Turning ideas into digital products
Computer Systems Engineer with 4+ years leading the web development department at Connectinc, managing 250+ projects: WordPress sites, Flutter mobile apps, Full Stack web systems (React, Next.js, Node.js) and automation with Python and artificial intelligence.
I specialize in custom WordPress development (themes from scratch, plugins, API integrations), cross-platform mobile apps with Flutter, modern Full Stack development (React, Next.js, Node.js) and VPS server administration focused on performance and security. I also integrate artificial intelligence (agents, chatbots and process automation) and Stripe payments to drive real business results.
I work remotely from Querétaro, Mexico, and I'm open to international projects.
