|2017 - present||Consultant at College of Computer Studies at Foundation University, Dumaguete, The Philippines.|
|I work 2-3 days a week at Foundation University I consult on Software Development and IoT projects where I teach students while they assist me on software development and IoT projects, and advise capstone and thesis projects. Most projects are run from the Nightowl Technology incubator, which I lead and involve a combination of mobbile and backend software development, electronics and 3D printing..|
|2016 - present||Consultant|
|I specialize in full-stack software development in Python, Angular and Ionic. I furthermore consult on geospatial and scientific data management, analysis and reporting. As my affinity with marine conservation, science and GIS is very strong, I enjoy applying my skills in this area most, but also derive a lot of satisfaction from purely technological challenges. Although my main software development specialty is full-stack web-development in Python and Angular, I am versatile and have experience in Java, C/C++, R, PHP and other languages.|
|2016 - present||Partner at East Solar Works|
|East Solar Works is a solar company that mainly focuses on new applications of solar power. It moved from regular solar power installations to solar water pumping for municipal and rural water supplies. As one of the partners, my main responsibility is implementing ICT solutions, technical support and R&D and optimizing business processes. My previous experience in building IT solutions and as CTO of an IT company come together in this role.|
|2014 - 2016||Science Officer at Marine Conservation Philippines|
|MCP is a non-profit nature conservation organization, funded by its volunteer program. It supports conservation initiatives by the local government and conservation and peoples’ organizations with technical knowledge and trained manpower. My main responsibility was research and monitoring setup and execution, and supervision of interns and volunteers in those activities and coordination with stakeholders. Later on my role shifted more towards techn(olog)ical activities like data management and analysis, GIS and remote sensing activities and IT and spatial data infrastructure management. As part of the scientific monitoring program, I also developed our own data entry (web-)application in AngularJS/Python/PostgreSQL. Since I work as independent consultant, MCP is still one of my clients.|
|2013 - 2014||Lecciones Amazonicas project coordinator at Amazon Fund, Bolivia|
|Coordination of an environmental education project in two consecutive secondary school years, in the Bolivian Amazon. Responsibilities included design and layout (in LateX) of educational material for a field practical and ecology course for secondary schools, and the coordination of the project with schools, teachers, directors, the municipality and local indigenous guides. The educational material was published in a web-portal that I implemented in Drupal.|
|2010 - 2013||Chief Technical Officer at Proigia|
|As a continuation of my work at Elcyon, I co-founded Proigia. It grew into a company with about 7 employees. Proigia still develops a web-based business intelligence platform and services for primary healthcare providers based on their own medical information. The application consists of data extraction, transport, anonymisation, encryption and reporting layers implemented in Python, Java, and PostgreSQL. The reporting front-end for clients was a web-application written in Turbogears and a web-mapping application implemented in OpenLayers/GeoExt/Geoserver/PostGIS. Data extraction, abstraction and interpretation were enormous challenges as data had to be extracted from 7 different IT systems from different companies, and were often very large and badly documented and had grown organically over many years. As CTO is was in charge of the technical strategy and architecture of the company, software development and implementation and IT infrastructure in general.|
|2004 - 2013||Independent contractor in Elcyon.|
|Starting out as a system administrator for various companies, work evolved into website and web-application development, and then on to software developer. The software development became the majority of work and after developing a proof-of-concept web-based GIS, culminated in the founding of Proigia. The last three years all work went into Proigia, with Elcyon taking a background position.|
|2001 - 2004||Various jobs at Wageningen University|
|Including a system administrator at the head office, tutoring a course, development of a website for the Biology study, and development of information material for the health and safety department.|
|2014||SSI Dive Control Specialist at Island Divers, Cambodia.|
|1999 - 2008||MSc in Biology at Wageningen University, specialisation Tropical ecology and a minor in Geographic Information Science|
|1993 - 1999||Secondary school “Stedelijk Gymnasium Apeldoorn”|

I hold an MSc in biology from Wageningen University, The Netherlands. My major thesis was on mangrove ecology in Mozambique and my internship on the mangrove dwelling iguana Ctenosaurus bakeri on Utila, Honduras. My minor thesis was on GIS and was a proof-of-concept on transforming 3D models from CAD programs to 3D formats usable in GIS for 3D visualisation on the web.
