HARIKA VADLA

Having designed, secured, and optimized large-scale enterprise networks in multi-vendor environments
such as PaloAlto, Cisco Firepower, Fortinet, Check Point, Juniper SRX, and Azure/AWS cloud
infrastructures, I am a senior network security engineer with more than 8+ years of experience. Solid
knowledge of advanced routing/switching (OSPF, BGP, EIGRP), SD-WAN (Viptela, VeloCloud), firewall
engineering, Zero Trust security, and Layer 2/3 network design. Competent in end-to-end hybrid
connectivity, AWS VPCs, Azure VNets, ExpressRoute, VPN/Direct Connect, and cloud networking.
Practical experience putting enterprise wireless solutions into practice using Cloudflare Zero Trust,
Zscaler ZIA/ZPA, Cisco ISE, Aruba ClearPass, Cisco WLC, Aruba MC/MM, and Juniper Mist for safe,
identity-driven access. Excellent background in traffic engineering, QoS, micro-segmentation, and load
balancing using F5 BIG-IP LTM/GTM and AVI (Illumio).
Capable of automating setup, monitoring, and change management with Ansible, Python, and REST
APIs. Knowledgeable about creating HLD/LLD papers, carrying out intricate firewall migrations and
upgrades, and accurately identifying the root cause of high-severity issues. Competent in large-scale
network modernization, cross-functional cooperation, and providing scalable, secure, and resilient
infrastructure that satisfies enterprise performance and compliance requirements.
