Hello

About

I help product work start stronger, scale cleaner, and get back on track when execution drifts.

Based in Austria. Remote and EU-based teams.

I step in when direction is unclear, priorities are overloaded, or delivery keeps looping. I clarify ownership, structure the work, and move teams toward a real release — whether that means starting from scratch or resetting what's already stuck.

My background is hands-on: product ownership across web, iOS, and Android, from idea to launch. I also support app store presentation and launch packaging when products need to show up better in the store.

Say hello
If this sounds familiar

We should talk

  • Roadmap keeps changing
  • Decisions do not stick
  • Team is busy, but not progressing
  • Too many opinions slow delivery
  • Work happens, but nothing ships

What I help teams do

When product work gets messy, I help teams find the next right move.

I work best where priorities are overloaded, decisions are slow, or delivery needs someone steady enough to turn complexity into progress.

Turn messy input into a clear plan

I sort through ideas, feedback, constraints, and business needs so the team knows what matters next.

Make priorities easier to defend

I help separate urgent from important, reduce noise, and shape a roadmap people can actually act on.

Keep delivery moving

I keep scope, decisions, developers, QA, and timelines connected so work does not stall in the middle.

Prepare launches with less stress

I bring structure to release details, edge cases, feedback loops, and last-mile decisions before they become blockers.

Shape app store presence

I help prepare apps for launch with clearer store structure, QA testing, listing presentation, and release readiness that support conversion.

Connect product work to outcomes

I keep usability, growth, retention, and team capacity in the same conversation so product work supports the business.

Current collaborators

People I work closely with on active products.

The people I stay in close touch with as we build, grow, and support current products together.

Contact

Need someone to bring order to the product work?

If your roadmap is messy, a launch is coming, or the team needs clearer priorities, send me a note. Based in Austria, I work with both EU-based and remote teams.
