About

From idea to launch,
I build AI-powered products
end to end

I'm a full-stack software engineer at Boğaziçi Institute and co-founder & CTO at CXDEM, building AI-powered products and SaaS platforms for companies.

Three platforms at Boğaziçi Institute, built from scratch and serving 300,000+ users. I also raised boenstitu.com's Lighthouse score from 50 to 90.

A customer chatbot and employee productivity tools on OpenAI and Anthropic.

Products at CXDEM: Antops (Teams, Slack and Jira in one B2B platform), dersnot (AI-powered study platform), PoCify, and WumpUP (90+ bots across 50+ Discord servers).

Infrastructure for dozens of apps on Docker, Traefik and Cloudflare, plus a self-service deploy platform with GitHub Actions and automatic SSL.

As one of only 9 official Kommo partners in Türkiye, I've automated sales pipelines for 5+ companies and cut customer response time by 92%.

    Çoğu kişi Claude Code'u tek bir asistan gibi kullanıyor. Ben farklı bir şey denedim: ona bir CTO gibi davranmayı öğrettim. Artık iş gönderirken sadece ne istediğimi yazıyorum, gerisini sistem hallediyor: - İşi triyaj ediyor (sohbet mi, küçük düzeltme mi, gerçek geliştirme işi mi?) - Disiplinlere bölüyor - Doğru uzmanları paralel çağırıyor (backend + frontend + ui-ux aynı anda) - Bir kalite kapısından geçiriyor (code-reviewer, hassas işlerde security + qa-test) - İşi tamamlıyor ve tutarlı cevap dönüyor. - İçerisinde bulunan token dostu skill ve eklentiler sayesinde yoğun işlemler altında dahi düşük token kullanımıyla tasarruf sağlıyor. Reponun içinde: - 21 uzman agent (backend, frontend, motion, mobile, devops, security, database, payments...) - 55 skill (framework uzmanlığı, premium tasarım, güvenlik, test, performans) - Plugin + ayar şablonu, yeni makineye tek komutla kurulum runbook'u Repo: https://lnkd.in/dYRjQ6RH
