Hi, I'm Serhat Sönmez
Hi, I'm Serhat. I'm a senior software developer with 8+ years of
experience.
I love solving complex problems, learning new technologies and creating new things. I'm
also obsessed with clean code and development architectures.
I began my career by working as a freelance developer. After few years as a software developer, I started training on C#, .NET Core, Python and giving guidance to enterprises.
I've also worked as a security researcher for a couple of years. I continue to improve in the field of security, especially on secure code development and web vulnerabilities.
Currently, I'm co-founder and software team lead on Arenpi, also developing new cybersecurity projects with Seccops Company.
