About this Gig
A database designed in a hurry costs you twice: in bugs now, and in rework when you want reports or AI on top of it. I design your data model so it holds up, or review the one you have.
What you get
- An entity relationship diagram (ERD) your team can read
- Tables, keys, relations and data types, normalised where it matters
- From Standard: a ready-to-run SQL script (DDL) and a data dictionary for every field
- Premium: an analytics layer, history tracking and a readiness check for AI and reporting
- Works for a new design or a review of your existing schema
How it works
1. You describe what the system must store, or send your current schema
2. I confirm scope and price before you order
3. You receive the ERD, the documentation and, from Standard, the SQL script

FAQ
Which databases do you design for?
PostgreSQL, MySQL, SQL Server, SQLite and Supabase. Airtable and similar tools on request. Tell me what you use or plan to use.
Can you review my existing database instead?
Yes. Send the schema export (SQL DDL) or an ERD. You receive the issues, their impact and the fixes, in the same package sizes.
Do you need access to my data?
No. The design works from your requirements or your schema alone. No production data is needed.
What does ready for analytics and AI mean?
Clear keys and relations, consistent types, a documented meaning for each field, history that is kept, and personal data that can be separated. Reports and AI projects rely on exactly that.
Will you build the database for me?
From Standard you get an SQL script your developer can run. Building the application or migrating data can be a separate custom offer.
Where are you based, and how is my data handled?
I work from Germany, under EU data protection law (GDPR). Your files are used only for your order and deleted after delivery. NDA on request. If data must stay in the EU, tell me before you order.
