  • Bridges research, backtesting, and production execution

• Solver: Advanced liquidity mapping and route evaluation supporting multiple solving and market-making strategies.

  • Built on Tycho with a custom liquidity mapping layer
  • Evaluates over 1,000 routes per second
  • Multi-chain and multi-protocol route discovery

• Solving Integration: Integrations with UniswapX, 1inch, and CoW Protocol.

• Liquidity Management: Intent-driven liquidity and resource management infrastructure.

• DeFi Research: Uniswap v4 Hooks, intent-based execution, solving research, and protocol experimentation.

I'm John Whitton, a software engineer, architect, technical leader, and entrepreneur working at the intersection of:

• Trading & Market Infrastructure
• Financial Infrastructure
• Payments & Settlement
• Distributed Systems
• Blockchain Protocols
• Engineering Leadership

My experience spans hands-on engineering, architecture, technical strategy, and engineering management, with a track record of building platforms, scaling teams, and delivering complex technical initiatives.

I enjoy identifying research gaps, building working systems, and helping organizations move from ideas to production.

Research and prototypes are developed through the jincubator organization.
