Hi there… It’s nice meeting you.

My name is Mikkel Flindt Heisterberg, I live north of Copenhagen, Denmark. My blog is called lekkimworld to indicate this is my “world” (where I capture ideas etc.) and since lekkim is a nickname I have. I hold a bachelor’s degree in Biochemistry and a Master of Science degree in Internet technologies from the University of Copenhagen. Since August 2009 I’ve been married to my lovely wife Mette. We have two children – Milla (a girl) from 2010 and Matheo (a boy) from 2013.


I can be reached in a variety of ways:

  • At my work e-mail at mheisterberg [at] salesforce [dot] com


Positive, competent, out-spoken, frank and customer focused developer with a strong foundation in web development and application development. I’m a strong advocate for object oriented programming and cloud based solutions. Over the last few years I’ve also acted as a solution architect, technical sales and team lead.

I have a knack for being able to communicate and present technically complicated matters in either conference, customer and/or training settings. I always try and work with cutting edge technologies and solutions while keeping an eye on the business value and how to adopt it to actual business needs.

Work history


In October 2018 I changed roles to become part of the pre-sales team as a Cloud Architect to support the Solution Engineers (SE’s) and Account Executives on sales opportunities with all that’s technical in nature. Whenever the area in question falls outside the domain expertise of the Service, Sales, Marketing or Commerce Cloud SE’s we help out. Areas with special focus is the Lightning Platform, Heroku, IoT, integration and security.

In November 2016 I joined Salesforce.com as a Technical Architect in the Customer Success Group (CSG) which is the Professional Services arm of the organization. In CSG we help customers be successful on the Salesforce platform and with Salesforce technology whether that be Sales Cloud, Service Cloud,App Cloud or any other of our many Clouds. We do this by partnering with the customer supplying help, guidance or expertise where needed whether on an ad-hoc basis or on a project basis. I focus on integrations to and from our Platform using the Platform or Heroku as well as Lightning Components and custom development using Lightning.

Part of joining Salesforce is skilling up on the platform and I’m fully certified and have obtained my first 6 Salesforce certifications.


In October of 2007 I joined IntraVision ApS after being self-employed for 8 years. IntraVision is an IBM Premier Business Partner and mostly known for the OnTime Group Calendar product (ontimesuite.com). The products are sold throughout the World using a partner network.

It was a tough decision but I found a good home in IntraVision where I helped shape the technical future of the company brought a lot of technical expertise on the IBM Notes / IBM Domino, IBM Sametime and IBM Connections. Being part of something bigger was both challenging and rewarding. At IntraVision I also took over management of the technical staff that is the developers and the support staff for the off-the-shelf products.

During my time at IntraVision we evolved the main OnTime Group Calendar product from being a product based on a legacy platform to being a fully API enabled product with multiple client front-ends ranging from rich desktop clients to mobile apps based on HTML and for Apple iOS. We also brought the product to Japan where I went 2-3 times a year. Bringing the product to Japan meant many interesting challenges such as supporting multiple calendar systems, the kanji and kana-alphabets and working in a totally different culture.

During my time with IntraVision I was elected an IBM Champion (http://www.ibm.com/developerworks/champion/) for 5 years running, played a major part of the Worldwide community around the IBM Collaboration products and worked closely with IBM on various Design Partner programs to help shape the products.

it-inspiration aps

From 1999 to 2007 I was self-employed with a company called it-inspiration aps. I ran this company with my big brother and an old primary school buddy of mine. it-inspiration served the Danish Notes/Domino customers with consulting services and sold a series of off the shelf products based on Domino and J2EE technologies as well. During my years with it-inspiration aps I developed a great deal using the J2EE stack and we ran a hosted-cloud offering for Danish municipals to help them track occurances of pests such as rats. This solution ran on the JBoss Application Server fronted by Apache with data stored in IBM DB2.


From 1993 to 1999 I was employed by IBM for 6 years working with ERP systems such as SAP, Baan, Oracle, and JD Edwards. Our department was tasked with developing the implementation methodology and education material IBM used/uses for ERP deployment and during my time with IBM the departmental responsibility grew from a Nordic focus to a Worldwide focus.

Writing and articles

Besides the writing I do on this blog (lekkimworld.com) I’ve also written a number of articles for THE VIEW magazine and joined a team for writing a IBM Redbook wiki. I was accepted into the IBM Redbook residency program to write a Redbook wiki on plugin development for Lotus Notes, Lotus Sametime and Lotus Symphony. The writing was from August thru September 2010.

I am proud to be a published writer in THE VIEW magazine:
