I will create a production ready postgres schema
About this Gig
Need a clean PostgreSQL database schema for your app or startup?
I will design a production-ready Postgres schema and deliver runnable, versioned SQL migration files with best practices: constraints, keys, and indexes so you can build safely and scale later.
What you get
- Clean database design (normalized where needed)
- ERD / schema diagram (for clarity)
- SQL migrations (.sql files) to create/update your schema
- Constraints: PK/FK, NOT NULL, UNIQUE, CHECK
- Indexes for common lookups, joins, and sorting
- For Standard/Premium: example SQL queries + Python/pandas connection example
What I need from you (to start)
- Short description of your app/use-case
- List of entities (tables) + key fields
- typical queries (e.g., list orders by user, search by email)
- Any special rules (unique fields, deletion rules, timestamps, etc.)
Important scope notes
- Many-to-many join tables count as tables.
- Revisions cover adjustments within the agreed scope (new entities/features require an upgrade).
- If your project is larger, Ill recommend the right package or a custom offer.
Message me before ordering if you're unsure Ill confirm the best package quickly.

FAQ
Do you only work with PostgreSQL?
Yes—this gig is focused on PostgreSQL. If you need MySQL/SQLite too, message me and I can confirm scope or create a custom offer.
What do you mean by “SQL migrations”?
You’ll receive runnable, versioned .sql files (e.g. 001_init.sql, 002_indexes.sql) that create/update the schema. No framework required.
Do you provide an ERD (schema diagram)?
Yes. I include an ERD to make tables and relationships clear. It helps you and your team implement faster and avoid mistakes.
Do you add indexes and constraints?
Yes. I add PK/FK constraints and practical UNIQUE/CHECK/NOT NULL rules. I also add baseline indexes for common lookups, joins, and sorting.
What counts as a “table” in your packages?
Each physical database table counts, including join tables (many-to-many). Views and extra reporting tables are add-ons.
Do you support Python/pandas integration?
Yes (Standard/Premium). I provide a short Python/pandas example to connect and read/write a table (SQLAlchemy). Full ETL pipelines are a separate service.
What do you need from me to start?
A short app description, list of entities + key fields, and 2–3 typical queries/use-cases. If you have an existing schema, share it and I’ll refine it.
