Over mij
A seasoned IBMi Developer bridging the gap between the reliability of the AS400 and the power of the modern AI era. With over 24 years of experience—ranging from System/36 to modern Free-Format RPG—I specialize in transforming 'green screen' legacy environments into high-performance, web-enabled systems. I don't just maintain systems; I modernize them. I am a firm believer that the AS400 belongs in today's tech stack. I’ve personally pioneered REST API integrations to connect IBM i with external ecosystems and developed custom solutions for EBCDIC to UTF-8 conversion.
