Resume of Blain Smith
I am a software engineer always hungry for new challenges and problems to solve, be it tackling online video to disrupt the cable industry, building backend systems for multiplayer AAA games, pushing packets around the internet at Layer 1, or building a motor for my '90 Mustang. I also enjoy the challenge of powerlifting and strongman to push my body to extraordinary limits.
I love working on low level and distributed systems. I can be dangerous with web design and front end work, but my heart is in pushing packets, performance improvements, profiling, and optimizations with compiled languages.

Wolfjaw Studios: Principal Software Engineer, Partner
August 2019 - December 2021
Wolfjaw crafts compelling experiences through our expertise in building game services, player engagement tools, and companion services. Wolfjaw also makes it easy to curate your video content and drive viewership by equipping your team with a custom suite of streaming solutions, applications, and analytics tools. We are hired as consultants by some of the most popular video game and entertainment companies in the world.
- Every Principal Engineer is expected to be a solutions architect on their primary project as an individual contributor, but also serve as a technical lead on a secondary project to guide other engineers. This gives us a way to have more projects than solutions architects and a way to build up our employees to become technical leads themselves. Some of the additional work here includes bootstrapping projects for proper setup, tooling, CI/CD, and security guidelines to empower other developers to dive in and be productive with minimal friction.
- Created a series of internal projects in Go to showcase the different parts an online game needs in the modern age. Some of these educational projects are a matchmaking service, leaderboard services, packet routing service, authentication service, telemetry service, and player inventory service.
- Most client projects I’ve worked on are under strict NDA so they cannot be listed, but what I can mention is that I have touched all aspects of a multiplayer game:
- Server allocation and scaling
- Game client/server integration to external services in C, C++, and C#
- Custom matchmaking services
- Low level TCP/UDP packet routing in Go
- Load testing, benchmarking, and performance tuning Go services
- Sit in on sales calls with our business development team to talk to potential clients to understand their needs from a technical perspective
Kinetic: Senior Software Engineer
December 2017 - August 2019
Kinetic is attempting to change the way people think about safety by equipping factory and warehouse workers with AI-enabled kinematic trackers to analyze and eventually predict work-related injuries.
- Designed and implemented, in Go, the deployment of device management infrastructure with Amazon IoT and our custom Go APIs to sync device state changes, transmit sensor data securely, and issue software patches remotely.
- Worked closely with data scientists to design and implement, in Go and C, their trained models onto devices for inferring kinematic movement. Wrote a custom clone of Tensorflow so it worked on our low power, battery operated, wifi-disabled devices during work hours.
- Redesigned and reimplemented our REST API, in Go, to be more performant, reliable, and resilient. This also included best practices for metrics monitoring with InfluxDB for latencies, response times as well as CPU, memory, and I/O.
- Co-authored our custom Math Engine that performed computations of the aggregated sensor data to be made available to customers through a dashboard. We implemented our custom computations with a DAG to ensure deterministic results based on user input.
- Mentored junior engineers and trained them in Go, AWS, Rust, and C. Also helped them level up their skills in general software engineer best practices like unit testing, integration testing, software design, requirements gathering, RFC writing, etc.
Odd Networks: CTO, Senior Software Engineer
March 2015 - December 2017
Odd Networks was born out of MadGlory to build cross platform video and subscription management platforms for gaming, mobile, and tv connected devices. Our platform supports all major online video providers (OVP), Brightcove, Ooyala, JWPlayer, and Vimeo and our SDKs are used to build apps for Roku, Amazon FireTV, AppleTV/iOS, and AndroidTV/mobile.
- Designed and implemented the primary video content metadata API mimicking a high performance read cache that services devices and sits in front of the OVPs as its upstream sources.
- Designed a plugin interface system for the content API to allow for writing data providers from any upstream source that provide video and playlist data.
- Worked with other app developers to design the app SDK for Roku, Apple, Amazon, and Android apps each in their native languages.
- Built and maintained the first live poker video app for XBox 360 in C#.

Harvard School of Public Health IT Dept: Senior Programmer
August 2005 - October 2012
I spent most of my career as a programmer at Harvard School of Public Health (HSPH) in their IT department with only 1 other programmer. Each graduate school at Harvard has their own IT department with dedicated staff. I was on the IT Web Team in charge of everything web technology related.
During the first homepage redesign, we built a custom CMS to suit the needs of the content publishers in the school and worked closely with the marketing department to accomplish this. I also created the school’s first online course evaluation system that integrated with the registrar’s system. This system not only allowed students to evaluate their courses and professors, but it also allowed those professors to run reports to see aggregated results and read feedback from student comments.
Another large school-wide initiative was the HSPH Forum (https://theforum.sph.harvard.edu) which involved building a live video broadcasting studio and managing those live events through a website we built on WordPress. I became proficient in streaming video over the web during this project since we needed to target as many devices as possible. This initiative generated many viewers because their aim was to be a cornerstone for news and information in the field of public health.
Other smaller tasks I was responsible for was supporting the core departments of the school with any web-related jobs. These jobs put me front and center with tenured professors, high ranking administrators such as Deans and Directors of their departments. Gathering requirements, asking questions, and helping them achieve their project goals was priority #1. I made a good name for myself amongst those people and they grew to trust me which, according to my boss, “was hard to do because of their high expectations and the status they carry within Harvard”.
June 1998 - August 2002
interlinkONE was my first programming job while I was still in high school. I went to a technical high school which offered an IT program and they offered an internship program that I took advantage of.
During my time there I wrote web reporting software in ASP 3.0 that pulled from SQL Server databases for mutual funds clients. Later I spent time working on their product offering for an integration sales and marketing solution for lead generation, lead tracking, order management and fulfillment. I also worked on a custom build GitHub-like software tracking system so we could manage versions and releases of our product and testing with our internal QA team. We called them SMTs (Software Modification Tickets).
I spent a lot of time in school transferring and attending classes trying to complete my B.S. degree in Computer Science. Due to changing degree requirements, time commitments and responsibilities, I decided to focus on my career, and that decision has paid off. Having the opportunity to be employed by companies/institutions who believed in me, my skills, drive and dedication to succeed, I was able to achieve the goals listed above.
