Open-source Firebase alternative with Postgres backend. Experienced in building pluggable storage architectures with automatic schema generation and lifecycle management.
Technical Deep Dive
Core Concepts I'm Proficient In:
• Postgres Integration: First-class Supabase Client with full PostgreSQL database access for structured data storage
• Schema Management: Implementing automatic table creation and schema generation for zero-config deployment
• Authentication Service: Experience with Supabase Auth for secure user authentication (solid features with some limitations)
• Storage Service: Leveraging Supabase Storage for reliable file storage and retrieval operations
• Row-Level Security: Implementing access policies and security rules ensuring appropriate users have correct permissions
• Client Development: Building custom Supabase clients for framework integration (BMAuth Supabase client)
Advanced Supabase Implementation Patterns:
• Pluggable Storage Architecture: Designing storage backends that work with Supabase while supporting fallback options
• Lifecycle Management: Managing complex data lifecycles for users, sessions, challenges, and verification flows
• Debug Endpoints: Building observability tools that expose internal state for development and troubleshooting
• Security Configuration: Implementing row-level security policies early in development to ensure proper permissions
• Zero-Config Deployment: Creating systems that work out-of-the-box with in-memory storage, then seamlessly upgrade to Supabase
• Database Reliability: Building systems that monitor and maintain database uptime without service interruptions
Complex Problem-Solving Examples:
BMAuth Supabase Storage Backend:
Developed a comprehensive Supabase/Postgres storage backend for the BMAuth authentication framework that handles the complete authentication lifecycle. Built automatic schema generation that creates necessary tables (users, challenges, sessions, verification_codes) on first connection, enabling zero-config deployment where the system self-initializes its database structure. Implemented lifecycle management for WebAuthn credentials, authentication challenges, active sessions, and recovery verification codes, ensuring proper data retention and cleanup. Created debug endpoints that provide observability into authentication state during development, helping developers troubleshoot registration and login flows. The storage backend includes intelligent fallbacks - if Supabase isn't configured, the system seamlessly uses in-memory storage for development and testing.
Security and Permissions Architecture:
Implemented row-level security policies in Supabase early in the BMAuth development process to ensure users can only access their own authentication data. Configured security rules that prevent users from viewing other accounts' credentials, reading other users' sessions, or accessing verification codes not intended for them. Tested both Supabase Auth (found it solid but with limitations for advanced use cases) and Supabase Storage (reliable for file retrieval operations). Built the Supabase client integration to be straightforward - the client creation process proved manageable, allowing BMAuth to offer Supabase as a production-ready storage option alongside in-memory development mode.
Areas for Continued Growth:
• Advanced Authentication: Exploring Supabase Auth's full capabilities for building sophisticated authentication systems
• Real-Time Features: Learning Supabase Realtime for building live collaborative features and real-time data synchronization
• Edge Functions: Mastering Supabase Edge Functions for serverless backend logic close to users
• Database Reliability: Deepening expertise in monitoring, alerting, and ensuring zero-downtime database operations at scale
