Senior Data Engineer / Data Architect

Senior data architect and data engineering with 15+ years of experience designing source-of-truth data platforms, semantic data models, and operational analytics solutions across insurance, finance, and pharma.

Strong background in analytics strategy, data product platforms, metadata-driven automation, event-driven analytics, and cross-functional collaboration between business and engineering teams.

I specialize in turning complex business processes into governed analytical platforms that improve metric consistency, operational visibility, and decision support.

Professional Experience

Tryg — Senior Data Engineer

Oct 2023 – Present

Revenue Intelligence & Operational Analytics

  • Developed a revenue intelligence platform enabling standardized business metrics including NDR, GRR, Logo Retention, and funnel analytics across domains.
  • Built an event-driven analytical model enabling drill-down from executive KPIs to individual business events and operational decision points.
  • Established reusable semantic definitions and time-series business events to improve metric consistency, explainability, and cross-functional trust in analytics.
  • Enabled analysts and business stakeholders to trace revenue movements and customer lifecycle changes through sequenced business activities rather than isolated snapshots.
  • Created a foundation for future context-aware analytics and richer operational intelligence capabilities.

Data Product Platform & Strategy

  • Helped shape a data product strategy focused on reducing fragmentation, improving interoperability, and enabling scalable analytics delivery.
  • Built a shared data product platform improving consistency, reuse, and delivery speed across analytical domains.
  • Replaced fragmented self-service patterns with reusable governed building blocks and shared semantic concepts aligned with ACORD and domain-driven design principles.
  • Replaced dbt with SQLMesh to improve scalability, maintainability, and developer workflow for analytical data products.
  • Introduced isolated virtual development environments reducing dependency conflicts and improving collaboration across teams.

Metadata-Driven Automation

  • Designed a metadata-driven model generation approach turning declarative YAML definitions into governed SQLMesh models.
  • Automated generation of analytical building blocks including hook, bridge, and event models from reusable metadata, reducing manual SQL development and improving structural consistency across domains.
  • Modeled temporal validity, dependency-aware bridge logic, and reusable business keys as metadata instead of hand-coded model patterns.
  • Used dependency graphs and topological ordering to generate analytical structures in the correct sequence, improving repeatability and reducing delivery risk.

Lundbeck — Senior Data Architect

Sep 2021 – Sep 2023

  • Defined a common data layer strategy reducing fragmentation and improving interoperability across analytics and operational domains.
  • Replaced a monolithic data lake approach with a flexible platform inspired by Data Mesh principles.
  • Enabled scalable self-service analytics while maintaining governance and semantic consistency.
  • Collaborated across technical and business domains to align analytical capabilities with organizational needs.
