About

I'm a Senior Full Stack Web Developer with 15+ years of web development experience across healthcare technology, IoT, telecom, SaaS and e-commerce. On the frontend I work with TypeScript, JavaScript, Angular, Vue.js, HTML5 and CSS3/SCSS; on the backend with C#, ASP.NET MVC, REST APIs and SQL Server. I care about clean code, maintainable architecture and long-lived production codebases, and I ship through GitHub Actions CI/CD in Agile/Kanban teams. I've put applied AI into production — Gemini Vision, LLM workflows, DeepL — and I use Claude Code, MCP, AI agents and GitHub Copilot every day for coding, refactoring, testing and technical analysis. I'm currently studying Management Information Systems at İstanbul University. Outside of work I'm the father of three daughters; the patience I practise at home shows up in my code.
