Hi, I'm
Farel Tchatchouang,
but you can call me Rosvelt.
I'm a software and AI engineer and trainer, and I build applications and AI systems all the way to production.
Rigorous and a bit of a perfectionist, I'm passionate about reliable, well-thought-out and useful products.
From fullstack development to senior IT consulting, through AI and training.
Sessions I deliver for companies and training centers, from application acceptance testing to generative AI.

Full preparation of course material and delivery of the sessions.
« Merci à Rosvelt qui s'implique totalement et qui a de très bonne connaissance »
« Une formation intéressante et riche en informations pertinentes, permettant de (re)découvrir des outils tels que SoapUI, Postman, VS Code ou GitHub dans le cadre du développement d'un projet basé sur le framework Django REST. »
