You mentioned that the schedule is tight. This makes me the best candidate for the job as i can deliver just in time for your deadline.
I have a lot of experience working with ELF files as i have made compilers, code generators and operating systems in my past work, all of which require working with ELF executables.
I have multiple years of experience working with x86 assembly, RISC-V assembly and ARM assembly.
I am also an expert C, C++ and Rust programmer.
