Backend & Integration Engineer · Bern, Switzerland

Hi, I'm

Delberin Ali

I build scalable APIs, system integrations and business applications — helping companies automate workflows, connect systems and launch reliable digital products.

About Me

Welcome to my portfolio. I’m Delberin Ali, a Software Engineer focused on backend development, system integration and API-driven applications. I build reliable digital solutions using Node.js, Python, .NET, PostgreSQL and modern web technologies.

My work includes REST APIs, webhook-based integrations, automation workflows and full-stack business applications — helping teams streamline processes, connect systems and launch scalable products.

Through freelance projects and my work at the Institute for Data Science (FHNW), I have contributed to production systems, backend services, deployment pipelines, data flows and client-focused web solutions for Swiss businesses.
