Gerardo Ruiz
CTO & Lead Engineer
Chile
I am an architect and builder of SaaS platforms that scale. Over the past 9+ years, I've led the technical strategy and hands-on development of products across EdTech, environmental compliance, IoT, and logistics — from system design to production deployment. I specialize in end-to-end system architecture for multi-tenant SaaS platforms, technical leadership across cross-functional teams, and deep expertise in the Laravel/PHP ecosystem. I have a pragmatic approach to shipping, utilizing CI/CD, PHPStan, automated testing, and zero-downtime deploys. Most recently, I designed and built a multi-tenant EdTech SaaS platform. Previously, I architected a compliance SaaS platform and built IoT integrations with Azure. Core skills include PHP, Laravel, Node.js, Vue.js, Docker, AWS, Azure, REST API Design, Multi-Tenant Architecture, System Design, PostgreSQL, MySQL, Microservices, CI/CD, Agile. Open to CTO, Software Architect, and Senior/Staff Engineer roles.
