What I'm looking for

I'm looking to build scalable SaaS platforms and automated business solutions while continuing to learn new technologies, collaborate with multidisciplinary teams, and deliver high-quality code that meets business objectives.

I've built VendingVolt, a platform connecting vending machines to real-time sales analytics, inventory alerts, Stripe payments, and WhatsApp notifications. I also delivered an e-commerce platform for Hacienda Los Huajes, a state-level recognized tequila brand.

Across SoluTurno, CrypTasks, and SoluWeb, I've owned the full software lifecycle from analysis and design through coding, testing, and deployment. I build with React, Next.js, Vite, Angular, Node.js, MongoDB, Supabase, and Stripe to create scalable SaaS products and responsive web experiences.

As a Software Development Engineering student at ITESO, I previously improved accounting-system reliability at Despacho Castellanos through Excel automation and cross-functional software integration.
