Experience

VS Consulting Group

☀️ 09/2023 - 11/2025
👨‍💻 Python & Javascript Developer
🚩 Belgium, on-site

In this role, I took on the challenge of reviving and transforming a large legacy integration system connecting Odoo with several automated third-party warehouses through their APIs. The project was a living ecosystem: seasonal peaks with thousands of orders, complex purchasing flows, real-time stock updates, and automated warehouse operations. My responsibility was not only to fix and stabilize this foundation but to turn it into a predictable, scalable, and future-proof platform. I introduced a full development lifecycle, built simulation tools for API interactions, automated tests, and added new features that removed long-standing bottlenecks. As a result, the client gained the ability to process significantly higher order volumes without growing the team and to replicate these operational pipelines across new business domains.

Beyond the core work, I also designed internal tools for producing high-quality presentations for top-tier enterprise clients accustomed to presidential-level service.
