• Delta-update mechanisms with rollback, version detection, and audit trails
• IEC 62304-aligned packaging integrated into GitHub Actions CI/CD

🤖 AI Agent Development

• Build and deploy AI agents using LangGraph, MCP, or LangChain
• RAG pipelines against instrument manuals and support knowledge bases
• AI tooling (code gen, PR bots, test scaffolding) to accelerate the team

💻 Full Stack Application Dev
