Hello! My name is Vladislav Trotsenko. I'm software engineer from 🇺🇦 Ukraine, currrently located in Poland, Kraków. I'm backend developer who inspired by Ruby, Go, Crystal and scalable microservice architecture. I've been actively working on Open Source Software for over 3 years, while having a full-time job at the same time.

My serious Open Source journey began in 2019 when I have released first version of truemail - configurable framework agnostic plain Ruby email validator/verifier. Very quickly this project increase the popularity and grew into a whole family named as truemail-rb. Currently you can use truemail inside your Ruby or Golang codebase natively or as independent microservice, available as docker image also. For today truemail server has 3 native clients for Ruby, Crystal and Java. All truemail family codebase is well documentated and available at: https://truemail-rb.org

During working on truemail gem I have faced with lack of tools for doing integration tests. This has prompted me to create mocktools organization with first repo - Ruby DNS mock. Later I have released Go & Ruby SMTP mocks under mocktools namespace.

Maintenance and contributing to these projects need huge effort, requires attention and time. I appreciate your support!
