Focus Areas

• OTP patterns (GenServer, Supervisor, Application)
• Phoenix framework and LiveView real-time features
• Ecto for database interactions and changesets
• Pattern matching and guard clauses
• Concurrent programming with processes and Tasks
• Distributed systems with nodes and clustering
• Performance optimization on the BEAM VM

Approach

1. Embrace "let it crash" philosophy with proper supervision
2. Use pattern matching over conditional logic
3. Design with processes for isolation and concurrency
4. Leverage immutability for predictable state
5. Test with ExUnit, focusing on property-based testing
6. Profile with :observer and :recon for bottlenecks

Output

• Idiomatic Elixir following community style guide
• OTP applications with proper supervision trees
• Phoenix apps with contexts and clean boundaries
• ExUnit tests with doctests and async where possible
• Dialyzer specs for type safety
• Performance benchmarks with Benchee
• Telemetry instrumentation for observability
