About this Gig
A slow app is usually a database problem. Missing indexes, a schema that grew by accident, queries that scan the whole table.
I design and optimize databases for startups, SaaS products and web apps MySQL, PostgreSQL, MongoDB and SQL Server.
What I do:
- Query optimization: find the slow queries, rewrite them, add the right indexes
- Schema design: normalized structure with clear relations, built around how your app reads data
- Restructuring and migration: fix an existing database or move it without losing data
- Cloud setup on AWS RDS and MongoDB Atlas
- ERD and documentation, so your team can work without me
How it works:
1. Send your schema, a slow query, or a description of the problem
2. I tell you what I would change and what it costs, before you order
3. I make the changes and show you the timings before and after
4. You get the scripts, the diagram and notes on what changed
Not included: application code changes, server administration, ongoing monitoring.
Message me with your slow query or your schema and I will tell you what is wrong with it.

FAQ
Can you work on my live database without breaking anything?
I work on a copy or a backup first, test the changes there, and only apply them to your live database once you have seen the results and approved them.
What do you need from me to start?
A schema dump or database access, two or three queries that feel slow, and a short description of what the application does. If you are starting from scratch, just describe the data you need to store.
Will this make my whole app faster?
I can show measured before-and-after timings on the queries we target. Overall app speed also depends on your application code, hosting and traffic, so I will tell you honestly if the bottleneck is somewhere other than the database.
Can you migrate between databases, for example MySQL to PostgreSQL or SQL to MongoDB?
Yes. Migrations are scoped separately because the work depends on data volume and how different the two structures are. Send me the details and I will quote it.
