Introduction
I am a Data & Machine Learning Engineer with 7 years of experience developing the backend of AI applications and data pipelines. I work autonomously across the full lifecycle, from data collection and large‑scale processing to modeling, deployment, and monitoring, and I enjoy taking ownership of technical choices around Big Data frameworks and architectures. I have solid understanding of statistical models, associated with Big Data Analytics , Cloud services and ML pipelines. I’m passionate about MLOps, DataOps, and DevOps topics, with a deep interest in technology, automation, and building reliable production systems. With a background in statistics, I have a strong command of machine learning, deep learning, and data analysis methods. I've worked in several sectors like CRM, Media, Fintech, Cyber security, Marketing, recrutement and psychology , and led several machine/deep learning projects. My main objective is to grow in a stimulating, fast‑paced environment, working on interesting and impactful projects alongside data scientists, analysts, engineers, and cross‑functional teams, where I can create real value and contribute to innovation. github link: https://github.com/Dorsaf-Sdiri
