  • Connected-care portfolio modernization

    Leading the migration of a multi-application portfolio away from end-of-life runtimes (.NET Framework 4.8, .NET Core 3) onto .NET 10 — incrementally, app by app, without freezing delivery.

  • Families companion app

    A mobile app for relatives of the platform's end users. React Native frontend on a microservices backend (Docker Compose), async messaging and a cache layer. My concept was voted #1 in an internal innovation sprint — I now lead a 9-person team extending it.

  • Cloud-API integrations

    Blazor applications integrating with the platform's cloud API to surface new operational capabilities to internal users.

Challenges Solved

The kind of stories an interviewer asks for.

  1. Legacy modernization · technical strategy
    Challenge

    A chunk of the portfolio sat on end-of-life frameworks — blocking security patches, modern tooling and performance work — but a big-bang rewrite was off the table.

    Approach

    Drove an incremental, app-by-app migration to .NET 10, keeping each app shippable throughout and prioritizing by risk and business value.

    Impact

    Portfolio moving onto a supported, modern runtime with reduced risk and a clear path off legacy — without stalling feature delivery.

  2. Initiative · influence without authority
    Challenge

    Families of platform users had little visibility into the care being delivered, and there was no mandate to build anything for them.

    Approach

    Pitched and prototyped a companion app on a microservices + async architecture, then rallied stakeholders behind it during the innovation sprint.

    Impact

    Voted #1 idea of the sprint; now leading a 9-person team across dedicated innovation days to grow the concept.

Growth
This stage turned me from a feature developer into someone who drives technical direction and initiative. I went deep on legacy modernization and architecture, learned to lead a team and sell an idea internally — and started folding AI tooling into the workflow to move faster without letting the fundamentals atrophy.
