SignalsMaster

In Development

A specialized learning management system purpose-built for sea cadets where each unit operates in its own isolated digital space with complete data separation. Think D2L/Canvas, but for maritime training.

Overview

SignalsMaster is a specialized learning management system designed to modernize sea cadet training. Unlike generic LMS platforms, it is purpose-built for the maritime context, offering specific modules for Signal Flags, Seamanship, and Drill. The platform utilizes a multi-tenant architecture, ensuring that each cadet unit operates in a completely isolated environment—securely managing their own cadets, data, and progress tracking while benefiting from a shared, robust infrastructure. Starting with a pilot at Oakville Sea Cadets, it aims to scale to units nationwide.

Problem Domain

The Challenge: Fragmented & Inconsistent Training
  • •No centralized learning platform tailored to maritime cadet training.
  • •Fragmented knowledge management across drives, emails, and paper.
  • •Inconsistent training delivery across different units.
  • •No way to track cadet progress or mastery of critical skills.
  • •Limited engagement—training feels like homework rather than achievement.
  • •Legacy Ionic app had limitations—need for modern stack for better UX and maintainability.

Our Solution

Our Solution: Dedicated Multi-Tenant Platform
  • •Modern Stack Migration: Re-building from Ionic to Next.js + ShadCN for better performance.
  • •Multi-Tenant Architecture: Each unit sees only their cadets, quizzes, and leaderboards.
  • •Specialized Learning Modules: Signal Flags, Points of Sail, Drill, Seamanship.
  • •Gamified Assessments: Quizzes with instant feedback, achievements, and unit leaderboards.
  • •Data Isolation & Security: Complete separation of unit data with row-level security.
  • •Offline Capability: PWA with offline mode for field training scenarios.

Multi-Tenant Architecture

Isolated Digital Spaces
  • Unit: Oakville Sea Cadets (Pilot) - Cadets, Officers, Modules, Data
  • Unit: Future Units - Same structure, completely isolated data
  • Platform Level: Shared infrastructure, expansion ready
