<p>
As a Data & Cloud Engineer at Dataroots, I collaborate with
customers from all sectors to create truly end-to-end data
solutions. This includes not just crafting state-of-the-art models
and analysis platforms, but also building a long term data strategy
and setting up the cloud infrastructure to support it all.
</p>
<p>
Joining a team of five, I started my first project at dataroots in
April of 2023. Our client,
<a href="https://cluepoints.com/">CluePoints</a>, offers a risk and
quality management platform for clinical trials, used among others
by <a href="https://www.pfizer.com/">Pfizer</a> and the <a
href="https://www.fda.gov/">FDA</a>. The goal of our team was to
eliminate bottlenecks and increase flexibility in the trial data
ingestion pipeline. To this end I deployed and benchmarked multiple
datalake components including the Airflow and Prefect workflow
orchestrators, databricks and snowflake data intelligence platforms,
and a combination of dbt, Spark, and custom Python data pipelines.
We were able to reduce the storage requirements by an order of
magnitude and to greatly increase the speed and flexibility of trial
data transformations.
</p>
<p>
On my second and current project, I am collaborating with the
audience data intelligence team of <a
href="https://www.vrt.be/">VRT</a>, the dutch-language public
broadcaster of Belgium. The goal of this project is to integrate
viewership and engagement data from multiple sources into the
company-wide datalake. To best support the existing workflows of the
team, I have developed an Airflow-orchestrated data export task
server for Windows Server. This <a
href="https://fastapi.tiangolo.com/">FastAPI</a> Python server uses
a combination of accessibility automation frameworks and UI machine
vision systems to extract data from GUI-only applications. My
solution eliminates the need for repetitive manual report generation
and allows the creation of rich new dashboards and analyses.
</p>
<p>
I also advised, and helped my teammates in various projects, for
among others, C-Energy, Touring, and Immoscoop. I did this in
particularly through my expertise in machine vision as well as
infrastructure and system administration.

I have developed software in both high and low-level languages
languages: from JavaScript, Python and Kotlin, down to C++, Rust and
Go. Thanks to my computer science master's degree, I have a solid
understanding of the fundamentals of the field, as well as of modern
data science and machine learning techniques.
I believe that the best way to learn is by doing, and I have a track
record of quickly picking up new skills and applying them in
real-world end-to-end projects.
</p>
<p>
Through professional experience, personal projects, and my bachelor
and master's theses, I have gained profound knowledge and the ability
to practically apply deep learning and machine vision techniques for
object detection, classification, and segmentation.
