Lecturers

Luděk (programátor)
Luděk (programátor)

He is the programmer who most often takes care of the backend, creating an API for the frontend or mobile applications. Uses Java and PHP programming languages. It stores data in relational databases (MySQL) or other repositories (especially Elasticsearch, but also MongoDB or Redis). However, he is most interested in Elasticsearch. If it makes sense, it uses a microservice architecture and has more complex operations processed in the background via RabbitMQ.

He is interested in Linux containers, specifically Docker and Kubernetes tools. With their use, he has experience in local development and in the production environment. He is a supporter of the DevOps philosophy and uses CircleCI and GitLab CI for CI / CD.

He often participates in development conferences and meetings, where he draws on new knowledge, which he passes on in the form of articles, trainings and lectures (eg Last Saturday, where he talked about the aggregation of container logs using the Elastic Stack).
