You will get a clean database schema and ERD diagram for your app
Project details
Does your app or software project need a solid database foundation?
I will design a clean, professional relational database schema tailored to your specific project. You will receive a full ERD diagram showing all tables, relationships, primary keys, foreign keys, and constraints, plus SQL-ready scripts and documentation your team can use immediately.
I work as a data engineer at a bank building production databases daily. Every schema I deliver is designed to scale, not just to work today.
This project is ideal for developers building a new app, founders validating an MVP, or students who need a professional database design delivered fast.
Message me before purchasing and I will tell you exactly what I can build for your project.

Database Designer and ETL Pipeline Developer | Data Engineer
Santiago, Chile - 1:24 pm local time
I help startups and small businesses design clean database schemas, automate data pipelines, and build dashboards that make sense of their data.
I work as a data engineer at a bank in Chile, building production pipelines that process thousands of records daily. I bring that same level of precision to every freelance project I take on.
What I can build for you:
Relational database schemas and ERD diagrams for your app
Python ETL pipelines that move and transform your data automatically
Looker Studio dashboards connected to your data sources
Custom web apps with React and Supabase
Airtable databases to replace your messy spreadsheets
Message me and tell me what you need. I will tell you honestly if I can help.
