Principal Engineer · The Aspen Group · Chicago

Xinjiang Shao I build healthcare platforms that can't afford to fail — and grow the teams behind them.

Principal Engineer at The Aspen Group, where I lead platform architecture across five healthcare brands and a 30+ engineer organization. Earlier: grocery e-commerce for 20M+ weekly shoppers, and a sports-tech platform built from scratch.

❝What colleagues say

At The Aspen Group (TAG), he went even further by helping architect and build a brand-new platform and onboarding all company brands in about a year. … For perspective, I’ve seen other organizations take more than a year just to bring one brand live. … Any engineering organization would be lucky to have Xinjiang leading its most critical technical initiatives.

— Jen Anderson, PhD · Founder, Astrix 8 Partners

Xinjiang was one of the best developers at our company--he was always the go-to person for our design team when we had questions, simple or complex. We knew he'd always be willing to work with us to find the answer. I'd love the opportunity to work with him again in the future.
