timothy.fehr@fehrcoding.ch · fehrcoding.ch · German, English

Profile

Software architect and senior backend engineer with more than 10 years of experience building and running production backend systems in enterprise settings (banking, insurance, telco). My focus is Java / Spring Boot, software architecture (iSAQB Advanced), cloud-native platforms (AWS), CI/CD and infrastructure as code.

In complex organisations I like to take technical responsibility, bring structure to unclear requirements, and care about sustainable system architecture, well-founded technical decisions and stable platforms.
