About me

Intro

Hi there! I'm Hatem, a dedicated software engineer with a deep passion for backend systems and infrastructure. While my journey began in full-stack web development, I've increasingly gravitated toward systems-level work, where performance, scalability, and reliability take center stage. My primary expertise today lies in building sophisticated backend services, and Go (Golang) is my language of choice. I use Go to craft high-performance APIs, elegant CLIs, and resilient distributed systems. My background also includes a strong foundation in the JavaScript/TypeScript ecosystem—especially with tools like Node.js, Express and even React, and Vue—but my focus has shifted toward backend-heavy, systems-oriented engineering. I'm equally passionate about Linux environments and DevOps practices. I enjoy building efficient CI/CD pipelines, working with containers, and optimizing system performance. For me, development isn't just about code—it's about creating reliable, automated, and maintainable systems that scale. Outside of tech, I'm an avid audio and visual arts hobbyist. Creativity fuels my approach to engineering, helping me see problems from fresh perspectives and devise innovative solutions. Let's connect! Whether it's to talk backend architecture, Go systems, or creative coding, I'm always open to meaningful collaboration and conversations that spark growth and innovation.
