You will get Build Accurate Machine Learning Models for Your Business
Top Rated
Project details
I design and implement custom Machine Learning solutions that transform raw data into actionable insights and measurable business impact. Whether you need predictive models, customer segmentation, anomaly detection, or advanced forecasting, I build reliable systems tailored to your goals.
My approach combines strong foundations in mathematics and statistics with hands-on expertise in Python, R, SQL, TensorFlow, and scikit-learn. I prioritize scalability, clarity, and business relevance: every model is documented, validated, and explained so you can trust and use the results.
With Machine Learning, you can: Anticipate trends and customer behavior, Automate decision-making processes, Optimize pricing, marketing, and operations, Detect risks and anomalies before they cause losses.
By working together, you’ll receive not just technical models, but clear insights and tools that directly support data-driven decisions and business growth.

My work focuses on understanding business problems, designing practical solutions and implementing systems that improve visibility, planning, efficiency and decision-making.
I believe technology should serve the decision, not the other way around.
Over the years I have worked across data engineering, analytics, forecasting, optimisation, machine learning and software development. Rather than treating these as separate disciplines, I use them as tools that can be combined depending on the context and objectives of each project.
I typically work on projects involving:
• Decision support systems and business intelligence solutions.
• Data architecture, databases and analytical infrastructure.
• Forecasting and scenario analysis for planning and operations.
• Optimisation and resource allocation problems.
• Process automation and operational efficiency.
• Machine learning and AI applications when they create measurable business value.
• Custom analytical tools that help teams understand, evaluate and act with greater confidence.
My approach is strongly business-oriented.
Before discussing technology, I try to understand the context, constraints and decisions that actually matter. The goal is not to build the most sophisticated system possible, but the simplest solution capable of creating meaningful and lasting value.
I enjoy working closely with clients, challenging assumptions, exploring alternatives and translating complex situations into clear, actionable decisions.
I work fluently in English, Spanish and Catalan and have experience collaborating with international teams across analytical, technical and operational environments.
If you are looking for someone who combines analytical rigour, technical capability and a genuine interest in understanding your business, I would be happy to discuss your project.
