What I'm looking for

I seek a hands-on IT infrastructure or management role where I can lead deployments, improve security, mentor teams, and implement scalable solutions in a collaborative, growth-oriented company.

I am an IT manager with hands-on experience designing and implementing company-wide IT strategy for retail environments. I led infrastructure deployments across stores, warehouses, and factories, selecting equipment and ensuring projects met deadlines and budgets.

I maintained and supported a wide range of hardware and services, including servers, firewalls, VPNs, Wi‑Fi, POS systems, printers, cameras, IoT devices and Zebra PDAs, while optimizing tool interconnectivity. I also performed regular technological watch to keep infrastructures current.

I ensured IT security and regulatory compliance by implementing cybersecurity tools, training users, and aligning practices with GDPR, ISO 9000 and CNIL recommendations. I negotiated and managed contracts with external providers to deliver reliable service and cost-effective solutions.

Earlier roles in field support and systems & networks gave me strong incident diagnosis, server and network maintenance, and client-facing training experience. I am proactive about improving processes and providing continuous technical support to end users.
