About

About me

Ricardo Barroca

I'm a self-taught software developer, and the passion came from entrepreneurship. Long before AI made building easy, I had a vision β€” and I had to learn to code so I could ship it myself.

Financial markets were the first obsession. I started building trading strategies and algorithms that actually made money, which landed me at GR Financial Group β€” where three years of R&D produced live quant strategies that have generated +$10M for the firm, and kickstarted my journey into algorithmic trading.

From there I fell in love with AI agents β€” way before β€œAI agent” was a buzzword. At Dengun I led the AI innovation R&D track, shipping production agents and end-to-end automations before the rest of the market caught on.

Today I'm building my own quantitative predictive-markets fund, Polytier β€” specializing in predictability models across weather forecasts, crypto prices and sports outcomes, combined in an orthogonal approach to extract alpha.

Apps, SaaS, trading systems, agents β€” whatever the stack, the bar is the same. I ship.
