Summary
Hi, I'm Marc.
I'm a Full-Stack Product Engineer and UX/UI Designer based in Hamburg. I plan, design, and develop websites, web applications, and digital products – from the first idea to launch.
You can come to me with an idea, a specific problem, or an existing product. We'll find out what's needed. From there, I develop and implement a solution.
I connect what happens technically behind the scenes with what people see and use. I question existing approaches and also take unconventional paths when they lead to a better result.
At a glance:
- B2B & B2C
- independent projects & team support
- concept to launch or individual project phases
- Remote & Hamburg area
- direct collaboration
Focus and implementation:
- Concept: analyzing requirements, questioning existing approaches, and conceptualizing digital products.
- UX/UI Design: information architecture, user guidance, and designing distinctive interfaces.
- Full-Stack Development: architecture and development of integrated applications and websites (frontend, backend, monorepo structures).
- Databases & Permissions: data modeling with Supabase / PostgreSQL, authentication, and role-based access controls.
- Business Logic: developing custom business logic, interfaces, and automated, scheduled processes
I feel most comfortable between things. I don't design or develop solely for the sake of aesthetics or usability. What I really want is to build bridges. Bridges between people and ideas.
I want to keep the entire architecture of a project in view. At the same time, I'm just as happy to get lost in a detail until it finally does justice to the original idea.
I look forward to hearing from you. Marc
