What I'm looking for

I’m looking for an AI product role where I can own 0-to-1 delivery, define LLM/RAG pipelines, enforce output quality, and iterate with adoption metrics—preferably in B2B SaaS with strong cross-functional collaboration.

I’m an AI Product Manager and former Backend Engineer with 8+ years delivering AI signal extraction products and B2B SaaS platforms. My work centers on defining LLM/RAG pipeline requirements, setting AI output quality standards, and shipping usable AI for expert teams in real time.

At Obsevia, I co-founded the company and served as first PM, building an ECHA regulation chatbot that extracted actionable signal from unstructured EU chemical regulations for compliance managers. I defined the requirements for an LLM/RAG pipeline, launched three AI products from 0 to launch in 7 months without a prior PM playbook, and won a EUR 10,000 AI Nation Grant.

Before that, at Verimi, I owned a GDPR-compliant, Gematik-regulated Wallet-as-a-Service SDK and SaaS API platform serving 10M+ users. I defined KPI metrics using Prometheus and Grafana, governed the roadmap with Jira and Confluence, and delivered meaningful gains in reporting efficiency and user trust metrics.

My backend engineering foundation (Python, PostgreSQL, Java, Kafka, SQL) helps me make system-level product decisions with technical credibility. I also bring a data-driven approach—from dashboarding in PowerBI/Metabase to using field feedback loops to iterate from day one.
