I started at the very bottom — office helpdesk, then hosting technical support — and grew into an engineer who owns production infrastructure. Several years in outsourcing gave me dozens of client projects of every size: audits, migrations, CI/CD pipelines, observability, incident response.
Today I develop an information security platform and lead a team of five engineers. My approach hasn’t changed since the support desk: find out why it broke, then fix it so it stays fixed. Certified in Yandex Cloud.
Working principle: keep it simple. Complexity can always be added later — it is far harder to remove. If a task is solved by one server and a script, I will say so rather than sell a cluster.
