What I'm looking for

I’m looking to build and modernize Angular/Ionic products, lead micro-frontend and clean-architecture work, and collaborate in Agile teams—shipping performant systems with strong API and cloud integration.

I’m a results-oriented software developer with 5+ years of expertise building, migrating, and maintaining complex web and mobile applications. I specialize in Angular, Ionic, and .NET environments, and I enjoy turning messy requirements into clean, scalable systems.

Across my roles, I’ve supported high-demand applications by creating complex data structures and building scalable solutions with clean architectures. I’ve also led front-end architecture decisions such as creating front-end archetypes and structuring reusable components for micro-front-end structures.

In the cloud, I’ve developed and maintained .NET Core applications and mobile apps hosted on Azure services, including mobile application management and deployment. I focus on performance and maintainability, pairing architecture like Onion Architecture with practical engineering habits such as Git, Agile/Scrum, and CI/CD.

In my current work, I update Angular applications to the latest versions, maintain Umbraco CMS applications, review and work on APIs with Amadeus integrations, and create microservices. I’m seeking opportunities where I can keep improving usability and deliver high-quality software using strong problem-solving and clean architecture.
