horizOn · Backend and developer platform
MY ROLEProject lead, product owner, software architect and lead developer
As project lead, product owner, software architect and lead developer, I am responsible for the concept, development and operation of horizOn, a backend-as-a-service platform for games and digital products.
The current platform is based on Kotlin and Spring Boot. An earlier generation was developed using ASP.NET Core, .NET 8 and Entity Framework.
An Angular dashboard, APIs, real-time communication and custom engine SDKs connect the backend and developer tools. Authentication and multi-tenancy are part of the platform architecture. A custom MCP server, distributed as an npm package, makes horizOn accessible directly from AI coding tools. PostgreSQL and Hibernate/JPA were used in an early product phase before data storage moved to MongoDB.
Load and security testing accompany ongoing technical development.
Result: Built a backend platform with a dashboard and engine SDKs, and implemented development, testing, release and operational workflows for multiple regions.
