I will design and optimize mongodb and postgresql database
About this Gig
Is your database slow, poorly structured, or falling apart as your app grows?
I design clean, scalable database schemas and optimize existing ones, for MongoDB and PostgreSQL, so your app runs faster and your data stays reliable as you scale.
WHAT I OFFER:
- Database schema design from scratch
- Query optimization and indexing
- Slow query diagnosis and fixes
- Database migration (SQL to NoSQL or vice versa)
- Data modeling for MERN or Next.js apps
- Normalization and relationship design (PostgreSQL)
- Aggregation pipeline optimization (MongoDB)
- Backup and scaling strategy
TECH STACK:
MongoDB,PostgreSQL, Mongoose, Prisma, Node.js, Express
WHY WORK WITH ME:
As a full-stack developer, I design databases the way they'll actually be queried in production, not just on paper, so performance issues get caught before they cost you.
WHO THIS IS FOR:
Developers with a slow or messy database, startups scaling past their first few thousand users, and teams migrating between MongoDB and PostgreSQL.
BEFORE YOU ORDER:
Message me with your current schema (or app idea) and the specific problems you're facing, so I can scope this accurately.
Lets make your database fast and reliable.

FAQ
Do you need access to my existing database?
Yes, for optimization work I'll need read access (or a copy/dump) of your current database to diagnose issues accurately. For new designs, I just need your app's requirements.
Can you migrate my data from MySQL/MongoDB to PostgreSQL (or vice versa)?
Yes, migration between database types is supported, especially in the Premium package. Message me with your current setup and data volume for an accurate quote.
How do you diagnose slow queries?
I analyze query execution plans (EXPLAIN in PostgreSQL, explain() in MongoDB), review indexing, and check schema design for structural issues causing slowdowns.
Will you write the queries/code, or just design the schema?
Both — I design the schema and can also write or refactor the queries, ORM models (Mongoose/Prisma), and indexes needed to make it perform well.
What if my project has more than 10 tables/collections?
The Premium package covers unlimited tables/collections. If Basic or Standard scope needs to expand, we can adjust with a custom offer.
Do you provide documentation after the work is done?
Yes, all packages include documentation covering the schema structure and any changes made, so your team can maintain it going forward.
