Building software. Exploring how AI changes the way we engineer it.
A little context
An engineer’s craft.
A technical leader’s perspective.
My career has grown through building software, leading technical teams, and sharing what I learn. Today, I work as a Senior Software Engineer at Mercado Libre, hands-on in a large-scale engineering environment.
My experience as a Tech Lead shapes how I approach architecture, technical decisions, and collaboration. Teaching and speaking are another part of that same work: making complex ideas easier to understand.

Selected experience

PreviouslyTech Lead
Led technical decisions and mentored engineers across frontend, backend, and data workflows in highly regulated environments.
Current focus
Learning through building
AI is changing the code.
And the process around it.
Alongside my work as a Senior Software Engineer, I’m experimenting with AI-assisted development workflows. I’m interested in how developers and coding agents work together—and what it takes to keep that work reliable.
- Collaboration
- Clear specifications, agent roles, and orchestration.
- Context & tools
- Giving agents the right context and capabilities, including through MCP.
- Engineering quality
- Guardrails, review, and validation throughout the development lifecycle.
An ongoing exploration, grounded in software engineering.
Teaching & speaking
Knowledge is better shared.
As an instructor and speaker, I’ve taught software development and communicated technical concepts. Explaining how something works is an important part of how I learn, too.
