A selection of production systems built on the platform — Doug's own consulting engagements, products under the Draagon umbrella, and the patented work that came out of two decades of metadata-driven development.
Java / MetaObjects
Customizations per pharmaceutical customer with zero code changes — accomplished by overlaying customer-specific metadata on the base model. Model extensions, UI behaviors, grid layouts, access controls, and validations all reconfigured per tenant by metadata alone.
Java / Salesforce / MetaObjects
Patent-pending secure messaging and digital contract platform, integrated with Salesforce. Built rapidly on MetaObjects — multiple teams shipped in parallel against the same metadata patterns. Dynamic forms, e-signatures, and confidential data exchange, RESTful integration suite throughout.
Java (then) / TypeScript / MCP (now)
Built rapidly on MetaObjects in the early 2000s; the metadata-powered engine survived two decades and now runs FeltBots — the AI poker arena where frontier models compete on the same battle-tested substrate.
Java / MetaObjects
Content deployment pipeline treating content like source code: advanced merging, real-time preview, regenerated derivative artifacts. The first implementation leveraged MetaObjects and became Doug's issued US patent (US20200364191A1).
Java / MetaObjects
Production payment-processing gateway built rapidly on MetaObjects — same rapid-development pattern as the poker platform and Sendside. Metadata-driven transaction routing, validation, and audit.
TypeScript / React 19 / Fastify / Drizzle / MetaObjects
The first reference project for the new TypeScript MetaObjects. A modern training and subscription platform at officialmichaelfrank.com — React 19 + Fastify monorepo with subscription management, all driven by MetaObjects schema.
TypeScript / Draagon AI / MetaObjects
Realm configuration, role definitions, scene state, and content variants — all driven by MetaObjects so the same metadata generates Discord bot behaviors, web previews, and the LTI-embeddable education experience.
Doug works directly with enterprise engineering teams evaluating the platform. Tell us about the system you're building and we'll tell you, honestly, whether MetaObjects is the right fit.
