Top SchoolMarcin Bajer is a Senior Back End Software Engineer with 16 years of experience building large-scale web applications and SaaS platforms, currently contributing to workforce optimization systems at ProFinda. He combines deep expertise in Ruby (especially Ruby on Rails), PostgreSQL and SQL with a strong Linux sysadmin background, enabling him to own both application logic and production infrastructure. Marcin has a long track record of remote collaboration across the US, Poland and Germany and routinely architects high-performance backends, background-processing pipelines and payment/reporting integrations. His toolset ranges from Redis, MongoDB and Nginx to deployment automation with Capistrano and Chef, reflecting a pragmatic focus on reliability and scalability. Unusually for a backend specialist, he also toggles into front-end JavaScript work when projects demand it, and he draws on decades of database-first thinking dating back to Visual FoxPro and Oracle systems. Based near Krak贸w, he pairs continued PhD-level study with hands-on delivery across startups and enterprise clients.
