ACTIVE DEVELOPMENT
MatrixOS
A secure interactive IT and Computer Science portfolio designed as both a professional recruiting platform and an evolving technical learning project.
- TypeScript
- React
- TanStack Start
- TanStack Router
- Tailwind CSS
- PostgreSQL
- Row Level Security
- TOTP MFA
- Zod
PROBLEM
Traditional portfolios often show technologies without demonstrating how they are applied or how security and access control are designed.
GOAL
Build a portfolio that combines professional presentation, technical documentation, interactive features, and security-by-design principles.
IMPLEMENTATION
Current implemented features: - Matrix-inspired responsive interface - Recruiter Mode - Public portfolio sections - Secure administrator console - Private administrator authentication - TOTP multi-factor authentication - AAL2 enforcement for administrative access - Database-backed administrator authorization - Row Level Security (RLS) - Public read views with restricted column exposure - Draft / published content workflow - Certification and skill management - Contact-channel management - Private media storage architecture - Audit logging - Secure CMS architecture PLANNED (not implemented): - Matrix Lab simulators (PLANNED) - AI Recruiter Assistant (PLANNED)
SECURITY CONSIDERATIONS
MatrixOS uses defense-in-depth rather than relying only on frontend route protection. Administrative access is protected through authentication, MFA/AAL2, database-backed roles, Row Level Security, restricted grants, and server-side validation.
LESSONS LEARNED
Practical application of secure application architecture, authentication, authorization, database access control, content management, and full-stack development concepts.
