Software Developer | Development Team Lead
Visma | Rex+ · Chile
I'm a software developer and development team lead based in Chile, building web and mobile applications across the stack. I believe software should always offer a solution to a real problem. That's what the S in JosTechS stands for: Solutions.
I care about maintainable code, clear architecture, and practical technical decisions that help teams understand, improve, and evolve their software. That same clarity should reach the people using it: I aim to create accessible, self-explanatory user experiences that make it easy to understand what to do and how to move forward.
I keep learning and exploring artificial intelligence, automation, and new technologies through my work and personal projects, always looking for ways to solve everyday problems and make software more useful.
Technologies and tools I've worked with:
- Frontend: HTML, CSS, JavaScript, TypeScript, React, Next.js, Astro, Tailwind CSS.
- Mobile: React Native, Firebase, SQLite.
- Backend: Python, Django, FastAPI, Node.js, PostgreSQL.
- DevOps & monitoring: Git, Docker, Kubernetes, AWS, Bitrise, Rollbar.
