Profile

Professional profile

I have been programming on a self-taught basis since the age of 12. At 18, right after completing my university entrance exams, I began my professional career when I joined Triskel in June 2024. Since then I have moved from a development-focused role to also taking on analysis and the technical definition of projects, and I currently work as a Software Developer & Analyst. I value both hands-on experience and a solid academic education, which is why in September 2024 I started the Computer Engineering degree at the UOC online: it allows me to combine my studies with my job, strengthen the fundamentals and gain a broad view of everything the field encompasses. I complement it with specific training in programming, databases and systems.

  • Passion since 12, profession since 18

    Self-taught programming since age 12 and professional experience since 18.

  • Work and studies

    I combine my role at Triskel with my degree at the UOC.

  • Continuous learning

    13 complementary courses (900 hours) since 2024.

Software Developer & Analyst

Triskel · 10/06/2024 – present

I joined Triskel in a development-focused role. Over time I have taken on greater autonomy and responsibility: analysing requirements, assessing alternatives, planning projects and contributing to their technical definition. I currently carry out development and analysis tasks typical of a software engineering role.

My experience spans several layers of a solution: backend systems and web services, web development, native Android applications, and firmware for geolocation devices. I have also worked with databases, integrations using various communication protocols and incident resolution, and I have been involved in projects end to end: analysis, implementation, testing, support and further development.

I have contributed to nationwide livestock slurry management solutions, projects in the biogas sector and developments for public bodies and emergency services, including Mossos d'Esquadra, Bombers and Agents Rurals. Through incident resolution I have dealt directly with clients and users, which has strengthened my communication skills and technical judgement.

    Assess alternatives and define the technical approach before implementation.

  3. Implementation and testing

    Develop in the relevant layer (backend, web, Android or firmware) and verify that it works.

  4. Support and evolution

    Resolve incidents and ensure the solution remains maintainable in the long term.
