I will design and optimize your sql or postgresql database
Where others see problems, I build solutions
I’m Ali Hassan, a .NET Core 8/9 developer with 8+ years of experience in AI automation, API integration, and PDF/label generation. I build fast, secure, and scalable systems using C#, Dapper, EF Core,...
About this Gig
I'll design, normalize, and optimize your SQL Server or PostgreSQL database ready for integration with any backend such as ASP.NET Core, Node.js, or Python. With 9+ years of experience in database architecture, I focus on data integrity, indexing, scalability, and clean relationships to ensure your system runs fast and stays reliable.
What you'll get:
- Logical & physical database design (ERD diagrams)
- Normalized schema (1NF to 3NF)
- Primary/foreign keys, relationships, and constraints
- Indexing for performance optimization
- Stored procedures, views, or functions (on demand)
- Export scripts (.sql) + documentation

FAQ
What databases do you work with?
I work with SQL Server, PostgreSQL, and MySQL. For enterprise solutions, I can also support Oracle on request.
Can you integrate the database with my app?
Yes! I can provide the integration layer for ASP.NET Core APIs, or export connection-ready scripts for your team.
Will I get the database diagram (ERD)?
Absolutely. You’ll receive a visual ERD (PDF or image) showing all entities, relationships, and keys.
Can you optimize an existing database?
Yes, I can review your schema, suggest normalization, create indexes, and tune queries for faster performance.
Can you design both relational and NoSQL databases?
Yes! My main focus is on relational databases (SQL Server, PostgreSQL, MySQL), but I can also help you design or refactor NoSQL structures like MongoDB if your project requires flexibility or document storage.
Do you also handle database migration from one system to another?
Absolutely. I can help you migrate your existing database from SQL Server → PostgreSQL (or vice versa) while preserving data integrity, constraints, and relationships.
Will you include test/sample data in the design?
Yes, for the Premium package, I include sample test data for each table so you can easily test your queries and application integration.
How will you deliver the final files?
You’ll receive a complete SQL script, ERD diagram, and documentation (table descriptions, keys, and relationships). I can also share a .bak or .dump file for instant restore if needed.
What if I don’t know how many tables I need?
No problem! Just describe your system or send me a rough outline (like “users, orders, products”), and I’ll plan the right structure and suggest the number of tables for you.
Can you secure my database against SQL injection or misuse?
Yes. I design schemas that enforce referential integrity and parameterized query standards, reducing risks of injection and data corruption.
