About Me


I am a software engineer with more than 18 years of experience and an innovative problem solver passionate about leveraging technology for transformative solutions. With a diverse background in software development, in different domains and environments, in both individual contributor and tech leadership roles, I thrive in dynamic environments where I can apply my expertise to drive impactful outcomes. I am committed to continuous learning and driven by a curiosity for emerging trends, I possess a strong track record of delivering results. I like to work aside team members from whom I can learn in order to improve my skills and to whom I can share my knowledge in a deep spirit of collaboration.

I love tackling hard problems that have customer impact, delivering high quality solutions. I'm looking for a senior individual contributor / leadership role where I can take on technical leadership responsibility, and leverage my experience building backend applications, microservices and distributed systems at scale.

Highlights

  • In April 2023 I have joined Powerdale as their Software Development Lead in order to architect the migration to the cloud of their EV Mobility Platform Nexxtmove. I am also managing a small team of software engineers scaling it both at human level and in terms of software development practices. These are exciting times for electric vehicles and electro-mobility and I'm really happy to be able to bring my contribution to that and to a greener future in transportation.

  • Since September 2021 until April 2023, while at Amazon, I worked first in the retail organization to expand Amazon in new marketplaces and geographies and helped with the launch of the amazon.com.be marketplace in Belgium. Then I joined AWS to work on the future of authorization services - in that role I helped my team on their path to launch a new AWS service - Amazon Verified Permissions .

  • While working for SWIFT, for which I started in June 2019, I have developed features for the Alliance Gateway array of products and I've had an extremely important contribution in the process that led my squad adopting proper Agile methodologies practices and that enabled my teammates to work effectively in the context of SWIFT's Agile transformation.

  • In my previous job at Sony Depthsensing Solutions(f.k.a. SoftKinetic), for which I worked between July 2010 and February 2019, I have led and been instrumental in porting and optimizing the 3D sensors drivers and libraries to run on ARM platforms, paving the way for the company's software products to be used inside embedded devices, phones and cars. As part of that effort I have designed and implemented a cross-platform SIMD(Single Instruction Multiple Data) library for low level code optimizations that is still used today as the basis for optimizations across all of Sony Depthsensing Solutions' drivers and middleware.

    That allowed me to easily support within my organization multiple processor architectures in terms of software optimizations. It reduced development and maintenance time and freed engineering resources. The library helped all the teams in the software department achieve quicker and better the targets in terms of performance. It helped my colleagues write better optimized code, allowing them to think more on the algorithmic part of the process rather than on the intricacies and details of the target platform.

    I was the technical lead regarding porting, optimization and multithreading aspects of the Human Tracking Library, a library for multi-user 3D full-body tracking using a depth camera sensor, for the PlayStation 4 console. I designed and implemented the pipelining system of the library in order to achieve optimal performance on the PlayStation 4's hardware. With that architecture in place and the optimizations that it enabled, my team achieved the contractual targets in terms of performance. It was the beginning of the collaboration with Sony, which eventually led to the acquisition by Sony Semiconductor.

    I have led the development of the low level driver and the optimization efforts for the user space driver for a rooftop 3D camera system used in BMW's 2015 series 7 car, which proved to be the start of a very fruitful collaboration concretized with the further development of the system for other BMW models.

    I have also worked on machine learning related libraries and classifier models used for in-cabin gesture recognition and monitoring inside cars, and designed, configured and administered a small cluster solution to run machine learning related task loads. The usage of the cluster reduced the processing time for the model training and parameter tuning from 72 hours to just 8 hours making the model development process much more streamlined and effective.

  • At Freescale(currently NXP), between March 2006 and June 2010, I worked on the CodeWarrior IDE(of Metrowerks fame), developing debuggers and profilers for DSPs and various ARM architecture based processors that Freescale had in its portfolio. As part of that I helped my team deliver successfully through three major product release cycles.

  • At Continental, between November 2004 and February 2006, I developed features related to the ABS(Antilock Brake System) car specific ECUs(Electronic Control Units) that the company was developing at that time.

  • I have extensive knowledge and experience with the C++ programming language, I’m fluent in C, Python, Golang, Java, Rust and Assembly Language. I have knowledge of multiple CPU architectures and experience that spans from working at the lowest level of abstraction - that is close to the CPU using machine code - to the higher level of abstractions - that is software components, frameworks, systems and their interactions.

Interests


My personal interests include:

  • Distributed systems and microservices. As a way forward into my development as a software engineer I'm always trying to learn new things and sharpen my skills about system design, domain driven design, microservices architecture and patterns and how to build performant, resilient and scalable backend services.

  • Machine learning & Deep learning. I have professional experience with and a keen interest in machine learning. I have obtained several ML related online certifications from Coursera and I follow the advancements and the developments in the field. I play sometimes with TensorFlow.

  • High Performance Computing. I have extensive professional knowledge with multithreading, parallelization and SIMD and even if I'm not active in the field nowadays I still make experiments with SIMD optimizations and parallel programs with OpenMP and CUDA in my spare time. I follow the HPC news and I'm really excited about the EuroHPC programme of building petascale and exascale supercomputers across Europe that could be leveraged for scientific and technological advancements.

  • Space exploration. It's an exciting time for space exploration related technologies with private companies like Blue Origin and SpaceX spearheading the progress, with the exciting and unprecedented acceleration and perseverance of Mars endeavors and with the ongoing programs of ESA and NASA that are planning to bring us around or on the Moon again.
