From network operations in Lahore to production engineering in Rennes
I am an L2 Network Engineer based in Rennes, with more than three years of experience across campus fabrics, data-center operations, and cloud edge connectivity.
At Audi Rennes I design and operate Cisco Nexus topologies, automate security policy, and lead data-center migration work with zero downtime for customer-facing services. I also run SolarWinds-based monitoring and disaster-recovery planning, and I mentor junior engineers on the team.
At Netplus Rennes I worked on AWS Wavelength for mobile edge applications, multi-VPC environments for SaaS products, and after-hours on-call — resolving the large majority of critical incidents inside the SLA.
Before moving to France I was a Network Operations Specialist at Systems Limited in Lahore, looking after routers and switches for a 10,000+ user estate and standardizing the procedures the team used every day.
I hold CompTIA+, CCNA Routing and Switching, and EC-Council Certified Network Defender credentials, and I have written publicly on advanced network security protocols. I am motivated by networks that stay up, stay secure, and stay understandable when something breaks.
