about me
I’m passionate about science and technology — whether it’s astronomy, physics, or electronics. I’m always excited to learn something new and push my skills further.
I enjoy building resilient, autonomous systems with simplicity at the core, following the KISS principle.
When I’m not at my computer, you’ll find me running, playing board games, traveling, or diving into a good book.
experiences
With over 10 years of experience, I’ve had the chance to work across diverse fields — from a video game company to an international telecom antifraud firm, and even in optronic R&D.
FraudBuster [October 2020]
Senior software engineer
- Designed and implemented a real-time 4G traffic analysis system capable of processing high-volume network data, using C and DPDK for low-latency packet handling and a Python/Django backend with Celery, and PostgreSQL, enabling scalable deep packet inspection in a telecom environment.
- Designed and implemented a proof of concept ML pipeline to detect fraudulent calls on a GSM network, combining Go-based network capture and audio processing with PyTorch models to generate decision-support indicators for fraud analysts. Evaluated multiple detection approaches, including statistical methods, speech recognition, spectrogram-based classification, and deep learning.
- Joined a newly formed development team following a company merger, contributing to the design of a Mobile Money product by building data collection and transformation tools for mobile money transactions, enabling analysts to efficiently monitor and investigate financial activity.
- Trained and deployed machine learning models to classify scam messages in a Mobile Money fraud context, providing decision-support indicators to assist fraud analysts.
Paternity leave [September 2019]
Round-the-world trip [September 2018]
- Meet and share: improved my interpersonal skills, cross-cultural communication.
- Step out of our comfort zone: this experience enhanced my flexibility and adaptability.
- Develop confidence and organisation: required meticulous planning, budgeting, and logistical management, while building the confidence to navigate unknown territories independently.
- Grow our passion of knowledge: fueled my curiosity and desire to learn, whether it was picking up new languages, understanding local customs, or navigating unfamiliar territories.
Nex Vision [June 2014]
Lead software engineer
- Designed and implemented an embedded video surveillance system for the Airbus A380, enabling real-time display of multiple camera feeds on a single screen, managing video data flow and integration with the Cabin Management System, using GStreamer on a Texas Instruments chipset.
- Designed and architected an embedded gyrostabilized camera system for helicopter applications, combining a custom PCB with an NVIDIA Tegra, real-time FPGA processing, and a C++/Qt/OpenGL software stack, including low-level Linux driver development for motor and camera control.
- Took ownership of software architecture definition, CI implementation, and technical issue resolution, coordinating resources to support multiple development initiatives.
Freelance [May 2012]
Software developer
- Co-created a 2D platformer video game, initially developed in XNA and later migrated to Unity, redesigning the architecture to support the engine transition. Implemented interactive environment systems (water and lava simulation), object-based interactions, and item properties (e.g., wood, stone) to enable gameplay mechanics and puzzle-solving.
- Continued contributing to Unity projects for my previous employer.
So Touch [November 2011]
Lead software engineer
- Designed and implemented an interactive Unity showroom application to showcase search engine capabilities, enabling users to explore travel destinations on a 3D globe. Integrated Kinect, Leap Motion, and 3D display support, including a custom UI system optimized for gesture-based interaction.
- Co-developed and verified iOS projects.
