DOJO APP

The Vision

Traditional Goju-Ryu martial arts relies on a complex, hierarchical syllabus that is often managed through paper logs and manual tracking. I built the Dojo App to modernize this process—creating a digital mirror of a physical practice. It is a full-stack forms management system that handles the rigorous progression from 10th Kyu (White Belt) to 8th Dan (Black Belt).

Three Engineering Decisions That Mattered

Syllabus Engine — translating 48+ traditional forms (Kata, Bunkai, Kumite) into a rigid data schema was the hardest part. The requirements system prevents curriculum inconsistencies: practitioners only see forms relevant to their rank and lineage.

Soft-Delete — accidental data loss in a training environment is demoralizing. A dedicated Trash interface allows immediate correction while maintaining a permanent audit trail without cluttering the active database.

Multi-Tenant Isolation — owner-scoped queries and MongoDB indexing ensure every practitioner's data is completely isolated, protected by JWT authentication and bcrypt hashing.

Technical Deep Dive

As an instructor of Okinawan Goju-Ryu, I built this to solve a real problem in my own field — not to code an app.
