const myJourney = {
origin: I started my career as a Civil Engineer, earning both my Bachelor's and Master's degrees from Middle East Technical University in Ankara, Turkey.
pivot: My research in autonomous robotics and soil-tool interaction sparked my passion for software. I found myself writing more MATLAB scripts than structural calculations.
evolution: That curiosity led me down the rabbit hole of web development. What started as building simple websites evolved into architecting large-scale SaaS applications.
present: Today, I'm a Principal Engineer at Babbel Labs in Berlin — the AI-first company under Babbel Group building cutting-edge language learning apps. I'm deeply invested in AI transformation and how it's reshaping how we build software.
venture: On the side, I founded Aida Yazılım, an AI studio that takes companies from strategy to shipped product — from PorlandAI, a RAG assistant for 1000+ employees, to HitTheRoad, an AI road-trip planner now live on the App Store.
passion: I believe in knowledge sharing. Every week, I conduct sessions with my team on AI tools and best practices. Teaching is learning twice.
