Industry Experience

    ImpactSnap — European e-commerce growth through SEO and GEO

    I helped ImpactSnap move beyond Amazon and separate sales channels by building a stronger European brand presence around its own webshop.

    My work combined product experience, consistent branding across online touchpoints and an SEO strategy based on the language golfers actually use. I also developed a GEO layer designed for visibility in AI-generated answers, using clear FAQs, statistics, professional reviews and product pages supported by credible expert validation.

    Rather than treating the webshop, content and search visibility as separate projects, I approached them as one connected customer journey and remained involved in the ongoing marketing. This case is relevant to e-commerce, technical SEO, content strategy and brands preparing for both traditional and AI-assisted search.

    Grenspret — from founder idea to app launch and national press

    I helped turn Kevin’s long-standing idea into a live product for iOS and Android. Grenspret calculates whether travelling to Germany, Belgium or Luxembourg for fuel or groceries is worthwhile.

    I helped define the scope, build the native app through one shared codebase, connect live pricing data and create the calculation and cost-splitting experience. The project also included a focused landing page, app-store optimisation and the marketing launch.

    Grenspret went live on 6 May 2026 and received coverage in de Volkskrant during its first week. This case shows how I combine product thinking, technology and go-to-market execution instead of treating development and marketing as separate assignments.

    Hanova — growing an established webshop without breaking the stack

    I helped Hanova bring its webshop and online marketing together while protecting the systems the business already relied on. The company had an established setup involving inventory management, ERP and partner integrations, so replacing everything was neither necessary nor responsible.

    I reviewed the existing tools and connections, shaped clean transitions, developed the webshop trajectory around those constraints and connected the marketing work to the commerce environment. The updated online layer works alongside the existing processes, followed by ongoing support across marketing and technology.

    This case is particularly relevant to website, e-commerce and integration projects where continuity matters as much as improvement.
