My full name is César Soto Valero. I’m passionated about 1) software technology, 2) research, and 3) sharing what I know. I’m currently working as a Data Engineer at SEB in Stockholm, Sweden :sweden:.


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. Provide practical tools for developers in order to improve software quality.

If you are interested in collaborating with me, have a look at my list of research topics. I’m always open to do cool research through collaborative endeavours.

Formal Education

I completed my PhD in Computer Science in June 2023. I did my PhD in the Department of Software and Computer Systems (SCS) at KTH Royal Institute of Technology, in Sweden :sweden:, under the supervision of Benoit Baudry and Martin Monperrus. My research work was generously funded by the Wallenberg Autonomous Systems and Software Program (WASP), funded by Knut and Alice Wallenberg Foundation. My PhD was about software debloating.1

I also do knowledge-seeking software engineering research, e.g., by extracting useful information from data stored in software repositories.2 In particular, I’m interested in measuring the impact and pervasiveness of software bloat across large-scale software ecosystems.

I hold a BSc and MSc in Computer Science.

A long time ago, I participated in programming competitions.

Here is my minimalistic resumé.


Out of work, I enjoy spending time with my family, reading physical books, and jogging across the Stockholm’s beautiful parks.3
