Seeking the opportunity to work as an Infrastructure/DevOps Engineer and be able to give back to the community whenever possible. I've been working on and around the Joyent Triton Private and Public Cloud Platform. The discovery of Joyent was a bolt of lightning to why I needed to be a Linux, and Unix Engineer. I keep myself up to date on technology by using some of the following resources. Joyent is the company that brought the world Node.JS, and was recently acquired by Samsung for its excellent container native platforms.

The following resources have equipped me with the ability to build and utilise clouds. Whether they be public or private, running on UNIX or Linux.

https://www.joyent.com/blog (Joyent’s Technical Blog)

https://queue.acm.org/ (The Association of Computing Machinery)

http://dtrace.org/blogs/ (Blogs about Infrastructure and Systems from the Top Engineers in the Industry)

https://cr.joyent.us (Code Review for Joyent)

After a decade of operating systems at different scales I have the ability to now spot the pros and cons about systems, and their toll on operations. For private cloud implementations this includes the commodity hardware required for compute, networking, and storage.

I'm fluid in the 12 factor application (https://12factor.net/), and the patterns and anti-patterns around them. Given my experience I am now a huge supporter of what is known as the Autopilot Pattern. The autopilot pattern automates in code the repetitive and boring operational tasks of an application, including startup, shutdown, scaling, and recovery from anticipated failure conditions for reliability, ease of use, and improved productivity. (http://autopilotpattern.io/)

I have become an independent thinker who judges and critiques technology on its robustness, performance and technical merit.

Technical Abilities worth mentioning:

Ability to utilise Any Public Cloud's (AWS, Azure, Joyent, Digital Ocean, etc) APIs and Services to construct a Safe, *Enterprise-Grade*, Developer Friendly, infrastructure that is embodied around the established values of the team I am a part of.

Ability to Architect, Debug, Operate Linux Container Orchestration Platforms such as Mesosphere and Kubernetes.

Ability to think about the TCO (Total Cost of Ownership) of each component that creates a finely tuned infrastructure.

Ability to provide end to end security throughout the infrastructure. This has become know as providing “Continuous Security”.

Ability to build decoupled infrastructure in the enterprise with minimal to no downtown.

Ability to write programs to solve a variety of issues in NodeJS.

Ability to debug problematic applications in the enterprise to solve issues.

Ability to construct Private Cloud infrastructure that are as easy to use as Public Cloud.

Ability to venture into areas where I have limited knowledge, and smile.

Feel very comfortable in Modern Operating Systems such as SmartOS, Linux, Windows Server, FreeBSD and ESXi.

Configuration Management: Using the Infrastructure as Code Methodology, Powershell, Jenkins, Ansible / Terraform / Packer / NodeJS / Git etc.

Networking: VRF, VLAN, VXLan, LACP, Reverse Proxying, SSL, Load Balancing, CARP, DNS... etc.

Languages: Javascript (Node), Powershell, Some GO, Bash, Batch

Storage: ZFS, Object Storage, Traditional Proprietary SAN / NAS solutions. VNX, Compellent, Tintri, EqualLogic etc.

Demo Code Challenge Application:

Restful Fibonacci Array Service in NodeJS: https://github.com/smithx10/rest-fibo

Examples of ability to Debug and inspire change in Open Source Projects:

Finding a bottle neck in SmartOS’s imgadm application and fully demonstrate where we are bottle necked with DTrace and Flame Graphs: https://github.com/joyent/smartos-live/issues/718

Pull Request on the open source project Ansible: https://github.com/ansible/ansible/pull/35919

Examples of Self-Motivation and ability to learn:

While working for certain enterprises I have discovered that getting a proper lab, or testing environment for infrastructure engineers was usually somewhat challenging do to politics. Because of this I built my own lab that runs Joyent’s Triton, and Manta. This allows for me to test and develop quickly. I have been able to deploy Mesosphere, Kubernetes, and many other mega orchestrators in order to find the Pros and Cons of each and test complex ideas without hesitation.

My lab stack (https://twitter.com/bruce_smith_it/status/931555424322686976 ):

Routing (Gateway to Internet): Ubiquity EdgeRouter Pro

Firewall (Internal): NPF on NetBSD

Switch Fabric: Quanta lb6m-10GB and Quanta lb4m-1GB,

Compute: Skull canyon with 10GB (HeadNode), 3 Quanta S210-X22RQ 2x E5-2670 (Compute Nodes)

OS: SmartOS

Storage: 40TB usable, Manta, ZFS
