I’m César, a computer scientist, software engineer, and content creator.

I’m passionate about science, software technology, and teaching.

Here is my minimalistic resumé.

Update: Since April 2023, I’m a Data Engineer at SEB in Stockholm :sweden:.


I’d a PhD in Computer Science in the Department of Software and Computer Systems at KTH Royal Institute of Technology. My research was supervised by Benoit Baudry and Martin Monperrus. I graduated in 2023.1

My PhD was about software debloating,2 here’s my thesis and public defense.

Besides my PhD topic, I do knowledge-seeking software engineering research. For example, by extracting useful information from data stored in software repositories.3 I’m particularly interested in measuring the impact and pervasiveness of software bloat across large-scale software ecosystems.

I’m keen to perform research on software technology which:

  1. Provide actionable insights to researchers and practitioners about how modern software is currently being developed and maintained.
  2. Produce practical tools for developers to improve software quality.
  3. Disrupt the status quo of software engineering latest practices.

I’m always open to work with researchers and supervise students in these areas. If you are interested in collaborating with me, have a look at my list of research topics.


I also hold a BSc and MSc in Computer Science.

A long time ago, I participated in programming competitions.


Out of work, I enjoy spending time with my family, reading physical books, and jogging across the Stockholm’s beautiful parks.4
