Hi, I’m Juan (aka John Kleinad). I build clean, scalable web and mobile applications with a strong focus on UX and performance. I’ve led and shipped projects for startups and organizations—from custom CMS dashboards and admin panels to cross-platform apps with push notifications and offline support. I’m also an AWS community organizer in Mexico and enjoy helping teams deliver cloud-native products. Open to part-time or short-term freelance work (10–25h/week).
