Work Experience

Principal Member of Technical Staff, MyAT&T Atlanta USA

Jun 2022 - Present

MyAT&T is the native app for managing AT&T wireless, wired, DirecTV and broadband accounts: network state, router reboots, extender install and repair, guest access, parental controls, Wi-Fi speed tests, bill pay and plan upgrades.

I lead the backend for Control Center, one of four primary tabs in the app. Since 2025 I have also directed a team of four engineers and two QA day to day while staying roughly 60% hands-on. I cut Control Center load time from about 15 seconds to under 2 through distributed caching, downstream call consolidation and payload optimization, and I own the novel work: service migrations, Kafka event pipelines, scheduled jobs, and monitoring across the team's APIs.

Principal Member of Technical Staff, AT&T Cell Booster Atlanta USA

Feb 2021 - May 2022

Cell Booster is a low-power small cell that extends AT&T LTE voice and data coverage into homes, apartments and small businesses with poor indoor signal, covering 3,000 to 15,000 sq ft.

Architect and lead Android engineer. I built the app from the ground up on MVVM with Jetpack components (view binding, ViewModel, Hilt, repository pattern, Retrofit) and shipped it to both stores. Features included OAuth authentication, device registration and customization, troubleshooting, granting and revoking access to the cell site, and performance monitoring. Ran concurrently with Smart Home Manager.

Principal Member of Technical Staff, AT&T Smart Home Manager Atlanta USA

Jan 2017 - Jun 2022

Smart Home Manager is a native app for managing a Wi-Fi mesh network: network state, router reboots, extender pairing and repair, guest access, parental controls, bandwidth management, speed tests, AR signal strength finding, and a virtual assistant for troubleshooting.

I started this project from scratch and owned its architecture end to end, designing it so new features could be added without structural rework. I worked in a dual senior Android and iOS role and led the launch on both stores, building the dashboard, device and network management, live agent chat, authentication, and an AI troubleshooting chatbot. Accessibility TalkBack support throughout.

Feb 2016 - Jan 2017

Digital Life is an IP-based security and home automation platform that lets customers monitor and control their home from phones, tablets and the web.

Android developer on the platform. I delivered Android Wear 1.0/2.0 support, the security alarm system and user-configurable custom routines, a dynamic device widget framework so future device UIs render automatically, and white-label build flavors for international locales. I also mentored new hires onto the team. I joined this product as an Apex Systems contractor in 2014 and converted to full-time AT&T in Feb 2016.

About Me

  • I build and lead backend systems at consumer scale. Today that means leading the backend behind a core section of the MyAT&T app and a team of six, splitting my time roughly 60/40 between engineering and leading.
  • The hands-on half is the work nobody has done before: microservice migrations, caching and performance architecture, Kafka event pipelines, monitoring and alerting. The other half is sprint planning, release management, stakeholder alignment, and surfacing hard problems early instead of at the release gate.
  • Before backend I spent six years on mobile architecture. I started Smart Home Manager from scratch and architected Cell Booster from the ground up, both shipped to iOS and Android.
  • I care a lot about code review as a discipline. I review everything my team ships, and I have spent the last year working out how to review AI-assisted code: what to trust, what to verify, and where the failure modes are.
  • Outside of work I build things. Three hackathon wins, a handful of side projects, and a running habit that keeps the rest of it honest.
