A few words from founders and teams I've shipped real systems with.

n8n workflow rescue

Marcel was incredible to work with. Our n8n workflows were continuously crashing the n8n Cloud server. Marcel pinpointed the problems, proposed a solution, and fully implemented it. Tremendous ROI working with Marcel on this.

Marcel is an extremely knowledgeable professional and a pleasure to work with. We worked together for two months, and I couldn't be happier with the experience.

From day one, Marcel demonstrated a high level of professionalism and a genuine commitment to delivering the best possible quality. He consistently challenged ideas and proposed better solutions, ultimately improving many aspects of what I had originally envisioned.

Beyond his technical expertise, Marcel is one of the easiest people I've worked with. Communication was always effortless, and throughout our two months working together, we rarely needed lengthy alignment meetings because everything progressed so smoothly.

I can wholeheartedly recommend Marcel to anyone looking for a talented, reliable, and thoughtful professional.

Founder sparring

Marcel is one of the most modest, intelligent, and genuinely insightful people I've met on this entrepreneurial journey.

He listened with pure curiosity and kindness and within minutes, he was unpacking my problem statement from angles I hadn't even considered. His out-of-the-box insights, thoughtful questions, and ability to step into another person's perspective were incredibly valuable. It was clear that what Marcel does comes from a genuine passion for helping founders think sharper and grow stronger.

Entrepreneurship can be a lonely journey. Sometimes, what we really need isn't just advice — it's someone who listens actively, challenges our thinking constructively, and helps us see things differently. Marcel is exactly that kind of person.

If you ever get the chance to work with him, I can't recommend it enough. His critical yet empathetic mindset makes every project worthwhile.

Marcel helped me a lot across different areas of my business, from marketing and growth to structure, time management, and clear processes. Marcel quickly sees where the real leverage is. He asks the right questions, brings order to complex topics, and helps define clear next steps.

Thanks to his input, I was able to sharpen the focus of my company, work more efficiently, and grow more intentionally.

Increase your company's productivity

AI workflows that change the way you work.

AI agents take over the recurring work and hand off to each other, so the briefs, follow-ups, and waiting that used to eat a whole day are finished in minutes. Your teams stay on the work that actually needs them, output goes up, and nothing stalls because one person is busy. Building that inside your company is what I do.

Exploring Strategic Opportunities

Senior Full-Stack Architect & Strategic Product Lead

Need a seasoned technical leader to architect complex systems, drive product strategy, and single-handedly build the implementation?

System Architecture

Designing scalable, resilient systems and evaluating stack choices.

"From monolithic decoupling to globally distributed edge services. I design architectures that won't require a total rewrite in 24 months."

Product Strategy

Aligning technical roadmap with your business KPIs.

"Stop building features nobody asked for. Let's align technical execution directly with your core revenue drivers."

Hands-on Implementation

Not just drawing boxes, I actively develop and ship the full stack from database to frontend.

"100% bespoke engineering. I write the code, configure the pipelines, and architect the database. Pure project delivery."
