About Juneiker Leonel

Full Stack Developer specialized in PHP, Laravel, React, Next.js, Flutter, and Firebase with over 5 years of experience building scalable digital platforms in production.

I target companies and startups that need robust technological solutions: from multi-vendor eCommerce and mobile applications to operational management systems and innovative POS systems. My differential value lies in combining deep technical knowledge with business vision — I don't just write code, I build products that work and scale.

I have led operational projects in the European market, including delivery platforms with thousands of orders managed, POS systems with auto-printing and background notifications, and digital ecosystems with third-party integrations (CJ Dropshipping, delivery companies, payment APIs). I also have experience in digital marketing, which allows me to understand the conversion funnel and optimize both the frontend and the acquisition strategy.

I am an active member of the Google Developer Program (Google Cloud Innovator, GDG Member, I/O 2026) and maintain technical documentation in English with professional accuracy.
