Developed the website and PWA for Vigixx.com

Full development of the Vigixx website reporting information to users from connected devices (IoT) on the Sigfox network. This information is communicated to users through push notifications. The Progressive Web App (PWA) is developed in Vue.js + Vuetify.js and retrieves push notifications from Firebase. API authentication is using JSON Web Token (JWT). A Vuex store is used. The PWA backend is a Python/Django + Django Rest Framework RESTful API interfacing with the Sigfox API. The corporate website is in pure Python/Django (using templates). This is a microservice application managed via Docker Compose and made up of 4 containers. One of them is an Nginx reverse proxy frontend distributing requests to the application. Database is PostgreSQL. Main challenge: building a reliable push notification system.

Developed the Pepette.co e-shopping website

Developed the full Pepette website made up of a Vue.js frontend for registration and user account, and pure HTML/CSS/Javascript for the corporate website. Backend is entirely in Go (Golang) for the whole site. Backend for the corporate website uses Go's templating system, and backend for registration and account is a RESTful API in Go. Database is PostgreSQL, and no external HTTP server is used (only using Go's built-in HTTP server). Payments and monthly subscriptions are integrated through Stripe. Main challenge: the Vue.js registration process is pretty complex.

Built a High-Performance Lead Generation System

Developped the Fast Track paid RESTful API with a Django Rest Framework backend and a React.js frontend dedicated to delivering leads to customers. In order to add value to the leads data we delivered, I created machine learning tools dedicated to classification based on Python Scikit-Learn and NLTK. Because of critical performance constraints, I developped multiple internal programs in Go (Golang) + Vue.js such as concurrent web scrapers, database fetching APIs, data cleaning tools... All those programs were deployed with Docker and data was stored in multiple PostgreSQL databases.
