Efe Deniz A.

I am a Senior Embedded Developer specializing in designing, building, and optimizing reliable firmware and IoT systems for real-world applications. With deep hands-on experience across microcontrollers, wireless communication stacks, and low-level performance tuning, I transform complex hardware–software challenges into robust, production-ready solutions. What I Do Best • Embedded Software Engineering: Expert in C/C++, Rust (optional line), RTOS-based architectures, and bare-metal development with a focus on stability, safety, and efficiency. • IoT System Design: Skilled in ESP32/ESP32-S3, STM32, and Nordic SoCs; building secure, scalable systems that connect reliably over GSM/LTE, Wi-Fi, BLE, and MQTT/HTTP protocols. • Hardware–Software Integration: Proven experience integrating sensors, custom PCBs, and edge algorithms with firmware pipelines to achieve real-time performance. • Connectivity & Data Systems: Strong background in building OTA update flows, device provisioning, power management, and telemetry pipelines for large-scale device fleets. • Problem Solving & Optimization: Passionate about debugging, memory optimization, low-power strategies, and designing architectures that stand the test of time in the field. • Full Product Lifecycle Ownership: From concept → firmware architecture → hardware bring-up → testing → deployment → long-term maintenance.
