About

I'm a Cisco VC & Infrastructure Engineer with 4+ years of hands-on experience managing mission-critical collaboration infrastructure for a global multinational banking environment. My work sits at the intersection of enterprise video conferencing, network infrastructure, and real-time media quality and I thrive in high-stakes environments where communication systems simply cannot fail. What I do best: At HCL Technologies, I supported one of the most demanding VC/AV environments in the financial sector managing Cisco Telepresence, Webex, RoomOS, VIMT, and Microsoft Teams Rooms (MTR) deployments across AMRS, EMEA, and APAC. My work spanned everything from deep-dive SIP/RTP packet analysis and QoS validation to coordinating large-scale endpoint migrations and recovering data center infrastructure during critical outages. Some highlights from my journey: 🔹 Led the migration of 2,000+ Cisco endpoints from on-premises CE firmware to RoomOS 11 (Cloud), enforcing unified security standards across the global fleet. 🔹 Reduced team MTTR by 25% by building 15+ technical runbooks and standardized troubleshooting protocols. 🔹 Restored critical infrastructure during high-impact data center failures, including ROMmon switch recovery and ESXi upgrade incidents. 🔹 Delivered training sessions and case studies to fellow L2 engineers, improving team proficiency and reducing escalation rates. 🔹 Recognized with a Client Certificate of Appreciation for maintaining service stability during critical enterprise outages. My technical toolkit: Cisco Telepresence | RoomOS | Webex Control Hub | CUCM | Unity | Expressway-C | VIMT & MTR | CMS | CMM | Wireshark | TranslatorX | ThousandEyes | MATS | VMware ESXi | Cisco CIMC | Crestron Toolbox | RTMT | NetScout Certifications: Cisco CCNA (Routing & Switching) ITIL® Foundation Cisco Black Belt ThousandEyes - Stage 1 Crestron Toolbox™ & Appspace (Crestron Technical Institute) I'm passionate about building infrastructure that people can rely on because when communication systems work flawlessly, businesses run better. Outside my core work, I enjoy rap and music creation as a creative pursuit that helps me stay expressive and inspired. 📩 Open to new opportunities in Collaboration Engineering, UC Infrastructure, and AV/VC Operations.