But well before uni I already started messing with computers, with one of my earlier accomplishments being screwing up my fathers 386XT computer by installing Windows 95 (it was running windows 3.11) and thus screwing up the harddrive drivers. Although a friend of mine fixed it, my father never trusted me with computers again.
During uni I started to teach myself web-design, system administration, Linux and later on programming. It resulted in different jobs as system administrator, and in me working as an independent contractor setting up and managing servers and networks for a few companies and later also doing programming and database work. It culminated in starting a company together with a friend that offered a business intelligence SAAS platform and consultancy for GP’s and other healthcare practitioners. I was the technical brains of the company. The majority of the work concerned extracting datasets from other applications and translating big unwieldy datasets, into real-life questions and answers for healthcare providers. On the presentation side we had a reporting web-application and a GIS web-application showing geographical representations of data. As a hobby I got interested in electronics and hacking, and became a member of the hackerspace NURDspace. After a few years my company grew to about 7 employees, by which time it was time for me to change my life and I left.
During my university years I did a fair share of travelling in the tropics and me and my wife were itching to get back into nature conservation again. So we packed our bags and left the Netherlands to go travel, volunteer and live abroad. We ran an environmental education project in Bolivia for half a year and volunteered for a marine conservation project in Cambodia. Being divers and ecologists, we wanted to work in marine conservation and found a job as science officer with Marine Conservation Philippines. My role changed from being in charge of the conservation and scientific side of the organization to more technical activities like data analysis and reporting, remote sensing and setting up a web-mapping system. This job was very diverse and ranged from designing scientific research, marine monitoring programs, scientific data collection, management and analysis (PostgreSQL and R), setting up the spatial data infrastructure and doing all mapping and remote sensing activities, supervising interns and volunteers, consulting local government and people’s organizations in their marine conservation activities and much more. On the technical side I also managed the IT infrastructure and developed and maintained a scientific data entry and management application.
In 2016 I decided that although there a there a lot of interesting projects I worked on at MCP, my skills were best used by using technology to support conservation organizations. I furthermore missed software development and more technological work so decided to become a freelance consultant. I have always enjoyed wrestling with and analyzing large amounts of data (geographic and otherwise) and visualizing it in user-friendly ways (usually web-based). From a scientific point of view, that is where I think I can be of most value. I also enjoy helping businesses become more effective/efficient by implementing technological solutions. So when I was asked by East Solar Works to become a partner and aid them with making their solar water pumping business more efficient by implementing remote monitoring and management software and optimizing their business processes, I accepted. Since the work is sporadic, it still allows me to operate as freelance consultant. And what started to be voluntary activities at Foundation University in Dumaguete in supporting a newly established hackerspace, quickly turned into an offer to be employed at the College of Computer Studies as a consultant for two days a week. They asked me to help start projects and support the establishment of a hackerspace/makerspace where we build “cool” technology stuff, preferably for environmentally or socially relevant projects. Most activities are extra-curricular for the students, but I also aid students with their thesis projects, and advise the college dean on research and education strategy. Recently we are trying to lift this initiative to a higher level with tighter cooperation with the industry and looking for grants to enable this. This job allows me to work more closely with young and enthusiastic Filipino’s and to finally give voice to my long-lived desire to show kids from all walks of life that with access to a computer and internet you can make a living, no matter what your education or upbringing. According to other people I can be quite hyperactive and passionate in my opinions (I still don’t believe them though). I love to try and learn new things and am quick to understand problems and new theory. I have a very analytical mind. I love solving technical problems much more than managing and having meetings. The more difficult the problem, the more I am committed in solving it.
