About
I build reliable backend and web systems that scale.
I'm Gonzalo, a senior software engineer with 17+ years in startup teams, building Go services, web applications, distributed systems, security, observability, and cloud-native platforms.
These days at Tiger Data, I work on AI engineering, helping teams build agentic workflows and the infrastructure behind them.
In my spare time I build mobile apps with AI coding agents.
