Efe Bayol

I’ve been developing software since 2015, starting as a self-taught developer and steadily expanding across front-end, back-end, mobile, desktop, and IoT. I’ve helped drive the full lifecycle of hundreds of startup projects—from initial planning through final deployment—while also delivering bespoke software for corporate clients.

Most recently, I led end-to-end development as a Technical Lead for a Market Intelligence and Marketing SaaS platform for game developers and publishers. I designed robust infrastructure to process billions of rows of data, turning them into optimized summary tables and intuitive analytical dashboards, using ClickHouse (OLAP) for high-performance dataset management.

I’m especially proud of how I simplify complex data workflows and add intelligence to products by integrating orchestration with Apache Airflow and DBT, and embedding both local and cloud-based Large Language Models (LLMs) into core systems. I also partner with teams as a Freelance Senior Full-stack Developer and currently mentor startups in the ITU Çekirdek Incubation Center—supporting founders with scalable architecture and product development decisions.
