What I'm looking for

I’m looking for a mobile-first team where I can build Flutter/Kotlin applications and also deliver AI voice/POS full-stack features, owning multi-tenant backend development with Clean Architecture and modern web UI practices.

Mobil geliştirme ve full-stack mühendislik alanlarında 3 yıllık deneyime sahip bir Bilgisayar Mühendisiyim. Flutter, Kotlin, Node.js ve Vue 3’te yetkinim; Mobil Clean Architecture ve BLoC/Cubit state yönetimiyle sağlam, sürdürülebilir ürünler geliştirmeyi önemsiyorum.

OpenAI API tool-calling ve Twilio WebSockets kullanarak gerçek zamanlı yapay zeka ses modülleri tasarlayıp geliştirdim. Strapi ve PostgreSQL ile multi-tenant SaaS backend sistemleri kuruyor, Vue 3 POS dashboard’larında DDD prensipleriyle iş kurallarını katmanlardan ayırarak kullanıcı odaklı arayüzler üretiyorum.
