Maksym Kryvokhyzha

@maksymkryvokhyzha

Software Engineer at ArcelorMittal Kryvyi Rih who integrated railcar recognition and delivered MQTT processing for over 1,000 messages per second.

At ArcelorMittal Kryvyi Rih, I developed an Incoresoft recognition system integration service for railcar reweighting, handling API queries and recording received data in a database. The system was implemented on two scales and later expanded to other sites.

I also created and optimized an MQTT publisher that processed over 1,000 messages per second, with request-response functionality and data history retrieval. I modernized .NET software, ported APIs to Go, and implemented Jenkins CI/CD pipelines that decreased deployment times by 50%.
