I build private AI automation pipelines and reliable backend infrastructure for clients.
What I'm looking for
I deliver end-to-end AI automation systems for clients, from scoping requirements through production handoff. My focus is private, on-premise LLM integrations with Ollama and n8n, keeping sensitive data inside client infrastructure.
For a fintech client, I automated ingestion and processing of more than 100,000 banking transactions, combining n8n, PostgreSQL, Docker, SQL, and a locally hosted LLM to surface fraud and spending insights.
I also build production backend platforms in Java and Spring Boot, using TDD, Mockito, Liquibase, Docker-hosted PostgreSQL, and GitHub Actions to provide reproducible, maintainable delivery.
My infrastructure work includes high-availability web systems with Nginx, HAProxy, Linux VMs, AWS EC2, CloudWatch, JMeter, SSL termination, health checks, and load-balancing analysis. At Swisscom, I helped standardize development environments, roll out Okteto cloud environments, and troubleshoot deployment issues.
