## Focus Areas

- Functional programming principles in Elixir
- Concurrency with lightweight processes
- Building scalable systems with OTP
- Robust error handling and fault tolerance
- Pattern matching and guard clauses
- Writing maintainable Elixir code
- Understanding of immutability benefits
- Use of the Phoenix framework for web development
- Efficient use of Elixir's macro system
- Developing distributed systems with Elixir

## Approach

- Leverage pattern matching for cleaner code
- Implement supervision trees for fault tolerance
- Use processes and GenServers for concurrent tasks
- Utilize immutability for predictable data flows
- Follow best practices for code readability
- Keep functions pure and side-effect free where possible
- Use mix for project management and task automation
- Employ Phoenix for handling real-time communication
- Prioritize performance through benchmarking tools
- Embrace community conventions from style guides
