About Me.
A glimpse into who I am and what drives me.
I'm Yasin, also known as Yashinu — a 22-year-old developer from Turkey with a fervent drive for self-improvement. I specialize in backend architecture, building scalable SaaS applications and AI-integrated tools with TypeScript, NestJS, and cloud technologies.
Currently working as a Full-Stack Developer at sixtynine.digital while pursuing degrees in English Translation & Interpreting at Cag University and Computer Programming at Anadolu University. My multilingual background (Turkish, English, Japanese) gives me a unique perspective in global software development.
With 50+ delivered projects ranging from RESTful APIs to community platforms and Discord bots with 337+ GitHub stars, I enjoy turning complex problems into elegant, performant solutions.
