01 — About
Systems, automation, integrations.
I’m a self-taught enterprise IT and integration specialist with 15+ years of hands-on experience across applications, automation, EDI, web development, and systems operations.
Experienced across the Microsoft and Azure ecosystem, with hands-on Linux, web-stack, database, and automation work. I focus on automation, observability, and reproducible operations — I treat environments like code, logs like truth, and outages like puzzles.
I apply AI and digitalization where they deliver measurable operational value: agentic workflows, MCP servers, and LLM-assisted development connected to the business applications, ERPs, and data platforms teams already depend on.
Automation
Manual routines turned into repeatable pipelines that run unattended and leave an audit trail.
Operations
Applications that stay available, with incidents diagnosed and resolved before they escalate.
AI Engineering
Internal systems made reachable by AI agents, so support and delivery work moves faster.
