Participating in all aspects of software development at a rapidly growing startup. Main focuses on backend development and architecture, test automation and building a reliable, redundant infrastructure that's transparent in a way that enables all support tiers to quickly solve customers' issues. My daily work revolves around things like MongoDB, ElasticSearch, Logstash, Redis, MemSQL, RabbitMQ, Ansible, PHP and Python. As its second employee I have witnessed Smartly.io's growth from having zero revenue to being a profitable business with 90+ of employees, and what a ride that has been! The pace is not about to slow down anytime soon, and we're constantly hiring more smart people with a GSD attitude. Join us! http://smartly.io/careers

I worked as a quality-oriented software engineer in a backend development team. We created and maintained mainly Python-based systems for handling file (malware) and URL reputations automatically, and provided data mining and other tools for analysts. My tasks ranged all the way from test automation and test/deployment infra maintenance to fixing bugs, architecture planning, development and, in general, dealing with all kinds of issues typical to complex systems. Tools, technologies, concepts and methods I used daily included Python, JSON, REST, Scrum, Git, TDD, Cassandra, RabbitMQ etc.
