Alex Chernov

I am an experienced Software Engineer and Technical Leader with over a decade of expertise in building and scaling applications, primarily with Ruby on Rails. Since 2010, I have contributed to more than a dozen Rails-based projects, covering diverse domains such as travel, adtech, fintech, logistics, legal, CRM, and DevOps.

My professional focus lies in software architecture, systems thinking, and entrepreneurship, combining deep technical knowledge with strong leadership and strategic vision. I have held positions ranging from Software Engineer to Tech Lead, Application Architect, and Deputy CDO, consistently driving results by optimizing systems, improving processes, and fostering high-performing teams.

I adapt quickly to changing environments and strive to make the greatest impact in every role. My technical expertise is complemented by strong soft skills, enabling clear communication and effective collaboration with teams, stakeholders, and executives.
