Engineer first.
Leader always.

I build systems that stay fast under pressure, stay maintainable as teams grow, and stay aligned with what the business actually needs.

Over the past 14 years I've worked across startups and scale-ups in Chile, Venezuela and Spain — writing code, leading migrations, mentoring engineers, and taking the CTO seat when the moment called for it.

Today I work as Lead Backend Engineer at KenTech, and I'm selectively open to consulting engagements and senior engineering opportunities that offer genuine technical depth.
