🗄️ Database Management

Structuring your data efficiently and securely, from small tables to complex systems.

A well-designed database is essential for speed, security, and maintainability. I work with:

• SQL (PostgreSQL, MySQL) – relational data, foreign keys, joins, transactions
• NoSQL (MongoDB, Firebase Firestore) – flexible schema, real-time updates
• Database modeling and schema optimization
• Indexing, caching (e.g. Redis), and query performance improvements
• Data migration from old systems or CSV files
• Backup and disaster recovery setups
