Back to original languageAbout Régis
Technologies change, concepts remain.I believe in creating sustainable applications, designed from a complete understanding of user needs. From this perspective, an application embodies the simplest possible solution to the architectural and algorithmic problems raised by their concrete needs.
Proposed Missions
Specifications.I interact directly with the business to capture needs as faithfully as possible, closest to the value creation in your company. Potential evolutions of needs are discussed from the outset to find the right degree of solution scalability.
Architecture.One or more architectures are proposed so that you can choose the one that best suits your constraints of security, budget, existing infrastructure, data retention, as well as the expected service level of the solution.
Implementation.I will accompany you through the implementation of the chosen solution in languages such as python, Scala, go, or rust.
About me
I hold a master's degree in financial mathematics (formerly DEA El Karoui) and worked as a quantitative developer at JPMorgan in London for two years. I have since assisted several companies on Malt as a developer.
I have been using the Python programming language since 2014, particularly its numerical and statistical computing libraries (numpy, scipy, pandas), sometimes for parallel computing (numba, CUDA). I use the Django web framework (for creating APIs, I prefer FastAPI), most often coupled with a relational database (Postgres).
Front-end is not my specialty, but I have used modern Javascript frameworks such as Vue or React.
I enjoyed the following books:
- Structure and Interpretation of Computer Programs
- Designing Data-Intensive Applications
- The Art of Unix Programming
