Andrés

I am a Full-Stack Software Engineer with over 5 years of experience, specialized in backend development with .NET and Java, and strongly focused on clean architecture, production-ready systems, and cloud environments. Currently based in Zurich, I have worked on high-demand international projects, including the end-to-end development of a payment gateway for 5-star hotels, from architectural design to production operations on Azure.

My strongest expertise is in ASP.NET Core, REST APIs, and microservices, with hands-on experience integrating payment providers, optimizing databases, and ensuring reliability in mission-critical systems. On the frontend side, I have worked with React and Vue, and I can easily adapt to other frameworks such as Angular when required. I also have solid experience with Docker, Kubernetes, Git, and Azure DevOps, managing deployments, repositories, and environments.

I am looking for freelance projects where I can add value from day one. I’m happy to start small if needed—my priority is understanding the client’s context, delivering clean and reliable code, and building long-term professional relationships. I can work as a backend-focused or full-stack engineer, always with a practical mindset, technical ownership, and a strong focus on results.
