ABOUT

Agustín Avellaneda

Independent Product Engineer

PM and Fullstack Developer, founder of Excelso. Catamarca, Argentina. I started far from where these stories are supposed to start: with a Mining Technician degree and months of field work in Salar del Hombre Muerto. None of that sounds like a developer. And yet that's exactly where I learned what I use every day: that a complex system isn't understood by looking at one piece, but at the relationships between all of them. I solve real problems with simple tools. I'm not interested in technology for technology's sake; I care about what changes in someone's life when the product works. I'm a PM because I need to organize. I'm a developer because I need to execute what I organize. An MBA (700 hrs, 2026) adds the business lens: strategy, finance and leadership.

HOW I THINK

What drives me

Solving real problems with simple tools. I'm not interested in technology for technology's sake; I care about what changes in someone's life when the product works.

How I work

Discovery before specification, specification before implementation, review before closing. Direct work with founders and product leads, no intermediate PM. Short meetings, clear deliverables, constant iteration.

What I'm looking for

Interesting problems, teams that value clarity, and products where technical quality matters because the product matters.
