"I build the identity systems that global teams rely on — from Okta SSO and CIAM platform architecture to production incident response across 100+ countries."
[02] About
Systems thinker,
Problem solver.
I'm a Full Stack Engineer with 4+ years of professional experience specializing in authentication, identity management, and scalable SaaS platforms at ResMed, a global healthcare company operating in 100+ countries.
I specialize in Okta SSO/MFA infrastructure, multi-tenant CIAM architecture, Redis-optimized backend APIs, and end-to-end feature delivery. I've resolved 25+ global production incidents across Germany, UK, Japan, APAC, and LATAM, all without escalation. Selected as one of three core engineers architecting ResID Unified SignIn 2.0 — ResMed's first unified CIAM platform.
Currently open to Senior Full Stack Engineer roles in Hyderabad or remote. I bring production-proven systems thinking to every team I join.
