Join us at the NRTCCA Conference in Phoenix, Arizona. This event is a great opportunity to see 10-20 in action at our booth.
I'm Lee 👋 by day, I'm a software developer. I've worked in both startup and enterprise environments, mostly as a web developer while dabbling in mobile apps.
By night, I'm co-founder / CTO of 10-20.io, a location sharing communication platform for first responders and founder of DFW Code & Coffee, a meetup group and non-profit hosting networking events for programmers in the Dallas/Fort Worth metroplex.

A Senior Dev On Your Team
Web and mobile development, contracted by whatever makes sense for your org. Startup pace with enterprise experience: code review, CI/CD, and documentation that outlives the contract.
“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.”
