  Hamburg, Germany I was focussed on improving the existing scheduling solution, replacing existing node.js & mongoDB solution with a golang & postgres based one. For this I developed a new bounded contexts structure, filtering what belongs and not to the scheduling domain.

For this I developed a new bounded contexts structure, filtering what belongs and not to the scheduling domain. This led to a simplicity of the scheduler and better debugging and recovery possibilities. New code was structured according to the Clean Architecture rules. This also let me present it to the other teams to compare with existing one to demonstrate it’s benefits. Also I changed scheduler api to an event based one which led to a great performance and stability. After this all load tests confirmed great performance of the service, when the old version never completed a half of it’s work. I introduced a better git usage strategy for the services, this simplified CI/CD and Release process. Continuously observed DB metrics and improved our queries. One added index reduced average load from 96% to avg 30% on a large aws instance. Which was less than in the idle time. Show less
