About Clemence

Front-end developer (ReactJS/Typescript) with 5 years of experience, including 1 year in fullstack (NestJS/Prisma).

Available for front-end development, I can participate in reflections and decisions related to the business around product creation. My experience and preferences lead me towards products around data management and process facilitation. Unlocking insights and decision support from raw data is a most motivating challenge!

I like efficient and rigorous work, so I prefer to work from mockups. My code is tested and organized, and I'm an advocate for breaking down large projects into small daily steps.

    • Research and development includes:
    - data scraping in python and go (several sources and formats for the data);
    - neural language processing tests, in particular with the spacy library for various uses: NER to identify the signatory companies in the texts, TF-IDF to thematize each agreement relative to the global corpus and clustering to identify groups of companies;
    - tests on Neo4J to represent the connection within the data set and make suggestions/recommendations to users based on searches made by users with the same profiles;
    - tests on elasticsearch for textual research.
