Timken Steel Level 2 to 3 Interface
I developed a new service using C#, Kepware, and TCP/IP sockets communicating via TNet Strings (for condensed messaging) allowing software engineers to send commands to hardware on the continuously grown billet conditioning line; and get data back. The service is responsible for all level 2 communications on the production line. It reads in less than 1 millisecond.

AXS Software Platform

NoSQL Engine for Crypto Exchange Rates

I designed and built a custom in-memory NoSQL engine to store/read/write exchange rates for cryptocurrencies across different markets.

The implementation allowed for the independent scaling of read operations against the blockchain and analysis of market rates for arbitrage opportunities.
