A comprehensive learning, project, and portfolio repository documenting my journey into Embedded Linux, from fundamentals to production-ready systems.
- Build a strong, practical understanding of Embedded Linux architecture
- Document learnings in a clear, reusable, engineering-focused manner
- Design and implement real-world embedded Linux projects
- Create a public technical portfolio that demonstrates production-level competence
- Linux internals and system architecture
- Embedded Linux boot process (ROM → Bootloader → Kernel → RootFS)
- Cross-compilation and toolchains
- Buildroot and Yocto Project
- Custom Linux distributions
- Bootloaders (U-Boot)
- Device Tree and hardware bring-up
- Linux device driver development
- Networking (Ethernet, Wi-Fi, PPP, Cellular)
- Security (Secure Boot, filesystem encryption, OTA updates)
- Performance optimization and debugging
- Real-world Embedded Linux projects

This repository follows a learn-by-building approach:
- Every concept is backed by hands-on implementation
- Trade-offs are documented, not hidden
- Emphasis is placed on production thinking (reliability, security, maintainability)
- Embedded Linux learners looking for real-world examples
- Engineers transitioning from bare-metal or RTOS to Embedded Linux
- Recruiters and hiring managers evaluating Embedded Linux capability
- Anyone interested in how Linux runs on real hardware
I am an Embedded Systems & IoT Engineer with experience designing and deploying connected hardware and firmware solutions.
This repository reflects my focus on robust system design, performance optimization, and real-world embedded deployments.
