About Julio.Works
Mission
The quality of software shouldn’t depend on how big the client is, how much they can spend or where they operate. Julio.Works exists so that any individual or company, wherever they are based, has access to software worthy of their project.
Today I design, build and maintain websites and applications for individuals and companies in Spain and abroad.
It all began in 2011, protecting servers against attacks designed to take them offline, and over time I specialised in developing applications and websites. From 2016 I worked with a consultancy on international development projects in several African countries, and from 2019 to 2021 I led technology at one of the largest online health and beauty retailers in Spain.
In 2021 I brought that experience together under the Julio.Works brand, to offer every client the same standard of rigour whatever the size of the engagement. Alongside development, I integrate artificial intelligence into companies’ day-to-day operations and manage their infrastructure.

Working principles
Every project is approached in the same way, regardless of its size or scope
- Analysis
The problem comes first
I analyse your processes before choosing the technology, and the proposal justifies every choice in writing.
- Architecture
Designed for the real environment
Each system is designed for the connectivity, the workload and the security requirements of the place where it will run.
- Artificial intelligence
AI with a measurable purpose
I integrate artificial intelligence where it saves time or improves a decision, with an objective defined before work begins.
- Security
Confidential by default
Every project is treated as confidential, with a signed agreement if you need one, and your data is hosted in the European Union unless you prefer another location.
- Ownership
Everything in your name
The code, the data and the documentation are yours, and they are prepared so that any team can take them forward.
- Direct relationship
One person in charge
The person who listens to you at the first meeting is the one who designs, builds and maintains your project.
Let’s start shaping your project
Tell me what you have in mind or what you need built, and I’ll reply within 48 hours with a detailed assessment and a realistic scope.
