Featured Snippet

Clean Code Standards

I believe code should be self-documenting. Whether it's Python, PHP, or JavaScript, I adhere to strict standards (PSR-12, PEP 8) to ensure that the systems I build are maintainable by your team long after I leave.

✓ Type Hinting & Static Analysis
✓ Comprehensive Error Handling
✓ Modular, Testable Components
