Product development on TOTO's casino and sports-betting platforms: high availability, huge traffic spikes, and strict compliance with online gambling legislation.

• Part of the team that rebuilt the entire casino platform on Vue 3, a custom Node.js/Express SSR solution and a .NET backend, hosted in Azure
• Helped build TOTO Sport, a real-time sports betting platform, reusing the casino stack to ship faster without sacrificing performance or compliance
• Created reusable front-end components across products, set up monitoring and alerting, and integrated user tracking via Google Tag Manager
• Integrated the new Winn-It brand into the legacy casino platform and connected third-party APIs

Built and ran high-traffic entertainment products — video, puzzles, casual games, quizzes and podcasts — used across major Dutch media brands such as AD, HLN and de Volkskrant.

• Created front-ends from scratch for products that ran both as standalone destinations and as embeds inside news articles
• Implemented advertising, user tracking, paywalls and custom A/B-testing solutions for embeddable products
• Owned operations under a "you build it, you run it" principle: containerized hosting in AWS, monitoring and alerting

Led front-end development (75% hands-on, 25% leading) in a fast-paced B2C campaign environment, for clients such as Audi, Renault, Dutch Railways (NS) and the Ministry of Health.

• Defined the common front-end stack and coding standards used across projects and teams
• Coached junior and medior developers on their projects and career growth; introduced structure that improved team workflows
• Delivered under hard campaign deadlines — including a multilingual Audi site live within four weeks

All-round web development with a strong UX focus: designing, presenting and building business web applications for clients including PostNL, ING, Rijkswaterstaat, KPN, Ziggo and de Persgroep.

• Grew from front-end specialist to full-stack developer and UX designer across dozens of client projects — from news platforms serving 35M pageviews a month to internal portals
