Blockchain
infrastructure

Two years of full-stack engineering for crypto-adjacent startups — internal dashboards, on-chain analytics, custodial UX, treasury tooling. Transitioned out before pivoting to scientific tooling.

Scope.

Built tooling for several crypto-native teams: dashboards, treasury views, transaction explorers, and internal control planes. Mostly TypeScript on the frontend, Node services on the back end, with deep integrations into chain RPCs and indexers.

Takeaways.

The cycle wound down for me in 2023; I moved on before the broader market turned. The engineering reps — high-stakes financial UX, latency-sensitive systems, observability — translated directly into how I now build scientific software.
