- Database-related issues (queries, performance, integration)
- Debugging production or staging environments
- Technical analysis and recommendations
My approach
I work carefully on existing systems, focusing on stability, clarity, and maintainability. I understand that legacy systems are often business-critical and must be handled with precision.
