Full-stack engineer focused on multi-tenant SaaS, identity & access management, and platform infrastructure.
I build things end-to-end — from auth systems and storage abstractions to performance-critical frontend. I own problems, not just tickets.

Currently at Eximietas Design, shipping IAM pipelines, RBAC restrictions, SLA/OLA tracking, and a provider-agnostic storage middleware layer for a production SaaS platform.
