AI Engineer at Defence Industry who built an on-prem LLM inference cluster and agentic tools for 90+ engineers.

At Defence Industry, I designed and built an on-prem LLM inference cluster and gateway in Kubernetes under defence-grade compliance standards. I also shipped an internal agentic coding harness, AI chat, and PR review bot used by the company’s 90+ engineers and specialists.

At Tripletex, I built agentic systems for a product used by 160,000+ Norwegian businesses, including a data analysis system that generates visualizations and insights from business data. I also built a multi-agent routing layer and customer support agents that resolved about 70% of requests without human support.
