Are your SQL queries running painfully slow, or do you need a clean, scalable database schema for your new project?


As a dedicated database and backend specialist, I help you design, structure, and optimize your relational databases for peak performance.


What I can do for you:

  • Design clean, normalized database schemas (ER diagrams / SQL scripts)
  • Write, debug, and optimize complex SQL queries, joins, and subqueries
  • Create indexes and performance tweaks to speed up slow queries
  • Set up tables, relationships (1:1, 1:N, M:N), and constraints


Why work with me?

  • Clean, efficient, and well-commented SQL code
  • Fast turnaround times and clear communication
  • Focus on scalability and security best practices
