Sobre mí
I'm a database engineer. I fix broken queries, speed up slow ones, and build database structures that actually make sense. I work mainly with PostgreSQL and MySQL. If your queries are taking forever, your schema is a mess, or you need scripts written from scratch — that's my everyday work. I also have a background in spatial databases and GIS, so if your project involves maps or location data, I can handle that side too. I don't overcomplicate things. You tell me what you need, I build it, and I make sure you understand what I delivered before I close the order.... Lee más

I take on database projects independently — mostly fixing databases that have gotten messy over time or building new ones from scratch. I write and optimize PostgreSQL queries, design normalized schemas, and create migration scripts when a client needs their database restructured. I also do PostGIS work for clients dealing with location or geographic data.

I work with spatial data and geographic databases on a daily basis. Most of my time goes into building and maintaining geodatabases in ArcGIS Pro, writing attribute rules to automate data validation, and making sure the spatial data stays clean and consistent. I also handle the database side — writing SQL queries, managing schemas, and keeping everything running properly on the backend.
