💼
Software Engineer
LC Waikiki · Istanbul
Nov 2021 – Present
Started as a Specialist and promoted to Engineer in April 2025 after taking an active role in critical operational transformations and delivering hardware-level solutions.
  • Digital Transformation: Kiosk solutions and hand-terminal & mobile applications were built to digitize in-store operations.
  • Hardware & Custom SDK: An in-house communication layer for Zebra printers and Bluetooth operations was developed via Method & Event Channels, eliminating all third-party dependencies.
  • Architecture Modernization: UI/UX modernization and Clean Architecture adoption were led across projects; technical decision-making and roadmap planning were owned end-to-end.
  • End-to-End CI/CD: A full CI/CD pipeline was established using Firebase App Distribution and automation tooling, significantly accelerating release cycles.
  • Tech Debt & Refactoring: Architectural improvements were applied to reduce code complexity, optimize memory management, and boost SQLite query performance.
