Umut Yerebakmaz
Software Architect and Consultant
Summary
I have been writing software since 1992. Over that time I have worked across many sectors and technologies, from web agencies and e-commerce to embedded systems and enterprise software, and I actively support the open source ecosystem.
Today my focus is GIS-based enterprise software, high-performance APIs and complex data queries. I have advanced experience with Angular, PostgreSQL, GraphQL and TypeScript. I take an active part in business analysis and software architecture planning, and I build scalable, robust solutions that meet both technical and business needs.
