About Jaime

Computer Engineer by training, profession, and vocation. As a child, I used to modify video games and extract their audio files. Strange, I know. But it was ideal to discover my passion for technology then, to enjoy it today as a profession.

On a technological level, I specialize in developing applications for Apple platforms: the technology that fascinates me.

However, I have a very full-stack past: Java, J2EE web applications, back-end, .Net (C#), APIs, SQL databases, Android apps... the truth is I've done it all.

I strive for my work to stand out for its quality, offering readable, documented code, organized by layers, that complies with architectural patterns and good programming practices. The result is software that, in addition to functioning correctly, is secure, error-resistant, and easily maintainable, which is appreciated when making any future evolution or correction.

I am based in Barcelona but usually work remotely, with periodic communication as frequently as the project requires, in Spanish or English (I am bilingual).

I ensure a healthy and friendly relationship with my client and their team. I believe that work should allow us to learn, exercise our creativity, and interact with interesting people to inspire us and bring us happiness.

We will be a good match if:
a. Easy communication and cordial treatment are important to you.
b. You are looking for an experienced developer whom you do not need to micro-manage.
c. You choose the cost of quality over the cost of non-quality.

I respect all professions, but I prefer to avoid projects that promote gambling or are contrary to my values.

I am available for part-time or full-time projects, eager to participate in an interesting cause. I would be delighted to talk to get to know each other and create an extraordinary digital product together.
