About Willem

I’m a passionate OutSystems Tech Lead with 8+ years of experience delivering scalable, user-focused solutions for global pharmaceutical clients like Roche. Specializing in Traditional Web, Reactive, and Mobile app development, I excel in designing and migrating complex applications to OutSystems, ensuring seamless scalability and enhanced user experiences.

At Transition Technologies MS, I co-lead a team of seven developers in the EMEA region, delivering a global Knowledge Management platform that empowers Roche employees to organize documentation, share knowledge, and resolve queries efficiently. I spearheaded a critical Salesforce-to-OutSystems migration to address scalability challenges, leveraging SQL, JavaScript, and CSS for seamless data transfers and UX replication. I also designed an intricate role management system for secure user authorizations and built an AI-driven chatbot to boost operational efficiency.

Skilled in Agile methodologies (JIRA, sprint planning), API integrations, and mentoring junior developers, I drive technical excellence in fast-paced environments. My certifications include OutSystems Associate Developer, Google UX Design, and AWS Specialization. Fluent in English, proficient in Portuguese, and native in Afrikaans, I’m eager to lead innovative OutSystems projects.
