You will get SQL query fixes and database reports
Project details
Do you have an SQL query that does not work, returns the wrong results, or needs to be created for a database report?
I can help you write, fix, review, and improve SQL queries for reports, data extraction, summaries, filters, joins, and business analysis.
I work with PostgreSQL, MySQL, SQLite, and SQL Server. I can help with SELECT queries, JOINs, WHERE filters, GROUP BY summaries, aggregations, date conditions, subqueries, CTEs, and report-ready outputs.
This project is best for clients who need clear SQL logic, query debugging, database reports, or help turning database tables into useful results.
Please note: this service does not include server administration, database recovery, full database migrations, advanced performance tuning, scraping, full ETL pipelines, or dashboard development. You do not need to share passwords or sensitive credentials.

About Pedro Danilo
Data Analyst | Python, SQL, Power BI | Data Cleaning & Automation
Plato, Colombia - 2:45 am local time
I help organizations, consultants, researchers, NGOs, small businesses, and academic teams transform messy or unstructured data into clean datasets, reports, dashboards, databases, and actionable insights.
I can help you with:
• Data cleaning and transformation in Excel, CSV, and databases.
• SQL queries and reports in PostgreSQL and MySQL.
• Python scripts for automation and ETL workflows.
• Power BI dashboards and data visualization.
• Data extraction, data mining, and analytical reporting.
• Geospatial data analysis with PostGIS and GeoPandas.
• Technical reports based on structured data.
My background combines more than 25 years of experience in public administration, institutional consulting, project management, and data-driven decision-making with technical skills in Python, SQL, PostgreSQL, PostGIS, GeoPandas, Power BI, pandas, and machine learning.
One of my key projects involved designing a PostgreSQL/PostGIS data repository with more than 128 million socioeconomic and violence-related records from Colombia, including Python ETL processes, source traceability, and municipal geolocation.
I work remotely by project, with clear scope, defined deliverables, structured communication, and practical results.
