    Peter Green

    Infrastructure Architect/Engineer/System Administrator

    United Kingdom - Last active: 07/04/2014 - Tests: 3

    I have almost a decade of experience working in the industry and gained much experience working with both large corporate clients and small start-up organisations. This exposed me to working with a range of environments; delivering scalable, resilient platforms for high-traffic sites using Amazon Web Services and collaboration platforms hosted on a client’s own infrastructure. Having worked with a wide variety of technologies and clients helps me in analysing a client’s situation and suggesting platforms or solutions to suggest, or being able to work with a pre-existing environment. When I started my career, my focus was traditional system administration; assisting in managing a corporate network, building servers and dealing with support. However, I soon developed a passion for building and maintaining server environments, which lead me to begin learning and adopting processes, tools and work flows to automate build processes and environment management. This includes working closely with software developers to implement workflows that allow for smooth, automated, releases of code and the rapid deployment of development environments. These practices have been codified by the term “DevOps” and it addresses a lot of the problems traditionally associated with software development and deployment.

    Electrical Engineer

    United States - Last active: 3 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.
