About me

Looking for a job

I'm a software engineer experienced in people and project management. In my last workplace, I've introduced a lot of people management practices. I have very flexible technical skills: I can reach a minimum needed technology understanding in a short time.

Hey, I'm Sergei Riabinin, a Team Lead and Web Developer for a bit less than 10 years.

My professional interests

... to become better with a company I'm working for. Now I'm focusing on Development management: hiring, firing developers. I can help with rescue from burnout, or take control over low performance. I can look into processes and help to improve them.

As a list: people management; people growth assistance; task distribution; architecture expertise; project management; process building.

My personal interests

... to be a good father, husband and to build up a really comfortable smart home for my family. With that aim I have some experiments with 3D printing, and a lot more.

Familiar with the following technologies:

DevOps: Docker; nginx; traefik; Docker compose; GitLab CI/CD; Jenkins; Bash.
Backend: Node.js/Bun as a choice, Java, .NET as required; Apache Kafka, Redis, RabbitMQ and gRPC for cross-system communication.
Frontend: Vue/React.js for advanced use cases - with Nuxt/next meta-frameworks, TypeScript usage preferred.
Used in the past: Java EE 8, PHP 5 (Yii 2.x).
