I'm currently working on the Backend of Cloud Platform project to provide Business-to-Business (B2B), Business-to-Consumer (B2C), Business-to-Government (B2G), and internal teams the ability to order cloud services based on Platform as a Service (PaaS) and Infrastructure as a Service (IaaS) models.Link to the company: https://sbercloud.ru/enMy responsibilities included:* Build and provide development processes inside team (including code-review approaches, unit/integration testing etc)* Code review* Mentoring team members and conducted one-to-ones. * Conducting interviews and onboarded newcomers* Maintenance and development of microservices (30+ microservices).* Participation in the development and architectural planning * Search and implementation of new technologies.* Finding and eliminating the causes of failures of applications and microservices on production environment.Tech stack: Go, PostgreSQL, Kafka, Redis, S3, GitLab CI/CD, Docker, Kubernetes, temporal, PythonProjects: - feature stand (separate stand) for each branch approach (with single based kafka)- implement code review and unit tests practice inside team (which wasn't present before me)- introduce generic approach to microservices skeleton, which increase development speed- billing module (from scratch) consisting of several microservices, which allows us to build more cloud native architecture
