What I'm looking for

I seek roles building production GenAI systems and MLOps pipelines in cloud-native, compliant environments, with opportunities to lead technical delivery and improve model governance.

I am an AI & GenAI Architect with 14+ years of experience in AI/ML development and UI/backend engineering, with early experience in .NET and extensive work in Java-based enterprise systems.

I design and deploy production-grade MLOps pipelines, optimize model inference and distributed workloads, and customize LLMs using LoRA/PEFT and fine-tuning to improve domain accuracy and reduce latency.

At UBS and Credit Suisse I led GenAI applications—building RAG systems, conversational data query assistants, and approval-scoring pipelines—integrating LangChain, LangGraph, Azure OpenAI, FastAPI, MLflow and enterprise search to deliver measurable performance and UX gains.

I value explainable, compliant AI and cloud-native architectures that scale; I focus on reducing deployment cycles, improving throughput and latency, and enabling self-service and data-driven workflows in financial enterprises.
