01 / The story

Three brands, one codebase. 465 documented API endpoints, 15+ live stations, role-based access across about 40 permissions.

A full stack admin platform covering NOC operations, quotations, contracts, ticketing, inventory, and reporting for a network of 15+ charging stations. I am the sole engineer on it: the database, APIs, dashboards, scheduled jobs, integrations, deployment, and production support are all mine. Under the hood: 465 documented API endpoints, role-based access control across about 40 permissions, SSE realtime updates, and soft-delete with recoverable trash on every entity.
