In November 1997 i finally started my own company. Since then i am for hire.

Picking up where I left off a few years ago: further developing and improving a ruby-on-rails based GIS application for pipeline management.- upgrading three rails websites from rails 2.3.8 to rails 3.2.x/bootstrap/jquery/ruby 1.9.3 - again upgrading to rails 4.x/ruby 2.15 and sharing more code- deploying on windows/oraclepostgis servers at our clients site and linux for saas- adding complete test coverage using rspec/cucumber/jasmine- replaced the… Show more Picking up where I left off a few years ago: further developing and improving a ruby-on-rails based GIS application for pipeline management.- upgrading three rails websites from rails 2.3.8 to rails 3.2.x/bootstrap/jquery/ruby 1.9.3 - again upgrading to rails 4.x/ruby 2.15 and sharing more code- deploying on windows/oraclepostgis servers at our clients site and linux for saas- adding complete test coverage using rspec/cucumber/jasmine- replaced the previously used geographic viewer (Star Next7)- migrated from Oracle to using open source technology (postgres/geoserver/leaflet)- built a SAAS platform to manage KLIP/KLIM plan-requests - built a SAAS platform to follow-up digitalisation work at Telenet for DIGIFULL project (AQL)- built several smaller websites to follow-up inspections our company or subcontractors perform (e.g. CP inspection or visiting land-owners)- introduced better data-management tools for our GIS: keeping original geometries (RD/LAmbert), better versioning and batch management (visual comparisons after import/before activation), better import of Kadaster NL/BE data (with visual/administrative inspection of differences) Show less

* build an API for their Rails based participation platform * support/extend the backend of the participation platform

Developing a super intuitive search-engine aimed at pharmaceutical companies. It will connect to different data-sources and hopefully find/discover relevant information quickly.Keywords: rdf, sparql, linked data, ruby-on-rails, coffeescript, rspec/jasmine/cucumber

Aaltra designed a very clean site for their client. The goal of the site was to offer visitors a free taste of what the full site could offer. So therefore the client requested, for safety/security, that their full API would be hidden by a proxy server, and this proxy server needed to be implemented in ruby on rails. I used rails api, grape and swagger to implement a clean API.

- designed and implemented CORBA-like messaging solution based on BEA MessageQ- designed and implemented automatic reporting services. Data was gathered from Oracle and converted to xml, split up for performance reasons, rendered using office, and combined again. We used a workflow system, loadbalancing, relying on messaging to distribute jobs, over several servers.Electronic documents were put either held for manual approval, or automatically delivered.Mainly c++ development on… Show more - designed and implemented CORBA-like messaging solution based on BEA MessageQ- designed and implemented automatic reporting services.
