18 years designing systems that cannot go down. For the last three I apply that to markets: real-time data, reproducible backtesting and automated execution. I trade what I build and publish the full track record.

Who I am

José Franco

Software architect · Tech Manager at Globant · Buenos Aires 🇦🇷

I started as a .NET developer in 2006 and moved through Technical Leader, Software Architect and Chief Software Architect. 18 years building software — Cloud and DevOps came later, as tooling, not as identity. Today I am a Tech Manager at Globant.

On my own time I build algorithmic trading systems: real-time data, reproducible backtesting and automated execution. I trade what I build and publish the entire track record — drawdown and red days included.

How I collaborate

I build with people, not for people.

I have a full-time job I like, so this is not a consultancy. These are my own projects looking for technical partners, plus occasional collaboration when the problem is worth it.

// 01

What I bring

18 years designing systems that cannot go down, applied to markets: real-time data, reproducible backtesting and automated execution. If the problem is making an idea work in production and not just in a notebook, that is where I am useful.

🤝

// 02

What I am looking for

People who ship code — Python, Go, cloud — and are curious about markets. Traders with a documented edge who want it turned into a system. And anyone with opinions about point-in-time data.
