Production projects

Federated GraphQL API Gateway Hybrid Cosmo (WunderGraph) Splitting the Go router (runtime query execution) from the TypeScript Controlplane (schema registry and management) lets Cosmo scale and deploy the performance-critical data path independently, while a dedicated ClickHouse-backed metrics service keeps high-volume usage analytics off the primary Postgres database.
Error Tracking Platform Classic Sentry Pairing Django with Kafka and ClickHouse allows Sentry to ingest billions of events daily while providing sub-second analytical search across production traces.
LLM Observability AI-agent Langfuse Storage is split by workload: Postgres via Prisma for relational app state, ClickHouse for high-volume trace analytics, and Redis-backed BullMQ for async jobs, while a separate Rust Axum service handles latency-sensitive LLM proxying outside the Node runtime.
Privacy Web Analytics Classic Plausible Analytics Pairing the BEAM virtual machine with ClickHouse allows Plausible to ingest high-volume telemetry surges reliably with minimal RAM and fast analytical queries.
Product Analytics Platform Hybrid PostHog Pairing Apache Kafka with ClickHouse columnar storage enables PostHog to ingest billions of monthly events while maintaining sub-second query response times.
Secret Management Hybrid Infisical Audit logs are split into ClickHouse for analytical-scale queries, key-management and HSM/PKCS11 operations run in a separate Go service backed by Redis task queues, and dynamic-secret rotation for Oracle and SAP ASE ships with vendored native drivers baked into the backend image.
Job Queue / Dev Tool Hybrid Trigger.dev Trigger.dev eliminates serverless timeout restrictions and queue boilerplate by providing durable, resumable TypeScript workflows.
Content Platform Classic Ghost Ghost runs its core server, a React admin app that is replacing a legacy Ember admin in place, and every public-facing widget as separately Vite-built packages inside one pnpm/Nx monorepo, so the publishing surface, the editor and each embeddable script can evolve and ship on their own schedule.
CRM SaaS Hybrid Twenty Twenty provides an extensible, modern CRM architecture featuring metadata-driven custom objects, GraphQL APIs, and clean UI design.
Web Analytics Hybrid Umami Umami provides cookie-free, GDPR-compliant website metrics and session replays with simple self-hosting and zero data monetization.
