About Matias

I help companies modernize their outdated applications to innovate faster and operate more efficiently. By updating or completely redeveloping legacy systems with modern, future-proof frameworks, I help organizations unlock their full technological potential.

Additionally, I bring experience working with a multinational healthcare company, giving me a deep understanding of complex requirements and transparent communication within larger organizations.

What sets me apart is my close collaboration with clients and stakeholders. I guide projects from analysis to implementation, communicate clearly, and deliver real value. My project experience includes modernization projects, greenfield developments, and system integrations, always with the goal of creating sustainable and maintainable software solutions.

    July 2024 - Today (1 year and 11 months)
    Munich, Germany
    I have extensive experience working with a large multinational corporation where I played a key role in the redesign and modernization of their entire Case Management Software (CMS). This involved collaborating with cross-functional teams, improving workflows, restructuring data models, and helping define the technical direction of a mission-critical product used across the organization.

    In parallel, I’ve built a wide variety of smaller projects and applications, such as internal tools, process automations, dashboards, and standalone services—always with a strong focus on clean architecture, maintainability, and real-world impact.
