Hi, I'm Nik 👋

Senior Applied AI Engineer building production AI systems end-to-end, from problem framing and data pipelines to evaluation, inference, and deployment.

I bring 10+ years of engineering experience across SaaS, logistics, e-commerce, and AI-native products, and as an ex-Founder I combine technical depth with strong ownership and the ability to turn ambiguous problems into reliable systems used in production.

My work sits at the intersection of AI systems, backend engineering, and product ownership: agent orchestration, RAG and retrieval, fine-tuning and evaluation workflows, and high-throughput inference for data-intensive and financial use cases.
