Now at Alstom
I like it when software makes something real move: a train, a car, a robot.
It started with classes prépa and a dual degree in Toulon: mechatronic systems and robotics on one side, artificial intelligence on the other. In Bangkok, I worked on energy management for solar electric vehicles on a TI F28335 board. At Renault, I turned weeks of manual Excel work into Python tools that run in 30 seconds. Today, at Alstom in Pittsburgh, I build software for safety-critical railway signaling, and my work is moving more and more toward data, AI and full-stack development.

18-month VIE contract, from November 1, 2025 to April 30, 2027.
I build the tools that turn raw signaling logs into data engineers can use: a C# parser, compact files and Python dashboards. My work is moving more and more toward data, AI and full-stack software.
Certified during the VIE: DataCamp certification in Polars and Parquet.
Internal tools under NDA: no screenshots or source code can be shown.
Final-year internshipMar â Aug 2025 · 6 months
Renault Group · Ampere Software Technology · Team S53, Power Activation & Distribution
At Ampere, Renaultâs software company, I joined the team that designs how power is distributed and switched in the . Engineers spent days copying data between the , calibrations and screens. I built eight Python tools that do it for them.
How every tool works
Packaged as .exe files, versioned on GitLab and shared on SharePoint.
Select a tool to see what it replaced.
Generates DDT2000 diagnostic screens in XML straight from the electrical data, for the Distribution, Shutdown and OEM cases.
Before5 to 7 days per screen, built by hand
AfterAbout 1 second per screen, plus a quick review
Builds the full set of 499 Recorder screens automatically, with a uniform layout.
Beforeâ 16.6 hours of manual setup
AfterUnder 10 seconds, whatever the quantity
One desktop app that brings the tools together so engineers who do not code can use them, with guides and clear error messages.
BeforeScattered scripts, Python required
AfterOne entry point, shipped as an .exe
Cross-checks wire protection calibrations between the electrical distribution scheme and the APSW data, and logs every change.
BeforeSeveral hours per file, copy and paste
AfterUnder 1 minute, then a short review
Extracts and structures the supplier calibration parameters of the SmartMOS power switches for the other tools.
Beforeâ 7 minutes per triplet
After10 triplets in about 1 minute
Validates the electrical distribution scheme with six rule sets: currents, ASIL levels, MBSE energy flow and more, in one consolidated report.
Beforeâ 16 hours, two working days
Afterâ 4 hours, review included
Cross-checks about 540 AUTOSAR calibrations per PIU and per function, and ranks the discrepancies to fix first.
Beforeâ 27.5 hours per campaign
Afterâ 48 minutes, review included
Web app to choose the right SmartMOS: current profile, ±10 % tolerance band and software curves on one interactive chart.
Beforeâ 55 minutes per profile, 3 to 4 separate charts
Afterâ 3.5 minutes, one overlay with PNG and CSV export
âThrough his rigor, his knowledge, his ability to communicate and his critical thinking, Enzo showed every day that he has everything it takes for a great engineering career. All the tools he developed are used in the teamâs internal process.â
The tools and their outputs are confidential, so no screenshots here. Figures come from my internship report.
Six projects, one key result each. Open âHow I did itâ for the details, or go straight to the report or the code.
Simulation
With Ewen Guivarch
Stop a car at 100 km/h as fast as possible without locking the wheels.
4ABS controllers designed and compared
Modelled the wheel and vehicle dynamics in MATLAB/Simulink, then designed and compared four ABS controllers (continuous PI, discrete PI, on-off and an improved on-off) and added EBD front/rear brake distribution.
The improved on-off controller gave the shortest stopping distances, with wheel slip held close to the optimal 0.2. EBD prevented the rear wheels from locking early.
Data & AI
Solo project
Tell spam apart from normal text messages.
98.8%validation accuracy
Built a TensorFlow/Keras pipeline: text vectorization, word embeddings, two bidirectional LSTM layers, dropout and a tf.data input pipeline.
About 98.8% accuracy on the validation set, and all freeCodeCamp tests passed.
Robotics
With Camille Berta
Let a TurtleBot move through a cluttered room on its own.
2environments: Gazebo and the real robot
Programmed a ROS state machine in two stages: first reacting to bumper contacts (back up, turn, carry on), then processing LiDAR scans to anticipate obstacles before touching them.
The robot avoided obstacles both in simulation and in real conditions. One limit to improve: it always turned the same way.
Data & AI
Solo project
Suggest books similar to one a reader already liked.
1.1Mratings turned into recommendations
Filtered 1.1 million ratings down to active users and popular books, built a sparse book-by-user matrix and a k-nearest-neighbours model with cosine distance in scikit-learn.
Returns the five closest books for any title in the dataset, and passes the freeCodeCamp test.
Data & AI
Solo project
Beat four scripted opponents, with over 60% wins against each.
99%best win rate, 4 of 4 opponents beaten
Wrote a multi-level Markov predictor that reads the opponentâs last 4, 3 and 2 moves, falls back on move frequencies and corrects itself when its win rate drops.
99%, 78%, 65% and 63% win rates over 1,000 games against each opponent.
Data & AI
Solo project
Classify photos as cats or dogs.
72%of test images correctly classified
Trained a convolutional neural network in TensorFlow/Keras, fed by image data generators, for 15 epochs.
72% of the test images correctly classified, enough to pass the freeCodeCamp challenge.
Research internshipApril â August 2024
Thai-French Innovation Institute (TFII), King Mongkutâs University of Technology North Bangkok
I worked on the energy management of a solar electric vehicle: a control system that makes the best use of variable solar power while keeping the vehicle stable.
Everything ran on a Texas Instruments TMS320F28335 board: generating PWM signals, reading voltage and current sensors through the ADC, and driving buck and boost converters.
Ten sessions in three phases. Each one opens its PDF.
Mr. Enzo Cherif has shown exceptional dedication and skill throughout the internship, particularly in the areas of problem-solving and adaptability.

LaTeXReports and lab guidesWhat my internship supervisor and two of my teachers wrote about me.
Enzoâs internship at TFII went extremely well. He successfully completed all the research tasks assigned during the internship period. His commitment and technical skills even led him to take on a teaching role for a small group of Thai students. Beyond his professional achievements, Enzo built genuine bonds with our team. He integrated into a different culture with deep respect and humility, becoming a truly appreciated member of our institute.
I had the pleasure of teaching Enzo as part of management courses at SeaTech. He quickly stood out for his seriousness, his ability to bridge technical and organizational aspects, and his consistently professional attitude. Curious, rigorous, and deeply engaged, Enzo also demonstrates a rare level of human maturity, making him a trustworthy student and a very promising future engineer.
Ghizlane KinaniManagement professor, SeaTech, Université de Toulon
Enzo has been my student for two years, and I can confidently vouch for his dedication and strong work ethic. He enjoys challenges and consistently strives to achieve his goals through determination and perseverance. His work is of high quality, usually submitted on time, and often includes a surprising or creative touch. Enzo follows through on his ideas, and I am certain he will succeed in all his future endeavors.
