What Our Clients Say
Proven results for businesses of all sizes.
"Mike combines technical expertise with genuine entrepreneurial thinking – for me he's not just a great developer, but also a reliable sparring partner. He challenges requirements constructively, makes pragmatic suggestions, and never loses sight of the budget or the bigger picture. I value his reliability and honesty: he communicates transparently, keeps his commitments, and is upfront when a different solution – or a different specialist – would serve me better. I can highly recommend working with Mike."
Philippa Dengler
Senior Consultant, Conscha GmbH
"I'm absolutely thrilled with the support from Mike at ESWR! He's incredibly fast, friendly and agile. He coached me excellently and together we found a great solution that didn't cost me a fortune. I kept full freedom to handle my software exactly the way I want, but now backed by his professional IT expertise. What really made a difference is that he showed me what's possible with AI – I learned practical ways to use it that gave me so much more freedom, while still being able to do everything myself. Sometimes you just need the right concept, and that alone propels things forward enormously. A total game-changer for my business!"
Sven Diekena
Owner, Krankenpflege Weyhe
"Working with Mike is refreshingly straightforward. He gets what we're trying to build at LODRESSO and translates it into tech decisions that actually fit a brand-driven business – no overengineering, no jargon walls. He's a real partner: honest about trade-offs, quick to respond, and always thinking one step ahead of where we are today."
Carol Baumgartner
Founder, LODRESSO
"It has been a pleasure to work with the ESWR in the past. Their approach to analyzing and developing solutions was extraordinary. The team has been enriched by powerful experience and expertise in the SAP Commerce Cloud and AWS environment."

Not only did they help us with the development of new features, but they also assisted us in reducing internal manual steps with our software. From start to finish, they were responsive, attentive, and delivered high-quality work that exceeded our expectations."
