At dRPC, I was the first engineering hire and built the initial customer web application for its blockchain RPC infrastructure. I owned the PostgreSQL data model, tRPC API, ClickHouse integrations, and React/Next.js UI from production launch onward.
I've delivered end-to-end product areas including team management, authentication, billing, payments, and analytics. I led a live multi-tenancy rebuild with invitations, role permissions, reusable authorization middleware, and a no-downtime user migration.
I built enterprise invoicing workflows with server-side PDFs and email delivery, integrated Paddle subscriptions and crypto top-ups, and created an x402 endpoint for agent payments. I also built customer and foundation analytics, fixed out-of-memory failures, and added caching for expensive ClickHouse aggregates.
Previously, I built clinical-research platforms at Prometheus Research, including survey interfaces and a medical cohort builder. I also solo-built learn-sql.dev, an interactive SQL learning platform running real PostgreSQL queries.
