Early Life and Academic Foundation
Arun’s journey into the world of networking began in earnest after completing his engineering degree, during which he simultaneously worked as a network administrator at a training institute. His passion for networking was evident early on as he pursued industry-standard certifications like MCP,CCNA, CCNP, and CCSP, laying a strong theoretical and practical foundation. These formative experiences shaped his technical rigor and pedagogical instincts, evident in his later role as a top-rated trainer.
Professional Journey
Initial Forays and Rapid Ascension
Arun began his professional career at IndiaOptions.com, where he served as a network administrator and educator. This hands-on experience with Cisco lab equipment and student mentoring cemented his foundation.
He then moved to HCL Technologies, where he led IPSec testing on a range of high-end Cisco routers. Recognized for optimizing test runtimes and introducing complex features like SSLVPN into QA cycles, Arun quickly rose through the ranks, eventually serving as the technical point of contact for both hardware and software IPSec testing.
Expanding Impact Across Industry Giants
At IBM India, Arun led knowledge transfer and training efforts for Nortel VPN Gateway systems. His leadership helped establish a new SQA team and accelerated the onboarding process for new engineers.
His tenure at Stoke Networks (later acquired by Mitel) was marked by innovation, especially in IPSec interoperability and redundancy testing. Notably, he executed soak tests validating router resilience and represented QA at international customer demos.
At Ericsson India, Arun served as a Lead Engineer for platforms supporting LTE mobile networks. His automation breakthrough using robotic arms for router testing (R-Arms) was so influential that it was presented at the Automation Summit in Stockholm.
Leadership at Nokia
Currently at Nokia of America Corporation, Arun leads the platform qualification and performance tuning of VSR and Container based routers, ensuring they meet the demands of modern data centers. His automation of in-house traffic generators reducing dependency on costly third-party tools—has yielded substantial savings.
He also improved Express testing systems used by developers, slashing test cycle time by 22 minutes—a huge boost in a large-scale development environment. His role continues to bridge the gap between customer deployment needs and platform engineering.
Leadership and Innovation
Arun exemplifies a leadership style rooted in technical mentorship, process innovation, and cross-functional collaboration. Whether pioneering new test automation methods, orchestrating knowledge transfers across continents, or leading platform qualifications, he brings a unique blend of foresight and hands-on execution. His work not only optimizes internal systems but also directly contributes to product reliability, customer satisfaction, and cost efficiency.
