Hi, I'm Gultekin Kaya! 👋

Fullstack Developer building AI-powered tools & services

I build production web applications that integrate AI — not experiments, but real tools that solve real problems. From nutrition tracking with Claude API to CLI automation, I bring 10+ years of web development expertise to make AI actually work in products.

My foundation in React, Next.js, and Node.js is what makes the AI parts production-ready. I focus on practical AI — tools that save time, automate workflows, and surface insights.

What I Build

🌐

AI-Integrated Web Applications

Full-stack web apps with embedded AI features — chat interfaces, content generation, intelligent search, and data analysis. Built on Next.js + PostgreSQL with streaming AI responses.

🤖

Custom AI Agents & Workflows

Task automation using the Claude API. Agents that handle multi-step processes — data processing, report generation, monitoring, and notifications.

How I Work with AI

I integrate AI where it creates real value — not for the sake of having AI. Every AI feature I build has proper error handling, cost controls, and a clear purpose.

I believe in human-in-the-loop systems where AI accelerates the work but humans stay in control. Production-ready means fallbacks, privacy-awareness, and predictable costs — not just a working demo.
