Experience

Senior Back-End Developer, Insurance Platform

April 2021 – April 2022

Description: Platform that provides full functionality for providing insurance in various areas: automotive, real estate, travel, property, health, investment, etc. The system is used by hundreds of thousands of people at the same time, so the issue of good performance and response time
is acute. Part of my job was to develop adapters that allowed the scaling and distribution of
responsibilities for different parts of the system. One adapter is a microservice that performs
the minimal task, and also collects metrics and sends traces to Grafana & Zipkin, respectively. This ensures effective monitoring of each part of the system and eliminates the possibility of a long downtime in case of failures. Soap requests to credit bureau API for verification, synthetic monitoring & testing.
