I am a Linux system engineer with 20+ years of experience. I know Linux from the inside out, so I am able to squeeze maximal performance out of it and unleash the full power of Unix. The latter is not just a better performance, but also an ability to perform complex tasks a simple way, which is one of the Unix principles. I specialize in designing and maintaining infrastructure for services that have to handle serious load, and this has led me to the fascinating world of cloud computing with its dynamic scalability and resources on demand. I am an expert in using all known DevOps tools for provisioning, orchestration, CI/CD, and Microservices ecosystems. I am very experienced in database optimization and administration: MySQL, PostgreSQL and MongoDB, including cluster management, replication and sharding. I have basic programming skills in Ruby, Python, PHP and Javascript. Which mean that I can at least read and fix the code :) I am expert in shell scripting. Very experienced in email and deliverability. Security expert (although there is always things to learn in this field). Good in troubleshooting and analyzing problems from multiple viewpoints. Easy to communicate with, with good sense of humor.
