What I'm looking for

I seek a hands-on role designing and securing enterprise networks, with clear change-control, strong collaboration, and opportunities to lead projects and improve reliability.

I am an accomplished network engineer with deep experience in network design, security solutions, and troubleshooting across enterprise environments.

I have deployed and maintained complex platforms including Cisco, Fortinet, Checkpoint, Meraki and associated management tools, delivering measurable performance and reliability improvements.

I have led and executed multiple projects on time under strict change-control processes, produced HLD/LLD documentation, and collaborated closely with cybersecurity, infrastructure and support teams to build security into systems.

Key achievements include boosting wireless performance by 20%, improving network performance by 30%, achieving 99.9% uptime, and increasing stakeholder satisfaction through effective incident investigation and project delivery.
