Experience

Engineering, markets, startups, and community mentorship.

Jul 2025 — Sep 2026

SDE, Developer Platform

Jupiter Exchange

Developer platform for Jupiter's swap and trading APIs (Ultra, Metis), used by high-throughput trading firms.

  • Built ClickHouse quote, execution, and slippage analytics for Metis and Ultra: billions of rows per day ingested (much of it arbitrage-bot flow) and processed with materialized views into developer and trading insights.
  • Worked on quote simulation pre-routing to improve Jupiter's slippage penalties for prop AMMs.
  • Built the Rust API gateway (microservices) in front of Jupiter's developer APIs, including the Ultra swap endpoints: API-key authentication, permissions, and firewalling.
  • Contributed gRPC/Geyser integrations to Beam, Jupiter's proprietary transaction lander.
  • Debugged Jupiter swap-API integrations and supported developer infrastructure for high-volume integrators including Binance, Robinhood, Uniswap, and Jump Trading.
  • Built the Jupiter API docs and release notes for the self-hosted Metis binary re-release.
