Summary
🤩
Rockstar🎓
Top SchoolJaakko Luttinen is a Lead Data Scientist with 14 years of experience specializing in Bayesian modelling and scalable inference for large, complex datasets. He drives production-ready solutions for time series forecasting, missing-data reconstruction, and user behavior prediction, combining strong numerical programming skills in Python, C/C++ and Matlab with parallel-computing experience (OpenMP, MPI). A former PhD student at Aalto University working on latent Gaussian spatio-temporal models, he bridges deep academic expertise and pragmatic engineering at Leanheat. He is the author of the BayesPy open-source package and contributes to community projects—from improving Spacemacs workflows to clarifying documentation and licensing on Bayesian tooling—reflecting attention to usability and reproducibility. Based in Tampere, Finland, he pairs a functional-programming interest (Haskell) with hands-on system improvements, quietly favoring robust, well-documented code over flashy prototypes.
