Uncle IT (Freelance), October 2003 - Present

In 2003 I started my own company and worked on projects for both small and large corporations.

Vlaamse Overheid, May 2023 - Present

As a data analytics team lead for a data fabric project I am in charge of a team that is responsible for data that is related to the railway traffic. We create ORM models from the raw application data and transform the data in DBT. This leads to a clear data structure so that it can be consumed by the business stakeholders. Furthermore we build and validate the necessary Power BI reports in order to get maximum insights in the data. Data Quality is closely monitored and visualised so that it can serve as a starting point for the improvement of the source data. Alignment of the proces, business and functional-technical analysis with the data reports and stakeholder management.

iFlux, October 2017 - May 2023

Shortly after iFlux was founded, I started working on the iFLUX sampling application. In 2021 I expanded my activities at iFLUX and took the lead role in the development of the IoT Sensing application.

iFLUX sampling - Cartridges
Analysis and optimization of the business processes (BPMN) and data modelling (ER modelling) in order to organise the samplers that are used to measure the speed and direction of contaminant spreading underground over a certain period. The application is used to create a visual representation of the installation setup. After a measurement phase, the analysis data is imported (ETL) and used to calculate the ground water and contaminant fluxes. The data reports are build in the platform. For this tool I provided the functional analysis, the database optimization (tuning), the wire-frames, the frontend and backend development as well as the setup of an integration and production environment in order to facilitate the release of new versions and transition towards a continuous integration lifecycle. In order to ensure the usability of the application, I provide the necessary functional support for the employees of the application. The application is written in Python, Django, ORM, JavaScript and D3.js, the data is stored in a PostgreSQL database and accessed with SQL and ORM. Power BI is used for reporting , AWS is used as the backup infrastructure and the code is maintained in a Git repository.

iFLUX Sensing - IoT sensors
Architecture, process, business and functional-technical analysis, management and governance of the data, databases and infrastructure for the processing, Geolocation and visualization of the IoT sensors. The raw data of the different sensors is processed and augmented based on the metadata that is configured in the custom cloud platform (ETL dataflow) that runs on Digital Ocean and AWS. Functional analysis, DevOps (development, server setup, Continuous Integration setup with Git, ...) and management of the Fluxsense application in order to support the business processes. Cost and timing estimations for the API implementation and connections to the webservices of external partners. Analysis and implementation of the NGSI models for the connection to the Smart Cities platform. The data is stored in a PostgreSQL database and accessed though SQL and ORM, the code is maintained in a Git repository, some components are contained in Docker containers, Power BI and Grafana is used for reporting. Datascience and anomaly detection (isolation forest) is handled in Jupyter Notebooks. The data infrastructure (datalake) is based on PostGreSQL, Influx databases and AWS S3 storage.

Vito, November 2019 - Januari 2023

Angular Front-end development for the ‘Natuurwaarde verkenner’ tool. This tool is used to investigate the bio-economical impact of Geographic changes in an urban or rural landscape. Users can draw scenario’s and regions in a graphical Geo-interface. The geographic regions are calculated with the geospatial analysis lib (Turf) and combined with data that is loaded from a GeoServer. The code is maintained in a Git repository, CI/CD with Git and Jenkins.

Python and JavaScript trainings, November 2019 - December 2022

In 2019 I started as a Python and JavaScript instructor for SmartNinja in order to improve my communication and coaching skills. Based on that experience, I wrote a two day course in Jupyter Notebooks for engineers that cover Python, data-science and Git. I used this course as a starting point to train over 75 employees of Comparex and Deme Group.

Vito, May 2017 - April 2018

Creation of wireframes and front-end development for the Atmosys planning tool. This planning tool is a data management interface that allows researchers to configure scenario’s with Geospatial data and calculate the impact based on the air quality models of Vito. Researchers can specify fe. tunnels or low emission zones and verify the impact of the changes on the air quality. The tool is written in JavaScript, Python, Django and the Django Rest Framework, the code is maintained in a Git repository. Setup of the cloud testing infrastructure on AWS virtual servers.

Vito, October 2017 - December 2018

Development and architecture of the front end library that is used to automate the creation of several GIS viewers. The library consists of several ES6 JavaScript components that can be combined to create a GIS viewer. The code is maintained in a Git repository.

Vito, September 2016 - May 2017

Backend API development for the Energy Calculation tool written in Python, Django and the Django Rest Framework. Organisation of the code in a calculation library and a REST interface. Creation of the necessary unit tests to validate the core models. Setup of the cloud testing infrastructure on AWS virtual servers.

Vito, July 2016 - December 2016

Labcyte, January 2016 - 2020

Labcyte is a Silicon Valley based company that moves liquid with sound. The liquid handling machines write all calibration data in HDF-files. In order to interpret the information in a straightforward way, Labcyte asked me to do the business analysis, process analysis and the functional-technical analysis and develop a data model (ER modelling) and visualisation software in order to facilitate the data analysis process. The backend of the visualisation component is written in Django and uses and uses PostgreSQL, Bootstrap, D3.js and JavaScript to visualise the waveforms and analysis data (scatter plots with outlier detection). The code is maintained in a Git repository.
