About Me
Hello There!
My name is Lefteris Pachis, and I hail from Chalkida, Greece. I earned my computer science degree at the University of Crete in Heraklion. Following that, I accumulated two years of experience as a software developer in the e-commerce sector. Subsequently, I dedicated a year and a half as a backend developer within a team that revamped an e-learning web application using a microservices architecture. Currently, I'm an Associate Software Developer at a forex and CFD trading company, having transitioned from my previous role at a company specializing in chatbot development.
In my free time, I immerse myself in my love for travel and photography exploration. Furthermore, I find excitement in engaging with game development and digital art.

Anchor Pair 4
This is the result of my research about Nano-scale wireless communication during my Bachelor Thesis. Its about a new routing protocol for 3D wireless nanonetworks (Anchor Pair 4), based on the simulation results of N3 Addressing and routing in 3D nanonetworks. Evaluation experiments showed that Anchor Pair 4 achieves better performance than N3.
