Emrah G.

I build AI-native SaaS web and mobile applications, specializing in ETL pipelines, data extraction, web scraping solutions, automation systems, and REST APIs using React, React Native, Next.js, Python, Node.js, TypeScript, Tailwind CSS, Supabase, Claude API, OpenAI API. Clean code, production-ready project structures, mobile-first, full responsive interfaces, deployed to the cloud(Vercel, Netlify, DigitalOcean, AWS, etc.)

I specialize in building ad scaling high-performance web and mobile applications, with deep expertise in e-commerce platforms, AI-powered tools, and intelligent chatbots. From concept to production, I design and develop scalable solutions that integrate AI to enhance performance and deliver seamless user experiences. With strong full-stack expertise, I can rapidly transform your idea into reliable, production-ready products and tackle complex technical challenges with confidence.

I also design and build scalable data systems that extract, process, and deliver clean, reliable data - even from complex, protected, and unstructured sources. From high-volume scraping pipelines to fully automated workflows, I create production ready solutions that run continuously, handle scale, and integrate directly into your business systems.

I use Claude Code as my primary development workflow - it allows me to deliver production-quality applications 2-3x faster than traditional development without sacrificing code quality.
