About

Junior software engineer with two years of experience building multi-tenant CRM solutions in Angular and Spring. With a dual background in Business Administration and Computer Science, I bridge domain knowledge—accounting and supply chain—with technical implementation. Most curious about system performance and simplifying complex data workflows.
