Hoi, my name is Lex, and I believe great user experiences start with solid foundations.
DynatraceGraz, Austria
At Dynatrace, I work on the customer billing portal, helping customers understand their usage, manage costs, and gain insights into their environment. Shortly after joining, I identified a part of the application that had accumulated years of technical debt during a framework migration and proposed a redesign to stakeholders. After gaining support, I rearchitected the underlying navigation and routing system, eliminating issues that affected users throughout the portal while making the codebase significantly easier to evolve. The experience reinforced my belief that great user experiences start with solid architectural foundations.
Jibe CompanyEindhoven, The Netherlands
At Jibe, I worked on projects across React, Vue, Django, and ASP.NET. Between client projects, I took the initiative to redesign and rebuild a tool used by field technicians to communicate with display systems over a custom byte protocol. What started as a request for workflow support quickly revealed deeper usability issues, so I redesigned the application from the ground up and developed the C# backend responsible for serial communication. By introducing workflow automation, search, grouping, contextual help, and multi-device support, I transformed what felt like an expert-only tool into something far more approachable.
SupertaskUden, The Netherlands
Wanting to experience entrepreneurship firsthand, I co-founded a software company with two friends. Beyond building software, I enjoyed working directly with clients to understand their challenges and shape solutions together. The projects ranged from optimizing reporting software for Mars, reducing report generation times from over thirty minutes to around one minute, to delivering production-ready applications under extremely tight deadlines. Depending on the project, I took on everything from architecture and implementation to client communication and cross-team collaboration.
KorsitEindhoven, The Netherlands
As an intern at Korsit, I worked on the localization system of a large Vue-based webshop. The existing solution lacked support for region-specific translations, and my focus was on introducing that flexibility without creating additional maintenance overhead. It was an early lesson in improving established systems while preserving backwards compatibility.
Coffee ITUtrecht, The Netherlands
I joined Coffee IT expecting to work primarily with React, but quickly developed an appreciation for Angular and Ionic while building mobile applications. After delivering an application from scratch, I proposed introducing React Native as an alternative for future hybrid apps. Following a successful pilot project, where I helped guide the team, establish best practices, and mentor developers new to the framework, React Native became the company's preferred choice for future hybrid applications.
