Worked on the flipperdevices/u-boot repository, focusing on targeted codebase cleanup within the RISCV architecture. Removed the unused DRAM_BASE macro from arch/riscv/encoding.h, eliminating dead code to improve maintainability and readability without introducing functional changes. This disciplined refactoring effort reduced technical debt and future risk in the boot sequence, supporting easier onboarding and safer evolution of the codebase. Demonstrated strong skills in embedded systems and kernel development, applying C programming expertise and a careful approach to macro-level cleanup. Maintained high standards for code hygiene and reviewability, leveraging Git for changelist management and ensuring traceable, low-risk improvements to core infrastructure.
