Data Science developer in Japan (UTC+9)

### Expertise I have a scientific background with a focus on Physics & Chemistry (bachelor level), and Neurosciences (master level) before becoming a Python Developer and Data Scientist. Here are some projects I developed for my customers: * created several custom ChatGPT chatbots to allow users to ask questions about customers' own documents (PDF, website, text, Excel). * used diffusion models like Stable Diffusion or DALL-E to create new images from text instructions or edit existing images (change background, add characters, etc.). * fine-tuned a deep learning model to classify comments automatically as positive or negative. * trained a deep learning model to transcribe handwritten text into excel * gathered data from websites and generated graphs to display information relevant to the customers. * created web applications to allow customers to upload data, process it, and visualize it. ### Technical Stack **Data gathering :** * scraping (beautifulsoup, selenium, scrapy, splash), use of tools facilitating scraping like [zyte.com](http://zyte.com/). Scraped sites: Google, Fnac, Cultura, Amazon etc. * various API calls: google sheet, pipedrive, pubmed etc. **Data processing :** * reading files in different formats: json, csv, text, excel * data cleaning and processing with pandas and numpy * data storage in databases: mongoDB, DocumentDB, PostgreSQL **Data visualization** * Python visualization libraries: matplotlib, seaborn, plotly * dashboard generation with PowerBI (Microsoft) and QuickSight (AWS) **Data analysis, prediction and classification** * use of sklearn and statsmodels to analyze the data * training of pre-trained deep-learning model with tensorflow and pytorch to do sentiment classification (NLP) * use of chatgpt to do Question Answering with a vector database (FAISS, pinecone etc.) **Creation of containerized application (docker)** * creation of API with Flask, FastAPI * application creation with streamlit and Flask, deployment on AWS (lambda, API gateway, S3, SQS) **CI/CD**: gitlab, serverless framework
