Ivan Kulagin

My name is Ivan, and I am a backend developer since 2012. Since then I selected the stack of different lovely technologies I use daily in my work: Ruby language, TypeScript/Javascript, testing, refactoring, microservices, devops, data parsing/manipulation, APIs design, and of course trendy AI & Automation workflow building (which is actually no/less-code backend development).
