Sanjay Singh

Hi, I’m Sanjay Singh! Currently working as Staff Software Engineer at LinkedIn. I build scalable, reliable, and secure distributed systems, and I love turning complex infra problems into simple, resilient solutions.

What I’m focused on

  • Kubernetes platform engineering (controllers, schedulers, developer tooling)
  • Reverse proxies, service discovery, load balancing
  • Zero Trust security: mTLS authorization & SSO authentication
  • Access control models, cloud-native architectures, and performance at scale

Recent highlights

  • Trust Bridge — reverse proxy + mTLS + SSO for enterprise Zero Trust access control
  • Enabled migration of stateless apps to Kubernetes with optimized routing, scaling, and policy enforcement
  • Designed/operated LinkedIn’s edge/reverse proxy for incoming traffic, including dynamic routing and client-side load balancing
  • Rolled out mTLS authorization & SSO across production traffic

Connect

I’ll use this space to publish notes and deep dives on Kubernetes, HAProxy, networking, and security.
If you’re into similar problems, stick around — more posts are coming.
