OLCAY ERTAŞMIŞ
Computer Engineer crafting high-performance systems, clean game architectures, and scalable live mobile games.
I approach game development not just as assembling assets, but as constructing robust, maintainable, and high-throughput software systems. With a strong Computer Engineering foundation, my focus lies in decoupling game logic, optimizing memory allocation, and designing extensible live-game architectures.
Whether independently orchestrating full-cycle mobile releases with IAP/Ad SDKs, writing custom level editors for production teams, or managing complex live-ops A/B test pipelines via Nakama and Remote Config, my priority is code predictability and top-tier player experience.
Core Architectural Competencies
Architectural Patterns
Writing decoupled, testable, and maintainable systems using industry-grade patterns.
Live-Ops & Backend
Full client-side integration of server-driven systems, analytics, and telemetry.
