I'm a software engineer at Allegion (Schlage) with 4+ years of production backend and API experience, specializing in application security — authentication/authorization hardening with mTLS/X.509 and OIDC/JWT/JWKS, automated security testing, and incident response. I build and secure partner-facing APIs on Azure with event-driven architectures. Originally from Hefei, China; now living and working in Colorado, USA.

Before that, I spent two years doing NLP/ML research at CU Boulder. Outside of work I shoot photos — see my photography site at jaynlper.pages.dev — and I'm currently reading AI Engineering by Chip Huyen, with chapter quizzes I write along the way.
