Hi 👋
Furkan Koseoglu

About me

I was born in 1998 in a small village in Van, Turkey. My interest in technology began in high school, where I spent much of my free time exploring Android firmware and modifying phones for fun. I later pursued a degree in Computer Engineering, graduating with a 3.3 GPA (out of 4.0).

During my studies, I completed a remote internship as a Fullstack Engineer with a company based in London, UK — prior to the widespread shift to remote work. Before graduating, I began my professional career as a Frontend Engineer. Over the next two years, I advanced to a Senior Fullstack Engineer role, and eventually became the Co-Founder and CTO of Polymet AI. I am now seeking my next opportunity, excited to bring my experience and passion for technology to a new challenge.

Project Moonshot

Technical Co-Founder

Mar 2021Mar 2022

We have built an app that suggests daily activities and eco-friendly brands to people who are trying to live more sustainably. When people start to switch to a sustainable lifestyle they need to do a lot of research and find out what they will do on their own. We have helped these people to find those things, do it with a community and see the collective impact. Previously we worked on Nemria and Carbofil is the result of this learning process!
