-end testing practices across front-end and back-end applications.
- Modernized and refactored a 20-year-old legacy backend, reducing technical debt and improving maintainability while mentoring junior engineers through XP and pair-programming practices.
