About.
Why clients trust me with their projects.
I'm a Frontend Developer with over 7 years of experience building web applications for companies across Europe and the Americas. My core stack is Vue 3, Nuxt 3, and TypeScript. I also work full-stack with React/Next.js and Python/FastAPI backends when projects require it.
I work with modern technologies like Vue 3, Nuxt 3, TypeScript, React, and Next.js to build solutions that are fast, reliable, and easy to maintain. I focus on understanding your goals first, then choosing the right tools to get there.
Clients come back because I deliver on time, communicate clearly, and care about the end result. I hold a Computer Science degree from UCI (Cuba) with specialization in Java and OOP, and participated in ACM-ICPC competitions.
