Front End Developer

Iʼm a systems-minded technical lead with an unusual path: physics background, medical physics in oncology, then into engineering, QA and release leadership, and eventually frontend architecture and platform work. I build real systems, not just features. Iʼve designed and shipped products from zero in both startups and large platforms — including co-building the open-source blockchain explorer frontend now used by thousands of chains. My work usually sits at the intersection of architecture, product reality, and engineering execution: turning unclear ideas into structured systems, defining how parts connect, and making sure things stay reliable as they grow. Iʼm most useful in ambiguous environments where something needs to be figured out, organized, and moved forward. I prefer small, fast loops and shipping practical solutions. Recently Iʼve also focused on integrating AI tools into workflows in a pragmatic way, to make systems and teams move faster without adding unnecessary complexity.
