I've spent six years at SAP Labs building production software for SAP S/4HANA Cloud, including global trade compliance and public-sector workflow capabilities. My work spans Fiori applications, ABAP backend services, SAPUI5, CDS, RAP, IAM, and automated regression testing.

I build enterprise-grade agentic systems using OpenAI Agents SDK, LangChain, LangGraph, CrewAI, AutoGen, ChromaDB, and FastAPI. My projects include multi-agent research and financial-analysis pipelines, persistent AI assistants, decision-driven automation agents, and fine-tuned domain models.

My graduate research in adversarial ML robustness gives me an evaluation-first approach to AI reliability. I investigate failure modes, apply guardrails and validation at handoffs, and turn prototypes into scalable systems that ship.
