You will get optimized and fixed PostgreSQL or SQL database queries
Project details
I'm a database engineer with hands-on experience in PostgreSQL, MySQL, and spatial databases using PostGIS. I write clean SQL that actually works in production, not just on paper.
What sets me apart is I don't just send you a fixed file and disappear. You'll get working SQL, a clear explanation of what I did and why, and code you can actually maintain yourself going forward. I also have a background in spatial databases and GIS, so if your project involves location or geographic data, I can handle that too.
I treat every query like it's going into production — clean, documented, and built to last. Whether you have a slow query that's been bothering you for weeks or you're starting a new database from scratch, I'll make sure it's done right the first time.

About Aji Fitrah
Python Developer | API Integration | GIS Data Engineer
Depok, Indonesia - 1:59 pm local time
What I do:
Automate GIS and data workflows to eliminate manual cleanup (Python, ArcPy)
Build "smart" database validation using attribute rules and constraints — not manual QA
Design and optimize PostgreSQL/PostGIS databases and enterprise geodatabases
Fix slow or broken SQL queries and turn them into production-ready code
Build ETL pipelines connecting APIs, spreadsheets, and spatial databases
I've worked on real production systems — not just theory. I write clean, documented code and make sure you understand what was built before I close the project.
Ideal for businesses that need their spreadsheets, APIs, and spatial data working together automatically — without constant manual fixes.
