Managerial contribution: • Recruited, mentored, and retained a skilled dev team for firewall feature development, including AppFlow, GeoIP/Botnet, Dynamic External Objects, Decryption Policies, and networking features. • Hands-on manager responsible of design, development, guidelines, and change requests. • Managed and motivated a dispersed team, fostering collaboration. • Collaborated with NSM team to enhance firewall traffic visualization and alerts. • Led Gen6 SonicOS Hotfix release required for NSM2.3.5 as release manager, collaborating with stakeholders, PM, Program Manager, Dev, QA, and System/Perf Testing.Technical Contributions: • Designed and implemented encryption of IPFIX traffic sent to external collectors such as Analyzer, and NSM 2.3.5. This allowed secure transmission without relying on site-to-site VPN tunnels, improving reliability. • Developed and maintained the functionality to send firewall event logs as IPFIX data to NSM 2.3.5, ensuring efficient and secure communication of critical information. • Designed and implemented firewall health data reporting to NSM, collaborating with stakeholders to gather requirements and define the data format. • Designed and mentored the feature development of storing Geo-IP DB to an external disk. This feature enables closed network setups, which cannot download the Geo-IP DB, to restore the DB from the external disk, ensuring continuous security. • Provided technical guidance and oversaw the development of features requiring data storage to external disks, such as AppFlow reporting and Geo-IP DB data storage.

Managerial contribution: • Played a pivotal role in establishing and nurturing the SonicOS development organization in Bangalore, working closely with the VP/GM of Sonicwall India. Helped in recruitment, refining the recruitment process, onboarding new members, and successfully built a team of 15+ engineers for the bigger organization.• Established an optimal dev environment for the team by collaborating with SonicCore/SDK and IT teams. This initiative facilitated faster onboarding of new engineers with minimal effort, streamlining the overall development process. • Led a team of 6 engineers to successfully deliver on the Gen7 API dev project. Conducted daily scrum meetings, overseeing the progress of engineers and working with the API team to gather requirements. Proactively addressed project challenges by leveraging my expertise as a Firewall Subject Matter Expert, assisting in requirements understanding and translating them into actionable tasks for the engineers and API team. Timely project completion and garnered the trust of the Head of Engineering in the capabilities of the newly-formed SonicOS dev team. • SME for the Next-Gen Policy Engine/Unified Policy Engine, providing valuable insights and support to the SonicOS BLR QA team, and SonicOS PM team.Technical contribution: • Designed and implemented Decryption Policies for Sonicwall's latest Firewalls, which operate on the Unified Policy Engine (UPE). This powerful feature grants user precise control over traffic subjected to Decryption/DPI-SSL. • Ensured optimal functionality and behavior of the Geo-IP/Botnet modules within the UPE framework, contributing to a robust and effective firewall system. • Designed and executed the translation of the FW preference file from Classic mode to UPE mode and vice versa. This seamless transition capability empowers users to switch firewall modes without the need for external tools to migrate preferences.

• Designed and implemented the IPFIX with extensions version 2 format to enhance the reporting capabilities of FW traffic to external data visualizers, such as Sonicwall Analytics. This resulted in richer reports and improved efficiency in presenting data. • Collaborated extensively with the GMS team and Analyzer team to facilitate the transition of the analyzer product to the cloud. This involved debugging on firewalls, network infrastructure, and interpreting/implementing data within the analyzer. • Containerized the Sonicwall internal collector as a separate Docker container running on Linux firewalls. This feature enables the storage of a larger set of Firewall Flow data that persists across reboots. • Designed and developed infrastructure to support the development of Dynamic External Objects and Dynamic Botnets. This functionality allows users to specify external locations to configure the firewall, eliminating the need for manual configuration changes. • Mentored engineers in the team on the development of new features, including Custom Botnet, Custom Geo-IP, and Advanced Flow Server.

Santa Clara

• Developed infrastructure for cloud groups, enabling users to instantiate predefined groups with a single click, eliminating the need for manual configuration. Extended the implementation to support countries and applications. • Maintained and enhanced the Geo-IP and Botnet modules within the Security Services suite of Sonicwall Firewalls. • Maintained and enhanced the Appflow module, facilitating data visualization of traffic (connection/threat/URL) through the firewall. • Implemented enhancements and bug fixes for IP Helper, Mac-IP Spoof, packet monitor, Active connections monitor, and FW ping features. • Collaborated with external data collectors, such as Plixer Scrutinizer, to support Sonicwall's data reporting format, IPFIX with extensions. • Delivered timely customer hotfixes. • Promoted from Staff to Senior position.

• Designed and developed a Perl/C++ based tool to extract hardware module port list information from huge number of verilog files using Verilog PLIs.• Designed, developed and reorganised APIs for accessing transceiver analog parameters across multiple families and also making them data driven.• Develop and maintain speed grade legality checks for High speed serial interface ( HSSI ) transceivers.• Coordinate transceiver speed grade information across multiple departments enabling remarkable turnaround time for time critical customer requests.• Develop, maintain and test the transceiver and pin reporting functionality for the HSSI transceivers.• Static Analysis tool - Coverity Prevent warnings were handled for the entire department.

Huntsville, Alabama, United States

• Collaborated with developers on feature requirements, designed CLI commands, and represented the switch module team in the CLI committee to ensure new commands met requirements and standards.• Automated CLI database verification that ensured clean daily builds and trained an offshore team to maintain the process.• Designed and implemented the CLI, SNMP, and database interface to support the Node Information Advertisement feature.• Implemented port mirroring features across Gigabit-Ethernet ports on Broadcom (BCM) based switches, facilitating efficient data flow debugging. Validated register values and monitored mirrored traffic with Wireshark to prevent flooding issues.• Developed the Manual Switch Alarm (SNMP) to distinguish between automatic card switching and user-initiated actions, enhancing system monitoring capabilities.

Worked for the Clemson Distance Education team. • Web Development and maintenance for the upstate Youthbuild website. • Assisted faculty in creating Podcasts for teaching. • Evaluation of transcription softwares.
