Engineer working in IT since 2018. I started in technical support and today I design integrations and automate processes across enterprise systems — mainly in the Jira, SAP and AWS ecosystems. I have worked in both small and large organizations, on Windows and Linux.

I build end-to-end solutions that combine software, integration and AI: .NET, ABAP, Groovy, JavaScript and SQL, plus integration and automation tooling. I put strong emphasis on technical documentation (Confluence). I use large language models daily (ChatGPT, Gemini in the cloud; Ollama locally), matching the tool to requirements, security and context.
