   Senior Software Engineer

   Hyblockcapital

   Hyblock Terminal · API v2

   • Defined the v2 metric API as the contract the terminal, alerts, and external clients share: 100+ REST endpoints for orderbook, open interest, funding rate, liquidation levels, and whale positioning, with coin, exchange, and timeframe down to 1m as the only query model.
   • Designed the cross-exchange liquidity layer behind bidAsk, bidAskRatio, combinedBook, and globalBidAsk, normalizing 10+ venue books into one global view and keeping x-api-key auth on the boundary so keys never reach the client.
   • Built a Rust migration pipeline that streams billions of historical rows into the analytics store in batches, instead of loading the table into memory.
   • Set the MongoDB grain for openInterest, fundingRate, and liquidationHeatmap: time-bucketed series and aggregations that answer a 1m window from the index, not a scan of the full history.
   • Run ingestion and the API on AWS with Docker, Lambda, API Gateway, and ECS. Kafka carries live book and liquidation updates; Redis sits in front of the hot metric reads.
