Summary
🤩
Rockstar🎓
Top SchoolAlejandro Feliú is a Bayesian inference researcher and software developer with 11 years of experience, currently working at PlantingSpace after completing a PhD in Bayesian Machine Learning at Aalto University. He combines deep probabilistic modeling expertise—focused on robust Bayesian inference—with practical engineering, shipping reproducible code and tests across research and production settings. A prolific open-source contributor, he has improved core tooling such as HaskTorch (Haskell bindings for neural nets) and enhanced the widely used Spacemacs editor, reflecting strong systems and language-agnostic skills. His background spans academia and industry roles in data science, teaching, and renewable energy forecasting, showing an ability to bridge theoretical advances and real-world impact. Colleagues describe him as a creative problem-solver who prefers to “solve problems just once,” automating correctness via test-driven fixes in complex probabilistic codebases.
