I’m a full-spectrum software engineer from Switzerland specializing in modernization and cloud migration, delivering 10x productivity through pattern recognition and systematic execution.
I architect complete technical solutions across the entire stack. Recent Swiss Post engagement: migrated their online waybill application from Spring Boot 2.4/Angular 8/Oracle on-premises to Spring Boot 2.7/Angular 18/PostgreSQL on AWS/Kubernetes, implemented FedEx APIs, added 5,000+ tests, and established CI/CD with ArgoCD. Management described it as “setting the bar for excellence” and uses it as reference material.
Core Capabilities:
Backend (Java/Spring Boot, Elixir/Phoenix, PL/SQL, Rust, C#), Cloud/Infrastructure (AWS, Kubernetes, Nomad, Terraform, Linux/RHEL), Frontend (ReactJS, Svelte, VueJS, Angular), Test Automation (Robot Framework, Jest, Playwright, Selenium), DevOps (Jenkins, GitHub Actions, Docker, CI/CD pipelines).
What Differentiates Me:
E-shaped professional with deep expertise across multiple domains and strong execution capability. I connect business requirements, technical constraints, and operational realities into cohesive solutions—leading complex migrations, establishing testing frameworks, optimizing databases, and handling infrastructure without coordination overhead.
Sector Experience: Financial Services (PostFinance, Migros Bank, Zürcher Kantonalbank, Sanitas), Logistics & Public Sector (Swiss Post).
Current Focus: Distributed systems (Elixir/Phoenix), AI integration, infrastructure optimization. Recent certifications: ISTQB Foundation, LLM/MCP, Terraform.
I work through my Swiss LLC for optimal flexibility. Best suited for complex modernization projects requiring full-spectrum execution.
