• Implemented crucial features to enhance the proprietary low-latency C++ software used to trade on cryptocurrency exchanges.

• Built trading systems to trade on centralized exchanges via REST, WebSocket, FIX protocols.

• Architected and implemented dynamic processor affinity selection to minimize thread access across distant NUMA nodes.

• Designed and implemented custom protocols to trade on various cryptocurrency DEXs (e.g. Serum) via blockchain technology.

• Improved the security of the trading systems by building API key management systems and low-latency distributed signing services.
