Istanbul, Türkiye

Since 2018 I have been building web, mobile and enterprise applications end to end, from idea to production, with a focus on workforce planning, B2B SaaS and AI-assisted solutions.

About

I am an Istanbul-based software developer who has been working on software development, digital product design and technology ventures since 2018. I have experience with web, mobile and enterprise applications, especially systems built on PHP/Laravel, JavaScript/React, React Native and MySQL.

I approach technical development together with product management and business needs. My work centers on workforce and shift planning, B2B SaaS, enterprise system integrations, operational efficiency, cloud infrastructure and AI applications.

By combining my bachelor’s degree in International Relations with my software experience, I look at business processes, organizational needs and the operational impact of technology products together.
