Project Overview:

The app will give trade customers 24/7 self-service access to full product range while equipping the sales team with modern tools. It will replace much of the current manual process (phone, email and brochure-style website) with a professional, efficient mobile experience.

Language & Framework:

• TypeScript (advanced) — strict typing, decorators, async patterns
• Node.js — runtime fundamentals, event loop
• NestJS — modules, DI, guards/interceptors; modular-monolith → microservices design

Data:

• PostgreSQL relational modelling for a transactional commerce domain
• Transactions / ACID / concurrency control
• Postgres full-text search + GIN indexes
• ORM + migrations — Prisma, TypeORM, or Drizzle

Architecture:

• DDD / microservices extraction patterns — bounded contexts, module seams for later service extraction

Security & Auth:

• OAuth2 / OIDC, JWT, token lifecycle

Async Processing:

• SQS workers — retries, dead-letter queues
• EventBridge scheduled jobs
