Acerca de Jose
I help businesses stop guessing and start knowing.
What I do
- Build automated dashboards that show what's really driving profit
- Clean, organize, and centralize messy data (duplicate records, spreadsheets, broken tracking)
- Design data pipelines and reporting systems for decision-making based on facts, not intuition
- Build machine learning models when they actually add value — not just for show
Background
Former mechanical engineer turned data engineer. I understand how to translate business problems into data solutions. I write clean Python and SQL. I build systems that work reliably.
Why work with me
- I start by understanding the problem you're having, what you're trying to make, and then build exactly what's needed, nothing more
- I explain things without jargon — you'll understand your own data
- I deliver on time, or let you know early if something's off
Ideal projects
- Revenue/profitability dashboards and automated reporting
- Data cleaning, database setup, and pipeline automation
- Machine learning models for forecasting, classification, or optimization
- Manufacturing/operations analytics, internal business analysis (sales, ops, finance)
- I focus on data infrastructure first — because models are only as good as the data behind them.
I won't promise to "10x your revenue with AI." But I will build solutions that work, save time, and help you make smarter decisions.
Let's talk if your data is costing you time or money.
