Case studies

Four real engagements. In each one I set out the context, what I did and, where there is one, the result.

Medicarama · 2024–2026

IT leadership and AI automation in a training SME

Context

From 2024 to 2026 I was Head of IT (Director de Sistemas) at Medicarama, an SME that provides online training for healthcare professionals. The work was organised by OKR: the objectives were to automate processes and to advance digital transformation towards AI; the key results were the hours of work saved and the number of AI agents with business functions.

What I did

I led a team of five. I set the area's priorities and led the automation of production, marketing, sales and customer service. On the projects I led, we put into operation AI agents for customer service, a sales assistant, and the classification of support tickets and the replies to them.

Result

20 hours of work a week were saved. The customer-service agents, the sales assistant and the classification of support tickets and the replies to them reduced queries to the helpdesk team by 60%.

Invoice Automator for accounting firms (export to a3asesor)

Invoice Automator screen: the invoice list, the fields read for review, the original invoice and export to A3.

Context

Since 2023 I have worked as an independent consultant (Mollatechlab). The Invoice Automator is a tailored, turnkey service for accounting firms and advisory practices that receive invoices as PDFs, by email or as photographs and have to post them to the accounts.

What I did

The solution collects the invoices (inbox, folder or drag and drop), uses AI to read the supplier or customer, NIF, number, date, taxable bases, VAT, withholding and total, checks balances, duplicates and invoices already posted, and lets the firm review and validate before exporting. It currently exports to a3asesor (A3 ECO) via its link file, and it can be adapted to other accounting programs. The AI reading is designed to run on a computer in the firm, without sending the invoices to the cloud.

Result

I am implementing the service with a first client, an accounting firm. The project is under way.

Tools

  • AI document reading
  • Export to a3asesor (A3 ECO)

I was responsible for incident management, with reporting to senior management, and for a catalogue of around 100 services covering requests, problems and change management (ITSM).

Context

Between 2013 and 2017 I was responsible for IT purchasing at Mercadona.

What I did

I took part in the evaluation and selection of IT products and services, in the negotiation of contracts and in supplier management, aligned with business needs and procurement policies. I was part of the supplier-management team and I worked on standardising purchasing in line with those policies.
