01

AI platform engineering

Building the frontend layers of AI products — from chat interfaces and prompt UIs to tool dashboards and streaming response rendering.

Designing and delivering scalable MFE systems for global products. One year as delivery architect on a cross-team micro frontend + microservice platform.
