About me

Hello! My name is Çağan Efe Çalıdağ, but I prefer to be called Çağan. I am a year old full-stack developer, designer and technology enthusiast. I am currently a Math-Info (Mathematics & Computer Science) undergraduate student at Université Paris-Saclay. (Click here to see my grades, updated automatically through n8n every few days.) I have been "programming" since the age of 10, but I started taking it more seriously when I was 12 and I have been learning and developing my skills ever since. I have experience in various programming languages, frameworks and tools. I am also familiar with some design tools to help me with web development. I am currently working on numerous projects, and I am looking for a potential collaboration or internship opportunities to gain experience and improve my skills. I am a very curious person, and I love learning new things. Being a very hard-working and solution-oriented person, I love taking on challenges and solving problems. My innovative and creative thinking skills help me to come up with unique solutions to problems. Nowadays, I am mostly interested in automation and AI integrated full-stack and mobile app development. I also love data privacy, thus many of my recent projects (as of 2025) prioritize little to no telemetry/data collection, local deployment, self-hostability (if online) and offline use. The project I am focused on as of 2026 is P.O.T.A.T.O , A locally running and vocal AI tool operator with a web GUI and many useful tools. It is also open-source!

I really only learn programming languages, frameworks and other technology related things in order to use them for personal or collaborative projects, rather than use them for my CV. Therefore you won't be seeing any programming language certificates in here for a while. You can however visit the pages I made for my projects where I explained which frameworks, services and languages I used, while also providing some screenshots in case you don't want to sign in to see their content.
