Summary
👤
Senior🎓
Top SchoolAitor De Latierro Olivella is a founder and lead data scientist based in Barcelona with 11 years of experience building predictive and prescriptive analytics for commercial and web-scale systems. He combines strong academic training in computer science and telecommunications with hands-on work in time-series forecasting, metaheuristic optimization for territory alignment, and adaptive assignment heuristics. As founder of KaizenAI and former data scientist at Kaizen for Pharma and Arcvi, he has taken models from prototype to production across sales, marketing, and operations domains. He is also an active back-end open-source contributor, having optimized prime-factorization and primality routines in the high-performance Julia language and implemented wallet and consensus-adjacent improvements in the Sia blockchain. This blend of low-level algorithmic optimization and applied ML lets him squeeze performance from both code and models, often surfacing edge-case robustness through improved testing. Colleagues would describe him as an entrepreneurial engineer who prefers principled, performant solutions over quick fixes.
