Building backends that scale and frontends that don't get in the way.
Most of what I work on lives in the unsexy but critical layer multi-tenant infrastructure isolation, provisioning pipelines, auth systems. The parts that have to be right before anything else matters.
Currently building TropicCrm
Current Build: Multi-Tenant SaaS Platform

◆ schema-per-tenant true isolation — no WHERE tenant_id scattered everywhere
◆ rbac at resolver permissions enforced before the data layer, not after
◆ stateless auth refresh token rotation — revokable, auditable, no sticky sessions
◆ provisioning pipeline schema creation, seeding, config as atomic steps
