Pipeline Studio lets teams define build and deploy workflows without YAML. I led the React front end and the workflow engine integration. A drag-and-drop workflow editor, GitHub integration, and a Node service that compiles graphs into runnable CI configs.

About
I ship products end-to-end, from schema design to polished UI. My recent work focuses on tools that help developers move faster without sacrificing quality.
Outside of code, I write about system design and mentor early-career engineers on portfolio and interview prep.
