About
From the front line
to the code.
I started in customer support at Ubiquo Labs — resolving 1,300+ incidents for banking and government clients with 98%+ satisfaction. That front-line experience gave me something most engineers don't have: an obsession with how things feel to the user.
Today I'm a Semi-Senior Engineer at Walmart CAM — building cutting-edge full-stack TypeScript systems at enterprise scale via Babel Group. Before that, I spent two years at Ubiquo Labs architecting microservices that processed millions of daily SMS transactions, built a multi-language SDK suite that cut client onboarding from 2 weeks to 3 days, and created automation that eliminated 80% of support tickets. Currently pursuing my Master's in Information Security.
