****************@*****.***
With 9+ years of experience in Python API/UI Automation Engineering and Web Application Development, I have specialized in automating Access Points, SmartZone controllers, and Layer 2/Layer 3 ICX switches for over 5 years. My work focuses on enhancing network reliability and performance, configuring and managing WiFi access points using enterprise tools, and ensuring secure and efficient wireless network operations.
I have extensive experience in creating, maintaining, and executing detailed test cases for functional, performance, security, and compatibility testing of WiFi access points, alongside testing their interoperability with a wide range of devices and network configurations. My proficiency extends to IEEE 802.11 standards (a/b/g/n/ac/ax), TCP/IP, DHCP, DNS, ICX Layer 2/Layer 3 Switching, WiFi security protocols like WPA2(AES), WPA3(SAE), and routing protocols such as RIP, OSPF, EIGRP, IS-IS, and BGP.
In addition to strong problem-solving skills for diagnosing WiFi issues, I bring expertise in firmware management, cloud platforms like GCE, Azure, and AWS, and automation frameworks such as Robot Framework and Pytest with Python. My background includes working with virtualization platforms (VMware ESXi, Microsoft Hyper-V, KVM) and leveraging CI/CD pipelines for automated testing.
I also have 4 years of experience in Python Web Development, with hands-on expertise in Django, Flask, Shell Scripting, REST APIs, and Linux-based environments (RHEL, Ubuntu). My contributions span end-to-end build, deploy, and test flows, object-oriented programming, and the Agile software development life cycle. I am adept at collaborating with cross-functional teams and documenting development activities at the method and API levels.

Description:
Smart Zone is wireless Controllers which manages Ruckus Access points. Smart zone network controllers simplify network setup and management, enhance security, minimize troubleshooting and ease upgrades for networks built on Ruckus access points and switches
Roles & Responsibilities:
Developed and executed automated test scripts for WiFi testing using tools like Python, Robot Framework, improving test efficiency and consistency.
Automation of SZ/vSZ Controller Features.
Configured and tested WiFi networks, including access points (APs), wireless controllers, and client devices, ensuring optimal performance and coverage in various environments.
Configured and deployed virtualized WiFi environments using platforms such as VMware, Hyper-V, or KVM, enabling scalable and flexible testing of WiFi networks in a controlled setting.
Conducted extensive scalability testing to evaluate the performance and behavior of WiFi networks under increased loads, including a high number of concurrent users, access points (APs), and traffic flows.
Monitored key performance metrics, such as throughput, latency, and packet loss, during scaling tests, using tools like Wireshark, Grafana, or custom dashboards, and analyzed results to identify performance degradation or bottlenecks.
Configured and managed ICX Layer 2 and Layer 3 switches, including VLANs, trunking, port security, spanning tree protocol (STP), and routing protocols, to ensure optimal network performance and security.
Implemented and managed Virtual LANs (VLANs) on ICX switches to segment network traffic, improve security, and optimize network resource utilization across different departments or services.
Configured and optimized routing protocols such as OSPF, BGP, EIGRP, and static routing on Layer 3 ICX switches, ensuring efficient and reliable inter-network communication.
Implemented security measures such as Access Control Lists (ACLs), port security, DHCP snooping, and IP source guard on ICX switches to prevent unauthorized access and protect against network attacks.
Configured Quality of Service (QoS) policies on ICX switches to prioritize critical network traffic, ensuring optimal performance for voice, video, and other high-priority services.
Performed firmware upgrades and software updates on ICX switches to ensure devices are running the latest, most secure, and stable versions of the operating system.
Conducted throughput, latency, and range tests to evaluate WiFi network performance under various conditions, including different AP placements, channel configurations, and load scenarios.
Tested WiFi security features such as WPA3, WPA2, 802.1X authentication, and guest network isolation, identifying vulnerabilities and ensuring compliance with security standards.
Used tools like Wireshark, and AirMagnet to perform spectrum analysis, identify sources of interference, and validate RF signal strength, coverage, and channel utilization.
