About MapYourTech
The story of how personal field notes became a trusted platform for optical networking engineers across 193 countries — connecting real-world experience with practical knowledge.
The Story That Started Everything
From personal field notes to a global engineering resource — here is how MapYourTech came to be.
It began with a real gap. Sanjay Yadav, working as an Optical Networking Engineer, could not find practical resources that connected textbook theory to real-world deployment. So he began taking notes — personal insights from live projects, troubleshooting scenarios from the field, and automation scripts that actually worked.
The Turning Point
When colleagues started requesting copies of those notes, Sanjay recognized something important: engineers do not need more theory. They need practical wisdom from someone who has designed, deployed, and troubleshot real networks.
What started as a personal blog on March 29, 2011 grew into the resource Sanjay had always wished existed — a place where concepts meet implementation, where theory translates to practice, and where engineers help other engineers grow.
What Sets Us Apart
MapYourTech does not just explain concepts. It shows you how to implement them, how to approach troubleshooting, and how to automate them at scale — all grounded in real engineering experience.
Our Philosophy
"Share, Explore, and Inspire with the Tech Inside You."
- Field-tested content drawn from live network deployments across Telco, Cloud, and Submarine environments
- Vendor-neutral analysis focused on standards, engineering principles, and real trade-offs
- Automation-first approach — Python, NETCONF, YANG, and tools that scale to real networks
- Structured learning paths from foundational concepts to advanced architecture and design
- Continuously updated content reflecting current standards, technologies, and industry trends
Meet the Engineer Behind MapYourTech
Nearly two decades of hands-on experience across optical networking, cloud infrastructure, and network automation.
Sanjay Yadav
Optical Networking Engineer & Architect | Founder, MapYourTech | Author
Sanjay has spent nearly two decades at the intersection of optical networking, cloud infrastructure, and automation engineering. From submarine cable trials across the Pacific and Atlantic to building AWS's global optical data center interconnect network, his experience spans some of the most complex and high-stakes network environments in the world.
He has worked with global organizations including AWS, Cisco, Ciena, Ribbon Communications, Alcatel-Lucent, Huawei, and ECI Telecom — solving the kinds of engineering problems that most professionals encounter only in theory. That experience is what drives every course, article, and tool on MapYourTech.
Sanjay is also the author of three published references — Optical Network Communications: An Engineer's Perspective, Automation for Network Engineers Using Python and Jinja2, and Practical Guide for Cracking Optical Interviews — each written to bridge the gap between theoretical understanding and practical deployment. He studied engineering at Dr. A.P.J. Abdul Kalam Technical University.
