Back to original languageAbout David
đź‘‹ Hello! I am a frontend web developer, passionate about creating fluid, useful, and well-thought-out interfaces.
I started my career as a backend Ruby on Rails developer, which gives me an excellent understanding of server-side issues, APIs, and data structuring today. Gradually, I moved towards frontend development, a field in which I thrive: where design, technology, and user experience meet.
🎯 What I offer:
- Development of high-performance frontend interfaces (React, Next.js, React Native)
- Pixel-perfect integration of Figma mockups / design systems
- Connection to APIs & fine-grained business logic management
- Refactoring or migration of existing applications
- Creation or complete redesign of dashboards, business tools, PWAs, or MVPs
🛠️ Preferred Stack:
React / React Native · TypeScript · Next.js · TailwindCSS · Ruby on Rails · PostgreSQL · Heroku · GitHub
đź’ˇ My Strengths:
- Solid background in backend Ruby on Rails
- Smooth communication with product, design, and tech teams
- UX rigor & attention to detail in UI
- Clean, maintainable, tested (when necessary), and documented code
- Good humor, autonomy, and product culture ✌️

The Hacking Project
Reviewed on 4/7/2021
David and 3 other developers were tasked with mentoring 120 students in a Digital Marketing Master's program to teach them the basics of coding. In one week, students had to learn HTML, CSS, Bootstrap, and version control with Git & Github. Mentors were available to answer all questions about the course and also gave supplementary lectures.
The mission was a success: students were satisfied with the mentoring provided, finding it very useful. The results of their final projects prove it. Overall, David proved to be very pedagogical, involved, and available, even exceeding the set hours to help students who were struggling.
