At Softgarden, I build LLM features for the recruitment platform, including an AI Screening Assistant that generates screening criteria from job offers and scores candidates. Its event-driven pipeline is now in rollout, scoring 1,000+ candidates a day.

I also built an LLM gateway with tracing and cost visibility, plus evals that gate prompt and model changes. I help engineering teams adopt AI-assisted development, and previously led full-stack development of MitElis at Berendsen (Elis Group).
