About

I've spent the last 5+ years making the web feel fast, clean, and effortless for users — and maintainable for the engineers who come after me.

Currently a Senior Experience Engineer at Publicis Sapient, where I build large-scale frontend applications using React, TypeScript, and Next.js for enterprise clients like CPPIB and Lloyds Banking Group.

I'm known for writing tests first, building reusable component libraries and custom hooks, standing up React/Next.js projects from scratch (CI/CD included), and turning complex data into clear visualizations.

Currently exploring AI Engineering alongside my frontend work, with hands-on RAG/LLM integration experience from the CPPIB Knowledge Initiative project.

Experience

5+ years building large-scale frontend applications for enterprise clients across banking, healthtech, and manufacturing.
