Marc L.-Full-Stack Product Engineer | UX/UI Designer

Hi, I’m Marc.

For 15+ years, I’ve been working on concept development, digital implementation, branding, and web design. I help companies and start-ups develop digital presences and applications that are well thought out, look modern, and run professionally from a technical perspective.

For me, it’s about solutions that work and are consistent – not quick throwaway prototypes, but systems that are built to last, fit together logically, and meet production-level security requirements.

To achieve this, I combine design with technical implementation. I use modern, AI-supported workflows (Vibe Coding) as an efficiency lever. I strategically plan the logic, data flows, and client connections. AI writes the code, while I guide the architecture, control the logic, and turn everything into a premium UI/UX design.

• How I work

• the goal defines the process

• clear structures as a foundation

• combining aesthetics and function

• direct communication on equal footing

• substance over short-lived trends

• What I do:

• Web & Interface Design: Conceptualization and design of modern interfaces (e.g., dashboards, admin tools, and client apps).

• Full-Stack Product Structure: Planning integrated systems with multiple applications to avoid code duplication.

• Databases & Permission Models: Conceptualization of secure data structures (Supabase/PostgreSQL), including well-designed access controls.

• Complex Business Logic: Modeling and automating demanding processes in the background (e.g., time-controlled workflows).

• Clean Data Management: Structured, traceable version control of database changes as a reliable foundation.

• Who I work with: I work with companies and people who are building something of their own and value substance in design and code. If you need support with a complex platform, get in touch.

I look forward to hearing from you. Marc
