About this Gig
Your app needs a clean PostgreSQL database, but the schema is messy, queries are slow, or you are starting from zero and need it done right.
That is the work I do. I am Kawsar, a Python developer who designs PostgreSQL databases, writes SQL queries, and tunes performance so your data layer stays clear and fast.
What I deliver:
- PostgreSQL schema design with relationships and ERD
- SQL scripts for tables, constraints, and sample data
- Complex queries, views, and functions when you need them
- Index and query tuning notes for slow paths
- Optional Python connection sample on Premium so your app talks to Postgres cleanly
I work on new database design, SQL query writing, and PostgreSQL optimization for apps, APIs, and data projects. Stack: PostgreSQL, SQL, pgAdmin, Python when needed.
Message me your requirements or current schema before you order.
NOTE:
- You provide access details or schema notes securely in order chat
- Custom work per order
- No school or university assignments

FAQ
What do you need from me to start?
A short brief of entities and relationships, or your current schema dump / ERD. Message me before ordering so we match the right package.
Will I get SQL files and an ERD?
Yes. You get schema scripts and an ERD-style diagram. Sample data is included on Basic and above as scoped.
Can you write complex queries and functions?
Yes. Standard and Premium cover joins, views, and functions when your requirements need them.
Do you install servers or set up replication?
Full DBA install, clustering, and streaming replication are custom offers. Message me if that is your main need.
Do you include Python with the database work?
Premium includes a small Python sample to connect and run a query. Deeper API work can use my Python API gig.
Is this for school or university homework?
No. I do not take school or university assignments.
How do you handle database access?
Prefer schema files or a staging DB. Share credentials only inside Fiverr order chat. Never send production passwords in public messages.
