Acerca de este Servicio
Is your app or software project stuck because you don't have a solid database foundation? A poorly designed database causes slow queries, data inconsistencies, and expensive fixes down the road.
I am a data engineer working in the banking industry with hands-on experience designing relational databases for real production systems. I will design a clean, scalable database schema tailored to your specific project needs.
What you will receive:
- Relational database schema designed from scratch
- Full ERD diagram showing all tables and relationships
- Primary keys, foreign keys, and constraints properly set up
- Naming conventions and documentation included
- PostgreSQL or MySQL ready scripts
This service is ideal for developers building a new app, founders validating an MVP, or students who need a professional database design delivered fast.
Message me before ordering and I will tell you exactly what I can build for your project.
