What I'm looking for

I'm looking to own design-to-production UI work, partner with product and engineering, build maintainable enterprise applications, and apply Generative AI through practical Angular and Python solutions.

I led Angular v14-to-v20 migration work at Ardent Mills, refactoring enterprise Core and Prism applications, modernizing Material components, improving load times, and building Azure DevOps CI/CD pipelines.

At Thermo Fisher Scientific, I built an enterprise Generative AI portal and Python prototypes using Streamlit, Flask, FastAPI, OpenAI, Azure OpenAI, Flowise, GraphQL, and Neo4j. Across banking, life sciences, government, and enterprise products, I turn complex workflows into maintainable, accessible UI experiences.
