I work for Intelsat. I have been using Python Since 2011. I previously worked in Integration of Embedded Linux, writing low level firmware for Arm cortex M3 based micro controllers and device interfacing using Python. Right now I am writing Python tools to Analyse system logs.
Also I am a co organizer for Chennaipy. I have been volunteering Chennaipy meetup since 2011.
I never loved programming in college. Python Changed my view of programming. After learning Python I learnt c and worked in Embedded system. Python Changed my career in to right path.

In the age of high-level frameworks and AI-driven development, it's easy to treat the network as a black box. But what really happens when your Python code calls requests.get() or communicates with a microservice? What really happens, when you visit a website? This talk peels back the layers of abstraction, returning to the fundamentals of networking that power our increasingly interconnected world.
We'll embark on a journey from the familiar OSI model (remember "Please Do Not Touch Steve's Pet Alligator"?) to the observable reality of network packets. Using Python and the Scapy library, we will dissect the lifecycle of a simple web request. We'll witness the DNS lookup, the dance of the TCP handshake, the secure establishment of a TLS session, and the flow of HTTP/S data.
Forget abstract diagrams; we'll programmatically construct and inspect packets, comparing what Scapy reveals with what your browser does silently. The goal? To empower Python developers to really look at netw
