Barcik
R&D Engineer | DevOps Specialist | IT/OT Architect
I solve problems where industrial systems meet modern IT — connecting things that weren't designed to work together.
01. About
R&D and DevOps Engineer specializing in the convergence of IT and OT environments. I prototype innovative solutions in laboratory settings and scale them to production. I leverage programming strictly as a tool for advanced automation and industrial systems integration, optimizing core business processes through modern IT deployments.
