Backend engineering

I built ChainGraph as a GraphQL subscription toolkit for indexing and streaming EOSIO and Antelope data. At Bitlauncher I built the EOS EVM indexer on viem event subscriptions and a dFuse stream, with Supabase for queries, aggregation, and realtime subscriptions.

Bitcash needed the matching engine to be the system of record: Hasura GraphQL APIs, a realtime EOS indexer with worker threads and binary deserialization, and PostgreSQL behind the exchange. Opyn keeps protocol state in a Ponder indexer over PostgreSQL so the trading interface reads it instead of reconstructing it in the client.
