Hello, I'm
Jery Rodríguez Fdz.
🚀 Full Stack Developer, Computer Science Major & Math Lover
I enjoy working with applied mathematics and bringing that analytical mindset into computational development. I work closely with teams to ship scalable applications, strengthen backend systems, and craft visual designs that elevate the overall user experience. Right now I’m deepening my work in artificial‑intelligence architectures and advanced neural‑network design, focusing on their optimization, training, and deployment in real‑world environments.

About me
More about me 📖
I’m currently completing my studies in Computer Science at the University of Havana. I design and develop digital solutions focused on business, visual clarity, and technical scalability. I work with cross-functional teams to build consistent products aligned with real goals. I also do visual design, creating clean interfaces and graphics in Photoshop. You can reach me through any of my social platforms — preferably via Telegram — and I’ll get back to you as soon as I can.
