jpolec/README.md

Hi there 👋

I'm Jakub.

I'm a founder of QuantJourney, a modular buy-side investment platform (IBOR/PMS, instrument master, portfolio state, MCP/API access) built for hedge funds, family offices and asset managers.

I work at the intersection of AI, quantitative investing and financial infrastructure - building AI-native research and investment systems.

My Background

physics (University of Warsaw, CERN), 20+ years in technology (Microsoft, Oracle, T-Mobile/Orange), three startups, one exit. In quantitative finance since 2020.

What I'm building

My writing

Working with me

Open to a small number of architecture and build engagements per year, with companies embedding AI into their investment workflows. Defined discovery, architecture, and build phases. If that's what you need, check detailed scopes at consulting.
