Patient-data platform for European hospital networks; HIPAA + GDPR.

• Led the re-architecture of the records ingestion pipeline from REST polling to a Kafka-based event stream, processing 12k events/sec at peak and reducing data freshness from 5 min to under 8 sec.
• Designed and shipped a regional data-residency layer that lets each hospital network choose where its data lives — unblocked three enterprise deals worth €4.2M ARR.
• Mentored four engineers from mid to senior; two became tech leads within 18 months.
• Owned the 24/7 on-call rotation; cut sev-1 incidents 60% YoY by adding synthetic monitoring and a load-shedding circuit breaker.

Product analytics SaaS, ~$30M ARR at exit.

• Built the real-time funnel-analysis query engine on top of ClickHouse, dropping median dashboard load from 8s to 600ms.

• Drove adoption of an internal RFC process — 28 RFCs in the first year, halving rework on cross-team initiatives.

Logistics SaaS for Scandinavian retailers.
