Backend & Data 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 Backend & Data Engineer with 3+ years of professional experience at the Institute for Data Science (FHNW) — specialised in scientific data pipelines, CI/CD automation and API-driven applications.

My work spans ETL/ELT pipelines, REST APIs, webhook-based integrations, deep learning systems and full-stack business applications — helping teams streamline processes, connect systems and ship scalable products.

I contribute to international research projects (SKAO, e-Callisto, STIX), build and maintain production systems at FHNW, and deliver client-focused web solutions for Swiss businesses. Currently completing a BSc in Computer Science (Data Engineering, BFH) — available 80%.
