Digitally known as: gchriswill

Current Areas of Focus:

• Swift Across All Platforms
• AI Systems Infrastructure

A cross-functional and multi-disciplinary engineer specializing in team leadership, team productivity and efficiency, resource orchestration, systems and software architecture, AI systems infrastructure, end-to-end agentic SDLC workflows, and mobile app ecosystems.

I’ve held roles as Engineer 3, Engineer 4, Senior Engineer, Principal Engineer, and Software Engineer with a Swift specialization. I’ve also collaborated cross-functionally with teams responsible for developing Cloud Infrastructure Training Modules at Apple; the My Verizon app (5G Home); the My Disney Experience app (PhotoPass AR Tech); Verizon’s Chat Cloud Services, Digital Assistant, and My Fios app (Home Router and Network).

I’m passionate about developing innovative applications, solutions, and services on any platform and with any C-based programming language, although I prefer Swift. I also enjoy mentoring and guiding the next generation of engineers to improve team performance, productivity, and value; product quality; and system reliability.

My aspirations include becoming an engineering leader with a strong technical focus, hands-on skills and expertise, and enterprise business experience.
