At JPMorgan Chase, served as primary frontend engineer for a multi-grid analytics workspace over datasets containing 100M+ rows and was promoted from Software Engineer III (Associate) to Lead Software Engineer (Vice President).

Experience

• Shipped Ingrid, a local-first hierarchical grid workspace for structured notes and projects, with IndexedDB persistence and paid cloud sync in production.
• Built Showdown Elo, a nightly MLB ratings product derived from 8M+ Statcast pitches; benchmarked the underlying models against betting markets and published the negative result.
• Designed and shipped both products end to end — product direction, data modeling, interface, deployment, automated validation — with AI coding agents assisting implementation.

• Served as primary frontend engineer during the product’s first year, building a multi-grid analytics workspace on a small, fast-moving team.
• Enabled users to explore, join, pivot, and retrieve datasets containing 100M+ rows.
• Kept every grid responsive over server-held data: virtualized scrolling fetches only the visible row window over WebSockets, backed by client-side caching and state management.
• Evaluated LLM workflows for legacy modernization and codified reusable project instructions, skills, and widget constraints for generated UI.

• Shipped an updated bus-ticketing system using React and Node.js as the primary implementation engineer on a four-person team.
• Developed scheduling, vaccination, appointment-reminder, and clinical workflow features integrated with eClinicalWorks and existing operational systems.

• Operated a specialty tea business serving retail and wholesale customers.
• Built internal database workflows for inventory, sales, and operations.
