What I'm looking for

I'm looking to build AI-powered and scalable software platforms where I can lead architecture, develop backend systems, and apply agent orchestration and modern cloud technologies.

I'm developing AI-powered features for SalesCloser's AI sales platform, using PHP, Laravel, Vue.js, and Python while building agentic development pipelines with multi-agent orchestration. Previously at Onfly, I maintained and developed Latin America's largest corporate travel platform using Node.js, PHP, Laravel, Lumen, and Swoole.

I've led backend teams and architected modular Domain-Driven Design systems supporting thousands of athletes at GTec. Across Gideons International, Evercode Web Solutions, Multdata, and independent consulting projects, I've delivered systems for major companies, pharmacies, businesses, and large member organizations using PHP, Laravel, Node.js, Vue.js, microservices, and cloud technologies.
