- Version Control: Expert knowledge of Git and standard collaborative development workflows.
Bonus Points If You Have:
- Experience building or maintaining core infrastructure for digital asset trading, order matching engines, or liquidity bridges.
- Familiarity with decentralized finance (DeFi) primitives or automated market makers (AMMs).
- A strong public GitHub profile showing open-source contributions or live, verified smart contracts on-chain.
