"I build the systems that global teams rely on — from Okta SSO to production incident response across 100+ countries."
[02] About
Systems thinker,
Problem solver.
I'm a Full Stack Engineer with 4+ years building enterprise authentication systems and MERN SaaS applications at ResMed, a global healthcare company operating in 100+ countries.
I specialize in Okta SSO/MFA infrastructure, Redis-optimized backend APIs, and end-to-end feature delivery — from Figma wireframes to production deployments. I've resolved 25+ global production incidents across Germany, UK, Japan, APAC, and LATAM, all without escalation.
Currently open to Senior Full Stack Engineer roles in Hyderabad or remote. I bring production-proven systems thinking to every team I join.
