In my role as a Lead Network Engineer, I embarked on a transformative journey to reshape our company's remote access infrastructure using Netskope ZTNA (Zero Trust Network Access). With an unwavering commitment to innovation and a passion for security, I orchestrated a comprehensive project that not only streamlined remote connectivity but also significantly elevated performance, simplicity, and data protection.

Harnessing the power of Netskope ZTNA, I architected a solution that replaced disparate IPsec and SSL VPN clients with a unified Private Access framework. This strategic shift eliminated the complexities and vulnerabilities inherent in the previous setup, resulting in a remarkably streamlined and secure remote access experience.

Through meticulous planning and collaboration with diverse teams, I intricately designed and implemented the new ZTNA infrastructure. This encompassed designing intelligent policies, refining access controls, and seamlessly integrating remote user internet traffic security. The outcome was two-fold: a substantial reduction in network complexity and a noteworthy boost in performance and security.

The project's impact extended beyond technical upgrades. It reflected my dedication to operational excellence and my commitment to fortifying the organization's security posture. By adopting a Zero Trust approach and empowering remote users with secure, efficient access, I played a pivotal role in elevating both user experience and data protection.

I'm enthusiastic about sharing insights and experiences in the dynamic realm of network engineering and security transformation. Let's connect to exchange thoughts and explore how strategic networking can drive innovation, enhance cybersecurity, and foster a more resilient digital environment.

In my capacity as a Network Engineer, I spearheaded a transformative project that redefined our company's Wide Area Network (WAN) infrastructure using VMware NSX SD-WAN (formerly Velocloud). Guided by an unwavering commitment to innovation and operational excellence, I orchestrated a comprehensive overhaul that not only streamlined our network but also significantly enhanced performance, availability, and cost-effectiveness.

By leveraging the power of VMware NSX SD-WAN, I engineered a solution that seamlessly replaced complex IPsec VPN tunnels and augmented traditional MPLS connections. This strategic shift eliminated the intricacies and limitations of the previous setup, resulting in a remarkably simplified and agile network architecture.

Through meticulous planning and collaboration with cross-functional teams, I meticulously designed and implemented the new SD-WAN infrastructure. This encompassed optimizing traffic routing, creating intelligent policies, and orchestrating failover mechanisms that ensured uninterrupted connectivity even in the face of disruptions.

The outcome was twofold: a substantial reduction in both cost and complexity and a remarkable boost in network performance and availability. This achievement wasn't merely a technological upgrade, but a testament to my dedication to delivering tangible business outcomes. By enabling the organization to harness the full potential of modern networking technology, I played a pivotal role in elevating operational efficiency and positioning the company for future growth.

I'm passionate about sharing insights and experiences in the dynamic field of network engineering and SD-WAN transformation. Let's connect and explore how strategic networking can drive innovation, streamline operations, and shape a more resilient digital landscape.

In my role as a Network Engineer, I undertook a pivotal initiative to bolster our company's cybersecurity posture through the strategic deployment of Palo Alto firewalls. Guided by a commitment to excellence and a relentless pursuit of security best practices, I orchestrated a comprehensive project that aligned seamlessly with the Center for Internet Security (CIS) benchmarks and industry-leading standards.

Drawing upon my extensive expertise in network engineering and a deep understanding of emerging cyber threats, I meticulously designed, implemented, and optimized the Palo Alto firewall infrastructure. Collaborating closely with cross-functional teams, I ensured a seamless integration that not only fortified our digital defenses but also optimized network performance.

Throughout the project lifecycle, I championed a proactive approach to risk mitigation, devising custom policies and rules to cater to our organization's unique requirements. By diligently monitoring and fine-tuning the firewall configurations, I upheld an agile defense mechanism capable of swiftly adapting to evolving threat landscapes.

This endeavor was more than a technical deployment; it was a testament to my unwavering commitment to safeguarding critical assets and fostering a culture of cybersecurity awareness within the organization. By adhering to CIS benchmarks and industry best practices, I contributed to elevating our security posture to new heights, earning the trust of stakeholders and positioning the company at the forefront of digital resilience.

I invite you to explore the possibilities of collaboration and knowledge sharing as we navigate the ever-evolving realm of network security. Let's connect to exchange insights and experiences, working together to ensure a safer digital future.

In my role as a Lead Network Engineer, I undertook a visionary endeavor to establish a state-of-the-art on-premises data center in Kolkata. Guided by a fervent dedication to innovation and operational excellence, I masterminded a comprehensive project that encompassed every facet of data center design, migration, and optimization.

From the ground up, I meticulously crafted a greenfield data center facility that adhered to the highest industry standards.
