Software Engineer at The Original Body AG

January 1, 2026 - May 31, 2026

Ported a Palantir Foundry filter app into a Twenty CRM fork as part of a CRM stack migration, replacing Close.io, Funnelbox, and a large portion of Palantir Foundry with a self-hosted open-source stack (Twenty CRM, Listmonk, n8n, Twilio, WAHA). Designed and shipped the data layer for Lead Cockpit v2.0 using NestJS, React 18, Apollo/GraphQL, PostgreSQL 16, and TypeORM. Built a hybrid query architecture combining Twenty's native GraphQL with custom NestJS resolvers for cross-table JOINs, GROUP BY counts, and live AND-intersection cohort counting. Implemented bidirectional sync between Twenty and Listmonk, including Listmonk setup, full contact migration, continuous + daily-backup sync, and unsubscribe propagation back to the source CRM. Reverse-engineered the legacy Foundry app into a merge-ready scope spec and orchestrated translation from spec to single-task Codex prompts with explicit scope fences and done conditions.
