Harald Kastelijn is eager to learn and seeks challenges for personal development. His fascination with technology and programming started at an early age.
This helped him earn a bachelor’s degree in computer science and in 1998 he started his career as SAP ABAP developer. He quickly discovered his interest in application integration and pursuit this interest working for multinationals such as Shell, Unilever and Heineken.
In 2005 he took his next career step and joined Philips. Over the next 10 years he learned about Integration and Solution Architecture – but also about the inner workings and challenges found in complex organizations.
In 2015 he left Philips for a new challenge, starting an IT consulting firm. Recognizing the increasing importance of Integration he founded Hashtag Integration. Its mission is to help organizations enable Integration and achieve Digital Transformation.
His believe to commit to the success of clients, beyond the scope of the assignment, is the guiding principle for Hashtag Integration today.
Hashtag Integration was assigned several projects. One of the more challenging projects was the migration of a mission critical application cluster from a 3rd party to NS. The objective was to map the cluster’s IT functions to existing NS IT services and identify gaps. This was a challenging task given the diversity of stakeholders consisting of NS, the 3rd party and multiple IT partners. I commend Hashtag Integration for delivering the best outcome on a job well done.
Hashtag Integration joined JDE when we were on a transformation journey after a large Business merger and since then has been instrumental in driving our Integration road map & strategy. I value their structured approach, stakeholder management skills, solution-oriented thinking and results driven approach. Hashtag Integration strives for the optimal solution, challenges the status quo and takes the ownership in getting the job well done. I would highly recommend Hashtag Integration.
