Beyond the portfolio

Sample Work

A few things built for their own sake — proof I can execute end-to-end, not just talk about it. Frontend, backend, and AI automation each get their own space below.

Frontend

A fully independent storefront UI

A small e-commerce demo — its own brand, its own theme, real add-to-cart and checkout interactions. Built to look nothing like this portfolio.

System architecture & data modeling

Diagrams for a production-style e-commerce backend: service architecture, a checkout request flow, and the underlying data model.

AI agent & automation workflows

How an LLM-driven agent routes requests, calls tools, and hands off to a human — plus a support-ticket triage pipeline.
