Electrical Engineer

United States - Last active: 2 months ago - Tests: 7

Hi! I'm an dually degreed electrical engineer but also have very substantial software engineering experience. I'll start with the latter since it is probably more conducive to online work. I am highly proficient in C++, C and Python; as for coding categories, I'm proficient with TCP/UDP/IP, serial (asynchronous and synchronous), USB, bit-bang methods, direct memory access, board bring-up and cross-compilation / non-x86 platforms (specifically ARM and PIC). Further, I'm a Linux enthusiast and have 12+ years using Linux in desktop, server and embedded applications. I have in depth knowledge of U-Boot, RedBoot, Grub, Lilo, Bash, the Linux Kernel, Wireshark, tcpdump, netcat and all the other standard open-source Linux utilities. I'm comfortable with Ubunutu/Debian, RHEL and its associated clones, Slackware and custom Linux builds (creating custom Linux builds is also a skill). As far as electrical and computer engineering, I have a strong background in COTS integration, antennas, satellite design, autonomous sensor design and integration, board schematic and layout, parts selection, satellite communications, VSATs, and various other EE/CPE concepts.
