About Me

I am a 22-year-old Computer Engineering graduate candidate at Alanya Alaaddin Keykubat University (ALKÜ), currently in the graduation phase. As a multidisciplinary systems engineer, my core focus lies in architecting scalable, resilient backend services and bridging hardware with cloud intelligence through distributed telemetry pipelines. My primary software ecosystem is driven by Node.js, Express.js, and C# (.NET), backed by robust relational database design across PostgreSQL, MariaDB, and MySQL. Beyond application layers, I have practical experience deploying production environments on Linux (Ubuntu) VPS setups using PM2 and Caddy (SSL/TLS), alongside modeling enterprise process workflows on Bimser Synergy. My capabilities extend deeply into embedded IoT systems—having architected low-power mesh networks with ESP32 and LoRa (SX1278), as well as evolving the autonomous B&R Breeze platform from an ESP32-S3 and React Native micro-rental prototype into an enterprise facility automation ecosystem. Driven by technical leadership honed as a competitive TEKNOFEST Team Captain and Founding President of the ALKÜ Water Sports and Diving Club, I am eager to bring this end-to-end engineering portfolio into an impactful engineering role.
