Micro-seismicity monitoring networks are compulsory for industrial achievement of geothermal projects, notably to ensure the absence of damage on third parties. Those networks are characterized by the lowest magnitude at which a seismic event can be triggered: the magnitude of completeness. In the study I made, a method was tested, based on computer simulations of seismic event by calculating the discrete wavenumber through the code of AXITRA. This code is usually used for remote earthquakes. The simulation is based on a 1D geological model, a station network, and a seismic event for which we can determine the source mechanism. A simulation was led on a well-known area for geothermal energy in Alsace, where occurred an also well-known real seismic event, and tried to reproduce this event numerically to evaluate the code of AXITRA. After quality evaluation of seismograms and spectrograms, it was then tested on another area for which there is so few feedbacks. The results were compared with an…

Oxand is a french company. Its value proposition centres on construction of indicators from data. It aims to make life easier for decision-makers, to help save money, to automate the decision-making process, and ensure a better risk management. Oxand Simeo™️ is the tool realizing this ambition. This solution already went to market and reached a great success. Within the frame of the refactoring and further improvement of Simeo™️, I was asked to enforce alignment between product owner on one side, and developers on the other side. It implied resorting to the fundamentals concepts and tools of Domain-Driven Design (DDD). I work on facilitation of the meetings and writing the preparatory documentation. This preliminary documents included : the ubiquitous language the domain modeling with entities, aggregates, or business contexts, gathering the use cases and expectations of the product owner user stories

Making a comparative analysis of multiple Optical Character Recognition (OCR) algorithms to read license plate of vehicles from all countries using the Green Card Insurance System For example, this licence plate from Japan is fortunately not related to the Green Card Insurance System. It was difficult enough to deal with Ukrainian vanity plates. Do no hesitate to ask for the fun facts I learned about identification plates.

Egis is an international group originated from France, dedicated to Engineering in numerous business lines such as civil, hydraulic, or railways. In my case, I have worked for Egis Rail. The filial developed internally a software dedicated to network provisioning of mass transit systems and optimizing commercial operations : Simalim ™. The source-code was originally written in a programming language who lost market momentum. In order to keep the software aligned with the state of the art in the software industry, it was decided to proceed to a migration to the C#/.NET technical platform. The software has remained a desktop…

Data New Road is a joint-venture between APRR and Amiltone. The enterprise is dedicated to develop data science solutions, specialized on problematics implying vehicles and road networks. My mission included : Taking notice of previous work on the same topic Analysis of the goals and hopes of the final customer Gathering and organizing upload in database of raw data Definition of first refining of the data Testing multiple statistic regression methods Exposing results and limits Debating with customer about the actions to take to make the product achievable in the future

As a software engineer, I worked on different topics. SNCF New Access Control Gate Its main added-value is the fight against freeloaders. It detects any fraudulent walk-through and consequently blocks the gate safely. It also counts the frauds at each gate of each station and allows the rail operators to shift the effort of ticket inspection accordingly. This new generation of access control gate was aimed to serve on the Parisian mass transit network. I worked on the development of the supervision application layer, controlling the gates remotely. The supervision layer was made with the integrated solution PcVue, which brought me to code some stuff in SCADA Basic. Configuration subsystem Conduent has a complete home-made Business Framework, which is used to code a complete ticketing…

Électricité de France is a leader on the European energy market. It had a Financial Management software. This software was written in Python. I performed evolutionary maintenance on this tool. We used Eclipse as IDE. The Human-Machine Interface was designed through PyQt. Orange is a french telecom company. It had a software dedicated to activation of internet services. I performed evolutionary maintenance on this tool. This software was written in Java, using the Spring framework. Selenium was used for tests. We used Eclipse as IDE,…

A significant part of my engineer course focused on data processing methodologies and solving inverse problems (time-frequency analysis, wavelet analysis, statistical learning, …). This is the part I use on a daily basis in my professional work. This master was also the occasion to reap general knowledge in Geophysics (seismology, seismic, geomagnetism, rock physics, geodesy, …)

This “Classe Préparatoire” is a preliminary training for the engineering school in France. The student will be then recruited by French engineering schools by competitive examinations or by written applications. Teachings : – Mathematics – Physics (Optics, Electromagnetism, Mechanics, Thermodynamics…) – Chemistry – Electrical Engineering – Mechanical Engineering (Computer Modelling…)

During this training was studied several aspect of electrotechnics : – Electrical motors (direct current motors, alternative current motor, etc…) – transformers – power electronics – power network stability – industrial automatic devices

Within the frame of an internship, I and another student performed measurements of gravity at the vertical of the Enhanced Geothermal System reservoir of Soultz-sous-Forêt. Those measurements, performed two months long every year, allow to observe the influence of hydraulic injection on the local gravity.

Birdz is an innovative company. It designs and develops hardware, software and networking products. Collaborators dedicate to environmental issues. The corporation deploys IoT networks. The enterprise also collects, integrates, and analyzes data of IoT systems. I have worked on an anti-corruption layer of the information system. This ACL is set apart to encode and encode radio frames emitted by IoT devices, and to integrate them in the information system. Birdz developed a specific tool to ease the work of engineers. This tool helps to program the encoding and decoding of radio frames. Engineers interfaces with the tool through a tailored Domain Specific Language. This DSL is a declarative language inspired by OCaml. The tool is run by Google Cloud Platform. Rebuilding knowledge of numerous IoT devices is a…
