<p dir="auto" style="color: #3a383f; margin: 0 0 1rem;" align="initial">My name is Eslam El Hefny. I'm an MSc researcher at Zewail City of Science and Technology in Egypt, and I work professionally as an Embedded Linux Software Engineer. I'm interested in contributing to the <strong style="font-weight: 600; margin-top: 0;">"Improving the STM32F4 with GPIO, SPI, DMA"</strong> project for GSoC 2026.</p>
<p dir="auto" style="color: #3a383f; margin: 0 0 1rem;" align="initial"><strong style="font-weight: 600; margin-top: 0;">About Me:</strong></p>
<p dir="auto" style="color: #3a383f; margin: 0 0 1rem;" align="initial">I have been working with embedded systems for several years, both professionally and as an instructor.</p>
<p dir="auto" style="color: #3a383f; margin: 0 0 1rem;" align="initial">I've trained over 2,000 students in embedded systems, C programming, and microcontrollers at various institutions.</p>
<p dir="auto" style="color: #3a383f; margin: 0 0 1rem;" align="initial">My hands-on experience includes extensive work with STM32 microcontrollers (stm32 f40 series), where I've developed bare-metal drivers for GPIO, SPI, I2C, UART, and DMA peripherals.</p>
<p dir="auto" style="color: #3a383f; margin: 0 0 1rem;" align="initial">I also run a technical education platform called EmbeddexAI where I create content on embedded systems and RTOS concepts.</p>
<p dir="auto" style="color: #3a383f; margin: 0 0 1rem;" align="initial"><strong style="font-weight: 600; margin-top: 0;">Proof of Work:</strong></p>
