Hi, I'm Ernesto 👋

Computer Engineering Student @ UCLM · Ciudad Real, Spain 🇪🇸

Passionate about the intersection of Data Science, Statistical Inference, and AI.
Currently building a rock-solid theoretical foundation while getting my hands dirty with real-world data — from raw sensor noise to actionable insight.

What I'm focusing on right now

  • The Full Data Pipeline — I enjoy the grind of cleaning messy data, performing EDA, and drawing conclusions through statistical inference
  • Industrial Time Series — Analyzing patterns, detecting anomalies, and forecasting in real industrial environments
  • Statistical Rigor — Using hypothesis testing, regression, and mathematical reasoning to build honest, reproducible analyses

Tech Stack

Languages

Python R SQL Java

Libraries & Tools

Featured Projects

Industrial Sensor Digital Twin

Anomaly detection and predictive modeling on real industrial sensor data

Two end-to-end analyses on public industrial datasets — one for a solar generation plant, one for a water treatment facility.

Solar Plant Water Treatment Plant
Goal Identify underperforming inverters & estimate post-repair ROI Build a Digital Twin for 3 critical sensors during scheduled panel replacement
Key techniques IQR outlier removal, time interpolation, inverter performance ranking, Random Forest regressor Isolation Forest (multivariate anomaly detection), lag hypothesis testing, Linear Regression vs. Random Forest pipeline
Highlight Estimated yearly revenue recovery per faulty inverter repaired 76% of DQO-S predictions within 10% error margin using Random Forest

The Real Cost of University Grades

Full-scale statistical study on student habits and academic performance — designed, collected, and analyzed from scratch

A team research project where we surveyed 100 university students and put 4 popular myths to the test.

Hypotheses tested (with t-tests, α = 0.05):

  1. Students perceive themselves as more stressed than the scale midpoint (confirmed, p = 0.007)
  2. High-performing students sleep less (not confirmed — they actually sleep slightly more)
  3. Top students don't do sports (not confirmed — sport habits are nearly identical across grade groups)
  4. Students who study more consume more stimulant drinks (not confirmed)

Best regression model: grade ~ study_hours + sleep_hours → R² adj = 0.25
