About me

Who I am

Software development and technology applied to finance and artificial intelligence.

I started in tech and finance by founding Puerto Finanzas, a community and market analysis platform for capital markets in Argentina.

Over the years, I worked in software engineering, data, and quantitative finance across financial and brokerage firms including Matba Rofex, Bull Market Brokers, and Cohen.

I co-founded Parra Payments, developing software and QR payment solutions for the restaurant industry. We led the company from its earliest stages and investment with DC Ventures through its acquisition and merger with Eastern Point Trust Company (NEMI) (read article on the journey and lessons learned).

Currently, I focus on software architecture, developer tooling, and applied research with artificial intelligence agents.
