About me
I help E-Commerce leaders in D2C Manufacturing & Retail brands challenged with converting complex products and returns, so that they can see +15% AOV growth, ~60% decrease in support tickets.
For over 15 years, I've helped 30+ E-Commerce teams (including enterprises like ALDI, Hornbach, Meusburger, Lekkerland, Certeo) to launch in 16x countries, scale up to 50,000 order/min or 300M-3B EUR GMV each.
Ex-Chief Architect @ Spryker
Led the technology roadmap across 11x product offerings in 5x product lines, scaling platforms used by 150+ enterprise customers operating €15B+ GMV and ranked #1 in Gartner B2B Commerce & Complex Business Models.
What Leaders Say
“Very early on, I realized that with Denis leading the architecture for the App Composition Platform, we were in safe hands. His experience allowed him to see how an architectural choice impacts different parties, including customers, developers, partners, and security. Apart from technology, Denis has a very deep understanding of Commerce. With AI becoming a table stake in every domain, especially in commerce, Denis's experience will be extremely valuable to companies and platforms alike that want to enhance their Commerce systems, with or without AI.”
“Denis played a central role in defining Spryker's core architecture and product direction during our key growth years. As Chief Architect, he helped evolve Spryker from an early-stage product into a global commerce platform now recognized by Gartner as a Leader. His rare combination of technical depth, business understanding, and execution discipline shaped many of the platform decisions that still drive value for customers today.”
“Denis was my lead architect and later my successor at Spryker. He quickly mastered the scope and complexity of the system and led the core architect team with confidence. He is always at the forefront of technology and highly enthusiastic about AI. Besides being a strong Chief Architect, he is a great team player, a hands-on developer, and I still enjoy brainstorming with him, even years after we worked together. I highly recommend him for CTO or equivalent roles that require deep technical skill, a pragmatic approach, and entrepreneurial spirit. I am happy to provide a reference call anytime.”
What I usually see behind E-Commerce storefront
Common challenges that slow down growth and drain resources
Insecure AI Rollouts
Unstable 4+ months to first-customer AI programs without safety guardrails and frustrated customers and unclear metric and ROI.
Performance bottlenecks
Under real traffic e-commerce platform cracks with slow page response, timeouts, and unstable stock or long order updates.
Data chaos
Product, stock, and pricing data live in disconnected systems. Sync jobs fail, manual fixes pile up, and no one fully trusts the numbers, slowing decisions and creating customer-facing errors.
Integration and middleware pain
Too many moving parts between ERP, PIM, and storefront. Each change triggers a chain reaction of bugs and sync errors, leaving teams firefighting instead of improving the platform.
Scaling challenges
As the business grows, your technology and processes stop scaling with it. Teams duplicate logic, integrations multiply, and every new feature adds complexity instead of leverage, making growth harder, not easier.
Long release cycles
Your roadmap keeps slipping; every feature, integration, or deployment takes weeks longer than planned. Delivery slows, dependencies grow, and innovation stalls under process and technical debt.
