About

I'm a full-stack developer from Türkiye, specializing in the JavaScript and TypeScript ecosystem — from Node.js back-end services to modern interfaces built with Svelte and Vue.js.

I care about contributing to the open-source community. My npm packages — earthquake-turkey, adhan-time-turkiye, easy-mssql and others — provide developer tooling focused on Türkiye. I made 1,354+ contributions on GitHub over the past year.

I also have experience in Discord bot development, desktop applications with Electron, and data processing. I'm currently contributing to Aris888, a metaverse technology company based in Türkiye.
