📋 Description

• - **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.

🎯 Requirements

• - 4+ years shipping production full-stack • - Strong TypeScript front and back • - NestJS (or deep Express/Fastify w/ DI grasp) • - Next.js/React (hooks, App Router, SSR/CSR) • - PostgreSQL or MySQL (schema, indexing, transactions, migrations) • - An eye for distinguishing good patterns from bad legacy ones • - Ability to design scalable solutions that fit within an existing, rigid system • - Testing discipline (Jest, Playwright/Cypress, Supertest) • - API design (REST, auth, backward-compatible evolution) • **Bonus: ** • - Experience migrating off a legacy code • - Fintech/payments/ledger • - Message queues (RabbitMQ/SQS/Kafka) • - MongoDB/Mongoose Aggregation • - AWS/Docker/Kubernetes/CI • - Deliberate AI-agent use in production workflows
