Does any of this sound familiar?
If your business is dealing with any of these situations, I can help you solve it.
Your team loses hours to manual work in Excel
Monthly reporting, data cleaning, copying and pasting between sheets... I automate those workflows so they run on their own, without errors.
You make decisions without reliable data
I design clear dashboards with the KPIs that really matter. Up-to-date, accessible, actionable data for your management team.
You want to use AI but have no technical team
I implement machine-learning solutions tailored to your business: sales forecasting, customer classification, anomaly detection.
Everything depends on one person
If “the data person” goes on holiday, nobody knows how to produce the report. I document every solution and train your team so you depend on nobody, not even me.
Services
Tailored solutions for every stage of your data project: from strategy to implementation and training your team.

- Data modelling and DAX measures
- Executive and operational dashboards

Automated Reporting
Periodic reporting that generates and distributes itself: reports per client, branch or week, exported to Excel or PDF in the exact format the recipient needs.
- Paginated reports (Report Builder / SSRS)

Diagnostic
I review your current situation, data sources, tools and challenges. Together we identify the highest-impact opportunities.
Proposal
I design a tailored solution with clear scope, timeline and deliverables. No surprises, no small print.
Delivery
Iterative development with weekly check-ins. Documented, reproducible, production-ready code.
Handover
Technical documentation, team training and post-delivery support. Your team becomes self-sufficient.

Results from real projects
A few examples of what I have delivered across different sectors.
Serverless applications on AWS
Internal serverless applications on the AWS ecosystem for an international logistics operation, alongside dashboards, data analytics and automated day-to-day reporting.
Fraud detection with machine learning
A machine-learning model to identify fraud patterns, with dashboards to explore the cases detected and prioritise the business team’s work.
IoT dashboards in European projects
Participation in European research projects: Power BI dashboards for IoT sensor data and scientific data analysis shared with the consortium partners.
Energy invoice automation
Automatic invoice processing with Python and consumption-data analysis for energy-efficiency projects. From an invoice file to analysis-ready data.
ETL and academic Business Intelligence
Work on the database: source mapping, ETL pipelines, Power BI dashboards and automations for academic management.
Automated reports per client
Weekly reports generated automatically per client (activity, cost per km, kilometres) with an Excel export ready to send. Configurable rolling windows of weeks.
Laboratory, chemicals or pharma? We speak the same language
I am a chemist by training, with laboratory experience, and I have contributed to scientific publications. If your company is a laboratory or works in the chemical or pharmaceutical sector, I understand your data and your processes from the inside: analytics, traceability and automation with the rigour the sector demands.
Why a freelancer rather than a consultancy?
Results, not slide decks
Every line of code solves a real problem. I do not sell slides full of promises; I deliver working solutions.
Direct contact, no intermediaries
You talk to me from the diagnostic to the delivery. No sales reps, no staff turnover, no lost context.
Your team stays self-sufficient
I do not create dependency. I document everything, train your team and deliver clean code. After the project, you are self-sufficient.
Pricing that fits a small business
No big-consultancy overhead. Fixed prices, no hidden hours. You pay for results, not for corporate structure.
See how I work
I share what I know in the open: videos, technical articles and public code (mostly in Spanish). The best way to evaluate someone you are about to hire is to look at their work.
Code on GitHub
Public repositories with clean, documented, reproducible code. This is how I deliver my projects.
Technical articles
I write about data, automation and good practice, based on real problems from real projects.
Videos and courses
Free Python and data-analysis courses. If I can explain it, I have mastered it.
Calculator
How much is that manual task costing you?
Pick a repetitive task (the weekly report, keying invoices into Excel, consolidating spreadsheets…) and move the sliders. The result is instant, no sign-up.
1 = monthly · 4 = weekly · 20 = every working day
Include checking, fixing and sending. It is usually more than it seems.
Cost to the company, not net salary. An admin role is around €18–25; a manager, €40–60.
