I’m Juan, a Senior Full-Stack Web Developer with extensive experience building reliable, scalable web applications for growing businesses and startups. I specialize in taking projects from idea to production and keeping them healthy long after launch. I handle the full lifecycle: planning, technical decisions, development, deployment, and long-term support. I’ve built SaaS platforms, internal tools, ERP and CRM systems, and data-driven applications, always prioritizing performance, stability, and clean, maintainable code. On the front end, I work primarily with React and Next.js to deliver fast, modern user experiences. On the back end, I have strong experience with Node.js, Python, and Ruby on Rails. I design and integrate REST APIs, work extensively with PostgreSQL and Supabase, and build systems that scale cleanly and are easy for other developers to understand and maintain. I’m comfortable owning features end to end from concept to production and post-launch support. I also bring hands on experience with WordPress, Drupal, Vue.js, JavaScript, and TypeScript, allowing me to jump into existing codebases quickly and add value without slowing your team down. Whether you need to extend an existing application, reduce technical debt, or build a new product from scratch, I focus on delivering dependable solutions you can trust. Have a project in mind? Let’s chat and map out a smart solution that actually delivers.
