Who I am

I help ambitious companies turn ideas and business challenges into digital products that are clear, intelligent and built to grow. Not a dev shop. Not an agency. A single point of thinking and execution.

More about me

Based in Berlin, I work independently with founders and teams who need more than execution. Strategy, full-stack engineering and AI integration, without the agency layer in between.

I work across strategy, product design, full-stack engineering, and AI integrations.

  • Information architecture
  • User flows
  • Tech foundations

Turning an idea into a clear, buildable system. Shaping the product, defining how the pieces connect, and the technical decisions that will define the codebase for years to come.

Flow

Process for turning ideas into real, working solutions that deliver amazing results.

Process:4 steps
Duration:~ 1 month

Discover

Before proposing anything, I take time to understand what you're really trying to solve.

Design

We shape flows, architecture, and key decisions together. For platforms, this is where the most important work happens.

Build

Clear milestones from day one, so you always know where things stand.

Launch

I ship, monitor, and stay close after launch to make sure everything lands right.

Pricing

I keep pricing clear and fully transparent. Final cost depends on scope and timeline.

Custom Software & AI

Admin panels, platforms, API integrations, and AI-powered automation, scoped to what the project actually needs.

FAQ

Have some questions?

Every project is scoped to the actual work, not the hours. After a first conversation I send a fixed proposal with a clear deliverable, timeline and price. No retainers, no open-ended invoices, no surprises once the scope is agreed.

Not finding answers?

Reach out anytime. I'm happy to answer any questions before you commit to working together.
