About

11/24 — now

At Wellcosan, I'm picking up right where I left off over the past few years - building the best Shopify stores, empowering teams, and taking the reboots.com and venenengel.de brands to the next league. Leveraging my experience from previous roles helps me to keep on top of things, maintain focus and deliver results. I love driving growth and innovation as part of the Performance Marketing team.

Stepping into the vibrant world of sushi-bikes.com, I took the helm to engineer the Shopify e-commerce platform, ensuring smooth operation and success.
I implemented a subscription model, executed a complete redesign in record time, boosted performance with all Core Web Vitals in the green, and established a professional CI/CD pipeline. On mobile, I tripled the click-through rate.
While financial constraints eventually threw a stick in the spokes, this experience reaffirmed my passion for innovation and delivering outstanding e-commerce solutions.

Taking a hands-on role, even in the middle of personal commitments, and representing the company at Shopify events, emphasised my unyielding drive.
