Maruis Marais’s Experience
-
Senior Developer
ING (NZ) Limited
(Public Company; 1001-5000 employees; Insurance industry)
December 2007 — Present (1 year 8 months)
My duties at ING Life consist of the conversion of their insurance quoting software from Delphi to C#. We utilized Castle Active Record (NHibernate) as an object relational mapping layer (data access) and then build the business rules into the rich domain model. Within this rich domain model I’ve used the following design patterns, the Specification pattern to select the correct benefit rate, the Factory Method in several places to create object hierarchies, and the Strategy pattern to encapsulate the algorithm. We also employed Single Table Inheritance (STI) to represent the benefit inheritance hierarchy of classes as a single table. For the validation and correctness of input data, we leveraged the validation support build into Castle Active Record.

Senior Ruby on Rails Developer
classifieds.co.nz
(Privately Held; Myself Only; Internet industry)
December 2007 — Present (1 year 8 months)
Site: http://www.classifieds.co.nz
My involvement in http://www.classifieds.co.nz spanned the complete lifecycle of the web site. I only work on the project in my spare time. From a design perspective, the only elements on the site left from the original design template are the header and footer. The site uses attachment_fu with RMagick to handle image manipulation and uploads to amazon S3, where the images are hosted. Searching is handled with acts_as_ferret and currently I'm working on caching to improve performance.
The plan is to integrate a lot more Ajax into the application, but firstly I want to drive out most of the functionality and then layer the Ajax elements. This will allow me to degrade the functionality nicely when JavaScript is disabled. -

03/12/07 Meg Tillett of Sysmex NZ Ltd - R&D Operations Manager
Marius fitted into our team easily and was able to be productive in a very short time. He was willing to offer assistance to others, make suggestions and generally made a valuable contribution to our team. His work ethic, productivity and technical ability is excellent. He worked well with people in the team, both those who were his peers and those more junior or less experienced. I'd have no hesitation in recommending him to any other organisation as a contractor or in a more permanent role. -
