Senior Fullstack Developer | DevOps & Cloud

+12 years of experience | Colombia

I'm a fullstack developer with a DevOps focus, passionate about building solutions that actually work. My work centers on transforming business ideas into robust and scalable digital products.

I work comfortably on both frontend and backend, and I enjoy being involved in the entire chain: from architecture design to automated deployment. I've worked with diverse teams, leading complex migrations, optimizing cloud infrastructure, and establishing CI/CD pipelines that make everyone's life easier.

I work with multiple languages and technologies depending on project needs: JavaScript/TypeScript, Python, Java, and PHP are part of my daily work. On the infrastructure side, I handle AWS/GCP, Docker, Terraform, and pipelines with GitHub Actions. For frontend I work with Next.js, React, Angular, and mobile development with React Native and Flutter.
