Freelancer profile translated to English.

Description

I am a FullStack Engineer. I have extensive experience in developing and integrating microservices and big data solutions. I use AWS, GCP, or bare metal infrastructure stacks.

My skills include DevOps knowledge with tools like Kubernetes/Terraform/Earthfile/Ansible, which allows me to quickly set up POCs.

On the SQL database side, I have in-depth experience with PostgreSQL and MySQL. For NoSQL databases, I use HBase and ElasticSearch.

My favorite language is Scala. I am a proponent of functional programming. I also master Python.
