I am a senior full-stack and mobile engineer with 15+ years of experience delivering scalable applications for startups, enterprises, and government projects.

My track record includes: • Leading Overtune’s flagship AI-powered music creation platform, helping secure $2M+ in funding. • Building Türkiye’s largest government iOS app (ÖSYM), serving millions of citizens with zero post-launch issues. • Architecting high-traffic fitness and wellness apps with 60,000+ daily users. • Consulting and mentoring teams across Europe and Türkiye on scalable Flutter development.
