2. Yocto Recipe Writing and Optimization:
   • Proficient in creating and managing custom recipes for specific software, optimizing each package to meet limited resource constraints and address memory and performance requirements of embedded hardware.
   • Experience in implementing and updating recipes for specific package versions, ensuring dependency consistency and cache management to improve build times.
3. Hardware and Driver Integration:
   • Deep understanding of hardware module and driver integration within embedded systems, with experience porting and configuring drivers for ARM, x86, and other custom architectures.
   • Expertise in optimizing kernel, modules, and system tools to increase compatibility with specific hardware and reduce the distribution’s footprint.
4. Advanced Debugging and Troubleshooting:
   • Advanced debugging skills using tools like gdb, strace, perf, and detailed build log analysis to address runtime issues, package incompatibilities, or hardware malfunctions.
   • Proficient in embedded platform debugging and in using profiling tools to ensure system stability and reliability.
5. Automation and CI/CD with Yocto:
   • Experienced in integrating CI/CD pipelines for automated Yocto builds, using tools like Jenkins, GitLab CI, and Docker to ensure build consistency and quality. This includes configuring automated jobs that monitor and resolve build errors, ensuring continuous deployment of updates and rapid test cycles.
6. Security Management and Compliance:
   • Strong focus on security within embedded distributions, implementing best practices for image security, such as kernel hardening, configuring security measures in system packages, and frequent updates.
   • In-depth knowledge of compliance with standards such as GPL, LGPL, MIT, and other open-source licenses to ensure distributions meet regulatory requirements.

Achievements and Projects

• Custom Embedded Systems Projects: Developed and deployed custom distributions for specific applications (IoT, automotive, industrial), significantly reducing system startup time and resource usage.
• Build Optimization and Reduction: Implemented solutions that reduced build times by 30-40% through recipe optimization and effective cache management, accelerating development and testing processes.
• System Security and Robustness: Improved system security in various projects by hardening the kernel and implementing sandboxing techniques for critical applications, ensuring integrity and stability in critical operational environments.
