Achievements:- Improved performance and quality of CI\CD processes. Providing improvements to Azure DevOps pipelines and making the CI\CD process more flexible and efficient. Making single deployment of various solutions hosting in different OS into the same development environment. Up to 30% improvement to CI\CD pipelines in different time.- Providing GitOps culture with code reuse that allows saving time during writing new pipelines, makes Dev\Stage\Prod environments as similar as possible, and disallows accidentally untracked changes to come into the working environment.- Optimize spending costs for non-efficient usage of Azure services by analyzing the load of running services. As a result, some services were scaled down and others were disabled or removed. - Optimize spending costs for non-efficient deployment to Kubernetes scenario. By providing flexible resource definitions that could be configured during the deployment for each solution.- Create integration of Kubernetes monitoring with Azure portal. Implement collecting metrics from different sources, provide persistent storage for them, and build a single alerting system that observes different platforms.Using: Kubernetes · Helm Charts · Istio · Grafana · Prometheus · Kibana · Microsoft Azure · Microservices · Azure DevOps · Powershell · Docker · Azure Kusto · YAML · Grunt

Achievements: - Optimized code performance for the usage of Redis Servers that allows scale down from 8 shards to 2 and decreasing hardware requirements. As a result, it saves an impressive number of money and leaves space for future scaling.- Other performance and memory improvements that allow optimizing of business scenarios. And improving test routines and processes. One of them shows on LT framework request execution time improvement from 30% to 200% on different test scenarios. Others are not so significant.- Owning the development of global features, improvements, and POC. Consolidating the work in other teams. Like migration from obsoleted Microsoft LoadTest solution written on C# to Locust written on Python, or POC for implementing .net Bencmark in one of the solutions.- As Scrum Master improved team involvement during the retrospective meeting with practice to switch a host each sprint. Involved in the decision to lock the time frame for daily standups and decrease the waste of time. Improvement on running the Demo meeting making it more time efficient by splitting it into technical and product parts, where the last part is optional for Devs and QA's and recorded.- As Scrum Master introduced areas of responsibility that reduced time spent on code reviews and finding experts in particular areas.
