What I'm looking for

I’m open to remote international roles.

At B2B Reservas, I reworked the core product platform to improve its architecture and long-term maintainability. I’m also contributing across product conception, database design, architecture, frontend, backend, and scalability for three strategic innovation products.

I lead the team’s adoption of Claude Code and AI-assisted engineering practices, coaching developers to use these tools while maintaining code quality and engineering standards. I also partner with product stakeholders and mentor engineers on technical decisions and implementation.

At Ezoom, I progressed from Software Developer to Tech Lead within nine months and led a team of more than seven developers. I led end-to-end product development and contributed to reducing API response time from 3 seconds to 150 milliseconds through architecture and performance improvements.

As co-founder and Software Architect at Prosperapps, I delivered digital products for football clubs, healthcare companies, and content creators, including web, mobile, and real-time software. Earlier, at Embber and Smarte Estrategias, I developed web applications and internal software and contributed to AR/VR experiences.
