- **Work across the full stack** — data model, API contract, UI, and production behavior — contributing to domains as they move onto the modern stack. - **Recognize bad legacy patterns and don't repeat them** — read the existing Express/MongoDB and Backbone/React layers, understand where they fell short, and apply better practices in new development rather than carrying old habits forward. - **Design for scale within real constraints** — build solutions that scale even when they have to integrate with a rigid legacy system that can't be changed wholesale. - **Build on the modern stack** — NestJS modules (DI, guards, interceptors) and Next.js apps (App Router, server components, typed clients). - **Understand the strangler-fig approach** — how legacy and new run side by side, behind feature flags, with zero data loss and no downtime — and contribute to it without disrupting it. - **Model relational data carefully** — help move money-bearing/transactional data from documents into a normalized SQL schema with real constraints and safe migrations. - **Write tests as a default** — unit, integration, E2E. The suite is what lets the team move fast safely. - **Spot and flag problems** — the flaky test, the N+1, the missing index. Raise them clearly so they get prioritized, and pick them up when it makes sense. - **Use AI tooling efficiently** while understanding and standing behind every line that lands.
