Bas Maassen is a software engineer with nine years of payments-focused experience, currently building and scaling merchant-facing payments services in Barcelona. He blends hands-on development—contributing to widely used integrations like Adyen’s Magento2 plugin and SFCC cartridges—with engineering management, having founded and grown a team to independently deliver multiple Salesforce integrations. Comfortable across back-end (PHP/Java) and front-end JavaScript work, he has deep domain knowledge of payment workflows, 3D-secure flows, and merchant onboarding. Known for mentoring engineers and translating product needs into reliable, scalable integrations, he pairs technical curiosity with a track record of improving global supportability and developer experience. An interesting thread through his career is moving between implementation, support, and product ownership, which gives him a pragmatic viewpoint on long-term maintainability.
