Running

xochi.fi : private exchange & friendly dark pool on Ethereum. ZK compliance via ERC-8262, the Zero-Knowledge Compliance Oracle standard we co-authored. axol.io runs the infra. Raising. The open infrastructure side is funded through Giveth.

Learning

Current reading list
  • MEV/HFT: searcher strategies, arb, liquidations, backrunning, latency
  • Quant: solver rebalancing, cross-chain inventory, execution optimization
  • Prediction markets: applying the quant work to Polymarket
  • ZK compliance: ZKSAR proofs, sanctions screening, provider weight tuning
  • OTP internals: gen_server, supervisor restarts, distributed Erlang

Location

Remote (Europe/Madrid). Remote.

Open to consulting. Ethereum protocol, ZK circuits, validator infra. Background.
