Six years of indexers, SDKs and APIs for on-chain data. Every system snaps together from small, well-made pieces.
01 · sqd · python
The client library that streams indexed on-chain data straight into your Python pipeline. Designed the API surface, shipped it, wrote the docs.
02 · dexguru · python · clickhouse
Indexes on-chain events across multiple EVM chains — prices, trades, balances, new assets. Query, schema and caching work made retrieval 50% faster.
03 · dexguru · fastapi
Many trading providers behind one interface. Every request takes the most profitable execution route — a non-deterministic system with many moving parts.
04 · side project · pgvector
Ask questions in plain English, get answers from token and contract metadata via an LLM.
Lately at SQD: Flink jobs, ClickHouse sinks and a Python SDK. Before that — five years of DeFi data at DexGuru. On weekends: LLM experiments over on-chain metadata.
