About Me

Full Stack Developer with over 4 years of experience in technology and more than 3 years as a QA Engineer. My experience across both areas shapes how I approach development, combining full stack engineering with a strong focus on quality, security, and testing. I don't just build features, I also test them, secure them, and make sure they're ready for production.

In my most recent projects (Vertex360, Centro Calm) I designed and shipped complete web platforms for clients in Santiago, including integrated payments, CI/CD pipelines and a full security layer.

I am now looking for a Full Stack role where I can keep building to that same standard. Fast to ship, hard to break.

Vertex360

I built the complete frontend of Vertex360, the website of a mixed martial arts school in Santiago (discipline catalog, coach profiles, schedules) with end-to-end integrated registration and payment.

I built a multi-step registration flow with Chile-specific validations (RUT, age of majority), integrated the Webpay payment gateway from Transbank and connected the site to an external real-time catalog API. I applied 6 HTTP security headers, rate limiting and server-side validation, on a mostly static architecture with CI/CD.

Centro Calm

I led the production launch of Centro Calm, the website of a martial arts and wellness center in Santiago (disciplines, coaches, schedules, contact) with integrated registration.

I built the complete frontend (Next.js/React) and owned the whole infrastructure cycle. I created the repository, designed the production Docker image and configured the CI/CD pipeline in GitHub Actions to publish to GitHub Container Registry. The backend was developed by a third party; my work was integrating the frontend and guaranteeing a reproducible end-to-end deployment.
