Just about me

  • My name is Johan Van Erum and I started my career as an RPG programmer in 1991.

  • I do functional design, requirements- and technical analysis, reverse engineering, programming ( development, testing and maintenance ), application/data migration/conversion and integration. Most commonly I program Rpg ILE, VBA Excel, XML, CL using Rdi, DDS, DDL, CGIDev2 in an Agile/Scrum/Kanban/Jira organized office.​ with modern office 365 tools like Teams.

Working in computing is re-inventing oneself all the time ...

  • In 1991, I started programming RPG on the AS/400, IBM's object based machine. I have been working with IBM and other major service providers to deliver down-to-earth real life business solutions

  • In 1998 I founded Argoo Midrange IS and started as an independent IT professional to offer my expertise and professional analysis, design & programming skills to a variety of companies in the Belgian​ and European marketplace. 

  • Education and keeping up is important, so I just take 2 or 3 courses each year, some practical, some just to keep a feeling with the ever changing "sign o the times". Have a look at some acquired skills.

  • Just mentioning: Data Science with Python, RPA Uipath and Power Automate, PHP/HTML/Perl programming, Drupal/Joomla, Websphere 3.0, Lotus Domino, Java for RPG programmers, Smalltalk, Excel VB script, OO Rational Rose, Facebook/Meta Business Manager
