Hello, I am Matias, researcher on AI-based software engineering at the Universitat Politecnica de Catalunya (Barcelona, Spain).

Current Interests and News:

• Automated Software Development & Testing

– I have developed tools and approaches to automate the development, evolution, and maintenance of software systems, with a strong focus on data-driven and AI-based approaches. Target tasks include Fault Localisation, Bug and Issue Repair/Fixing, Software Migration and Code Translation.

• AI and Machine Learning:

– Recently surveyed Agent-based approaches for issue resolving from SWE-Bench ArXiv draft version.

– Special interests on Large Language Models (LLM) for code tasks, specially on those that are open-source. For instance, recently published work on Sustainability of LLMs for code repair ACM TOSEM 2025.

– Research record on AI-based Software Engineering and Software Testing. Check my Google Scolar profile.

– Latest Hackathon Projects: During 2024, I participated in HACKBCN AI edition where our project won the award “Best developer solution” and in AINAHACK where I developed a solution using BSC’s Salamandra LLMs.

• Transferring Knowledge and Technology to Practice:

  – Interested in automating the development and maintenance processes in your company? Let’s talk Email.

• About teaching:

  – I am a teacher in a Master course on MLOps at the Universitat Politecnica de Catalunya (Barcelona, Spain). I teach how to build, test and deploy AI-based systems.
