Summary
👤
Senior🎓
Top SchoolLeon Štok is a quantitative trader and builder of high-throughput alpha discovery systems with 8 years of engineering experience, currently running a prototype that trades ~1,000 assets across stocks, FX, ETFs and commodity futures. He designs and implements ML-driven, self-improving trading infrastructure—authoring a custom JIT compiler, genetic programming pipelines, and a GPU-accelerated distributed backtester—having rewritten his platform a dozen times and written over half a million lines of code. Previously he cut infrastructure costs 35x by porting Python services to Rust and worked on petabyte-scale data pipelines, blending systems-level optimization with quantitative research. An entrepreneur and ex-cofounder, he moves rapidly between building company-grade systems and hands-on R&D, now transitioning from a learning phase into active AUM growth. Based in Zagreb, he pairs deep technical craft (Rust, CUDA, Polars, HPC) with ambition to launch a hedge fund as a lever for broader impact. An avid self-learner and aspiring rejuvenation athlete, he frames engineering as the vehicle to scale beneficial change.
