Understand the data
Exploratory analysis, statistics and predictive models. Understand the problem first; choose the model second.
PEOPLE, DATA AND SYSTEMSDATA SCIENCE / AI ENGINEERING
01 / MEET CARLOS

Classical history has fascinated me since childhood. How did Rome organize an empire without modern telecommunications? Part of the answer lay in information: harvests, resources and reports that helped people understand the present and anticipate problems. That curiosity about how we make decisions became the thread running through my career.
At Cofidis, I worked in data analysis, demand forecasting and project management. I learned that a good solution starts with understanding the business and needs more than technology: clear goals and teams that understand each other. My Scrum training reinforces that approach.
That journey led me to deepen my knowledge of data science, Python and machine learning through studies at UOC and Tokio School. Today, at MELMACIA LAB, I work on data preparation and analysis, pipeline automation, and model training and validation.
I’m now extending that perspective to AI engineering and building applications based on foundation models. My interests include prompt engineering, RAG systems and connecting data, models and interfaces to turn their capabilities into useful tools that can be evaluated.
That is where I position myself as a Full-Stack AI Engineer: at the intersection of data, business and building solutions. The tools change, but the question remains: how can we turn what we know into better decisions?
Exploratory analysis, statistics and predictive models. Understand the problem first; choose the model second.
Python, data preparation and pipelines. In my portfolio, I explore APIs, document retrieval and local generative AI.
Requirements, KPIs and project coordination. My Scrum training supports a team-centered approach to work.
Data collection and preparation, pipelines, exploratory analysis, model training and validation, and hyperparameter tuning.
Data science and Python internship.
Requirements analysis, service quality, process improvements and testing of new developments.
Project definition, team coordination, KPI monitoring and project management in Spanish and French.
Exploratory and statistical analysis, demand models, dashboards and training on analytical tools.
02 / ENGINEERING IN PRACTICE
Academic projects and a new applied engineering laboratory. Code, methodology and limitations in the open.
What can we discover by looking at several variables together?
An app for exploring their relationships, finding similar profiles and trying prediction models.
What happens to a fleet as vehicles move, break down and return to service? Change the conditions and watch it evolve.
An app for comparing actual bike rental demand with a model's estimates, and exploring its predictions under different weather conditions.
When does a temperature change deserve attention? Explore a signal, review its alerts and introduce changes to compare two ways of detecting anomalies.
My final Big Data project: an air traffic analysis bringing together data preparation, exploration and the presentation of findings.
