I took part in designing and implemented prepaid and postpaid payment systems that are currently in large-scale production use by several large Mobile telecommunication operators in several countries.

I integrated Message Manager on two large mobile telecommunication operators.

My experience in both DBSS (python-based) and BSSAPI (scala-based) helped a lot in solving communication gaps between them.

I implemented a k8s cluster monitor and recommender that improves the quality of service for mission-critical applications.
