Who are you? ×

My name is Celeste Naranjo.

I’m not just a coder—I’m a dedicated full stack developer who believes in building digital solutions that truly make a difference. My journey in development started with a passion for technology and design, but over time, it has grown into a mission: to help individuals, startups, and businesses transform their ideas into functional, scalable, and user-friendly applications.

What sets me apart is not only my technical skill set but also my approach to problem-solving. I see every project as more than just lines of code. To me, it’s about understanding your vision, your goals, and the challenges you face. By combining creativity, logic, and precision, I’m able to deliver solutions that don’t just work—they create impact.

As a full stack developer, I bring expertise in both front-end and back-end technologies, bridging the gap between design and functionality. From creating intuitive interfaces that enhance user experiences to developing robust backend systems that ensure security and scalability, I take pride in delivering end-to-end solutions.

Ultimately, my focus is on collaboration. I believe the best results come from working closely with clients, listening to their needs, and turning their vision into reality.

Career Timeline

I’ve worked on brands, websites, apps, and design systems. To me, it’s all the same. It’s understanding the problem and finding a creative way to solve it.


What do you do? ×

I am a Freelance Full Stack Developer.

I’m most useful on projects where strategy, user experience, and visual design come together with full-stack development to create polished, scalable, and reliable digital products.

  • Design

    Strategy, experience, and visuals merge here. From asking the right questions to understanding users and crafting meaningful interfaces, I make sure every interaction and element has purpose. As a full stack developer, I don’t just design for looks—I design for usability, accessibility, and performance.

  • Development

    This is where creativity meets technology. Whether front-end or back-end, I build applications that are fast, secure, and scalable. From responsive UI and cross-platform compatibility to database management, API integrations, and cloud-ready solutions, I deliver complete systems that balance functionality and performance.

  • Deployment

    A digital product isn’t complete until it’s live. I handle everything from server setup, CI/CD pipelines, and staging environments to testing and optimization. As a full stack developer, I ensure smooth launches, ongoing reliability, and the ability to scale as your product grows.
