About me

Innovative, task-driven professional senior developer with 8+ years of experience in development across diverse industries.

I am currently working with a research team learning new technologies and tools for big data processing. I have experience in creating, developing, and integrating microservices for complex projects. I use NodeRED to develop visual workflows and employ Python for asynchronous scraping to efficiently collect and process data. Python is also useful for creating and building an environment for running ETL jobs in Airflow. Thanks to PostgreSQL I can provide data storage and retrieval, and my expertise in Linux enables you to optimize system performance and ensure reliability. Rancher helps me to manage containers and orchestrate services.

In addition to my technical expertise, I am also highly proficient in documenting my work. I create detailed documentation with Swagger for each microservice I develop, which enables other developers to understand the functionality and purpose of each service.

In the last year, I´ve had an opportunity to be part of the certification program - Rest API, Math problems, and Design Patterns which I successfully passed.
