Noah Göktekin - Software Engineer

About Me

I'm a Software Engineer with 6+ years of experience. I started out building websites and web applications in agency and SME environments before moving into backend development on complex internal systems.

At KBB, I develop and maintain an internal business application for the Berlinale. In a small engineering team, my work spans Groovy and Grails, data modelling, workflows, access control, integrations, and production support.

I work across data models, permissions, and workflows so that changes fit the business process as a whole. With ImmoKlix, I also take a product from its user flow and calculation logic through payment integration to deployment.
