Software Engineer

Opti-MixLille, France

Worked on web extraction workflows, data-driven optimization tools, reporting and client data pipelines for retail-related use cases.

Overview

At Opti-Mix, I worked on several technical projects related to data extraction, price analysis and client delivery workflows. This period was foundational in my career because I worked on both development and operational topics: building new scripts, maintaining existing ones, loading and exporting data, testing websites manually and interacting with client needs.

Among the projects I worked on was xlbscrapper, a Node.js web extraction tool designed to navigate sites efficiently and in parallel. I also contributed to chainreporter, a desktop application used to analyze CSV files and produce interactive reports for quality control before delivery. Another project was xlbwebchangecapturer, a Node.js script used to generate organized screenshots from a predefined list of URLs in order to track design and content changes over time.

This role taught me a lot about handling real-world data workflows and maintaining reliability in systems that interact with external sources.
