What I build

Built and shipped a production SaaS turning Denmark's public company register into valuation, ownership and market data, working as an engineer across the stack.

• Designed the LLM pipeline that parses free-text Danish legal filings into validated capital-history chains: every raise, reduction, merger and demerger, cross-checked against structured register data.
• Built the valuation engine, an ownership graph resolving ultimate control across holding structures, a market-comparables matrix, and a feed poller maintaining millions of rows.
• Shipped the full commercial layer: Auth0, Stripe billing with a webhook-synced mirror, transactional email, Sentry-correlated audit logging over 1.2M rows, and a HubSpot lead-gen integration.
• Owned infrastructure end to end: Dockerised multi-service deploy on Fly.io (backend, frontend, Postgres, Redis), CI/CD and scheduled GitHub Actions pipelines running the data-refresh jobs and standing health checks that alert on silent pipeline degradation, with Sentry observability across the stack.
• Optimised production Postgres with partial indexes and query-plan analysis, cutting multi-second scans to sub-millisecond.
