What I'm looking for

I seek senior engineering roles where I can lead technical teams, improve product and observability, reduce tech debt, and collaborate cross-functionally to drive measurable business impact.

I am a senior software engineer with over 14 years building web applications and leading engineering teams to deliver business outcomes. I specialize in JavaScript (React, Node.js), Ruby on Rails, and a wide range of relational and NoSQL databases.

At Handshake I led squads as Web Technical Leader, launched revenue-driving experiments like Handshake Plus (Stripe integration), improved observability with Datadog, and served as Incident Commander during on-call rotations. I focus on quality through code review, reducing technical debt, and modernizing platforms.

As a frontend lead at Zemoga and a technical lead at Gases del Caribe, I delivered design systems, e-commerce features, financial systems, biometric pilots, and other solutions that earned additional engagement and recognition. I also led cross-functional partnerships with Product, Analytics, and Marketing to analyze experiments and improve product performance.

I bring strong leadership, mentoring, and communication skills, with a proven track record of shipping measurable improvements, driving revenue, and improving team practices and documentation.
