Over Walter

I am a freelance OutSystems consultant with 17 years of ICT experience, including seven years as an external consultant at the European Investment Bank. Since 2013, I have combined OutSystems development with architectural responsibilities, helping teams turn business requirements into practical, maintainable solutions. My experience covers OutSystems Traditional and Reactive, SQL, C#/.NET, REST/SOAP integrations, cloud migration and identity management. I design reusable components, document technical decisions and work with enterprise architects to agree solutions and follow them through implementation. I also support developers through technical reviews, mentoring and workshops. One recent example is a shared email service that I recommended using Microsoft Graph. Built for OutSystems and other applications, the solution supports multiple senders, bulk email, queues, error handling and configurable retries. I hold the OutSystems Architecture Specialist (O11) specialisation and an MBA in Artificial Intelligence. I am looking for hands-on architecture assignments where I can help modernise applications, solve integration challenges and support reliable delivery. I am based in Luxembourg and willing to work onsite in the Netherlands as required. I work in English and do not currently speak Dutch. My start date would need to be agreed.
