Senior Mobile Engineer

Senior mobile engineer with 6+ years shipping 30+ production apps for international clients across the UK, Turkey, and beyond. I started with Android Native (Java/Kotlin) in 2018, added Flutter in 2022, and Python backend + multi-LLM AI orchestration in 2023 — holding all three simultaneously.

I've led engineering teams of 3–6, managed full product lifecycles, and built everything from food ordering apps to an AI-powered SaaS that generates entire Flutter applications from a single natural-language prompt.
