KION
Senior pythI managed a development team in one of the departments of the online cinema kion.ru. I also developed and implemented libraries, tools, and practices that enabled the team to focus on solving business tasks and streamline microservices development. This, in turn, reduced TTM and enhanced the reliability of services. Responsibilities: • Development team management (stand-ups, grooming, planning, interviews, 1-1 meetings). • Tech leadership (strategic planning, backlog and technical debt management, code review, technology selection, architecture design, mentoring). • Development of the key parts of the system (development-to-management time ratio was about 50%). • Documentation: descriptions of processes and development standards, technical documentation, architectural diagrams. • Standardisation of development processes and tools. • Ensuring non-functional requirements compliance, monitoring and alerting systems configuration. Achievements: • Established standardised development practices and integrated tools such as linters, formatters, and code analysers into the development process and CI pipelines. • Introduced project templating, significantly reducing the time required to create new microservices. • Developed tools for working with internal infrastructure, allowing for faster feature development. • Proposed and implemented the Sentry monitoring system, enabling rapid errordetection and correction. • Implemented a project build pipeline integrated with the release system in Gitlab. • Initiated the use of MongoDB in the project, providing an optimal solution for specific data storage and processing challenges.on developer
