The Reasoning and Decision Making Behind 10-20.io's Cloud Infrastructure 10-20 is a location sharing and encrypted communications platform allowing first responders to use their phone instead of an expensive fake-radios (most "radios" are LTE phones that look like radios), saving them tens of thousands of dollars a year. Here is the infrastructure powering that platform, and the reasoning behind my decisions. entrepreneurshipengineering managementdevopsinfrastructure +9

Joined Accenture as an FTE

Personal

Banana Man Software was something I built, and I'm closing that chapter to join a great team at Accenture Federal Services. With a client contract coming to an end, going W-2 was a tough call, but when the people and the project are right, it's a no-brainer. Bigger team, bigger impact, bigger things to build.

Code and Coffee

Hacktoberfest is for developers to come together in-person and show off and talk about what they've been working on in a show-and-tell manner. If you've gone to Code & Coffee before, this is just Hack n' Tell but now there's merch.

Testimonials

“I had the pleasure of working with Lee for two wonderful years. He's everything you want in a software engineer: intellectually curious, thoughtful, and thorough, yet astute enough to cut through the noise and get things done efficiently for the benefit of his clients. Lee is also personable and genuinely fun to work with. He has an infectious enthusiasm for software development that radiates to everyone around him, and that positive energy helps fuel the team's perseverance when challenges come up.
One final word about Lee is that his approachable personality, combined with his technical expertise, makes him a trusted thought leader. When a team, or even a client, is contemplating next steps and needs someone to talk things through, Lee is who they turn to. He is certainly who I turned to, and he is someone I would recommend without hesitation.”

Supervisory IT Specialist, U.S. Department of State

“Lee is an exceptional engineer and an even better teammate. In our time working together, Lee consistently took the time to mentor newer members - breaking down technical concepts into clear, understandable steps. Even going out of way and providing a structured learning path to junior developers on different programming languages and concepts. He was not only skilled in coding, but was also the go-to person when a teammate needed guidance.
He has great instincts for designing with scalability and reliability in mind. He improves not only the codebase, but the whole team's effectiveness and confidence. I'd work with him again in a heartbeat!”

Software Developer, Deloitte

“I am writing to recommend Lee Brannan. I am glad to provide this on his behalf as his project manager during his time on [ project ]
Lee has served as a Senior Software Developer on our project, where he owns Power Pages work. He consistently sees our user stories through to full completion, not just writing code but making sure it lands correctly in production and is inquisitive so that users have the best experience possible. He's proactive about pulling additional work from the backlog, and he's a reliable partner to our QA testing team, regularly making sure the team as a whole gets our features out the door.
Beyond development work, Lee brings broad technical depth across web development, some native mobile work, and solid CI/CD experience, which lets him move across parts of a codebase without being siloed. I recommend Lee without reservation and am confident he would be a strong asset.”
