Database design affects far more than where information is stored. A carefully planned data model can make applications easier to scale, integrate, maintain, and adapt as requirements change. The companies below provide database design as part of custom software development, backend engineering, data services, and broader product development projects.
1. Gilzor
Gilzor develops custom software products with database engineering built into the wider application architecture. Its technology stack includes MySQL, PostgreSQL, MongoDB, and Amazon S3, alongside backend technologies such as Node.js, Python, FastAPI, Django, SQLAlchemy, and TypeScript. This combination is useful for projects where database structure needs to work closely with APIs, business logic, cloud infrastructure, and user-facing applications.
The company works across web and mobile development, business analysis, QA, and DevOps. Database planning can therefore remain connected to the complete product rather than being handled separately from application development. Gilzor also works on existing products that need architectural changes, performance improvements, or modernization.

Conclusion
Database design services can cover very different needs, from creating a schema for a new application to restructuring data within an established enterprise system. The right technical approach depends on the type and volume of data, expected growth, application architecture, integrations, security requirements, and the technologies already in use.
These companies approach database work from different angles. Some combine it with full-cycle product engineering, while others bring enterprise development, cloud, fintech, mobile, or extended-team experience. Comparing their database technologies and surrounding engineering capabilities can help businesses narrow the field according to the actual requirements of the project.
