Hi there, I'm Kevin Langley Jr!👋
Senior Software Engineer · Channels & Partnerships @ 1Password
I build the MSP (Managed Service Partner) partner platform at 1Password, on the Channels and Partnerships team.
These days my focus is mentoring engineers into technical leadership and shaping broader technical direction and architecture.
On the side I ship Domnr, domain intelligence for DNS, uptime, and critical changes across providers, and Slatewave, one consistent palette across 31 developer tools.
Based in Gainesville, Florida with my two kids (Kevin and Kately), four dogs (d00dle, Scout, Nugget, and Zelda), and our cat, Benji.
Open to mentoring, advising, and building something new together.
