Fullstack Developer (Node.js / NestJS / React) 1500​-​3000 USD

Salariu: $1,500 - $3,000 USD (negociabil în funcție de experiență)
Tip: Full-time
Stack: NestJS, TypeScript, Drizzle ORM, PostgreSQL, Turborepo, Redis, React

Despre Proiect
Construim o platformă CRM modernă pentru industria turismului, folosind arhitectură multi-tenant și monorepo. Platforma servește multiple branduri cu date izolate și scaling independent, dar codebase unificat.

Ce face platforma unică:

• Multi-tenant architecture (schema separată per brand)
• Monorepo cu Turborepo (shared packages, type-safe)
• Integrări API multiple (flight search APIs, tour operator APIs, messaging APIs)
• Real-time features (Redis, BullMQ)
• Background jobs (email, SMS, booking processing)
• Type-safe end-to-end (TypeScript + Drizzle ORM)

Stack Tehnologic

Backend Core

• NestJS - Framework modular cu dependency injection, decoratori, guards, interceptors
• TypeScript - Strict mode, type safety pe întreg stack-ul
• Drizzle ORM - Type-safe queries, migrations, relations, multi-tenant support
• PostgreSQL 15+ - Multi-tenant cu schema separată per brand
• Redis - Caching, session management, real-time features
• BullMQ - Background jobs (email sending, SMS, report generation, API sync)

Arhitectură & Infrastructure

• Turborepo - Monorepo cu intelligent caching, shared packages
• Docker - Containerization pentru development și deployment
• CI/CD - GitHub Actions pentru automated testing și deployment
• REST API - Clean architecture, versioning, rate limiting
• Third-party APIs - Flight search APIs, tour operator APIs, messaging APIs, payment gateways
• Webhooks - Incoming/outgoing webhook handling

Responsabilități

• Design și implementare API-uri RESTful moderne (NestJS modules, controllers, services)
• Implementare business logic complexă (bookings, payments, lead management)
• Design și implementare sistem multi-tenant robust
• Integrare servicii externe (third-party APIs, webhooks)
• Optimizare performanță (query optimization, caching strategies, database indexing)
• Design schema database (Drizzle ORM schemas, migrations)
• Background jobs design (email queues, sync jobs, scheduled tasks)
• Code review și mentenanță codebase
• Testing (unit, integration, E2E)

Cerințe (Must Have)

• Experiență solidă Node.js (3+ ani)
• Experiență practică NestJS (1+ ani) - modules, dependency injection, decorators
• TypeScript avansat - Generics, utility types, type inference
• PostgreSQL - Query optimization, indexing, transactions
• REST API design - Best practices, versioning, error handling
• Arhitectură backend - Design patterns (Repository, Service Layer, Factory)
• Code quality - Clean code, SOLID principles
• Problem solving - Abordare practică, rezolvare eficientă

Nice to Have

• Drizzle ORM - Sau ORM-uri similare (Prisma, TypeORM)
• Turborepo / Monorepo - Experiență cu monorepo-uri (Nx, Rush, etc.)
• Redis - Caching strategies, pub/sub
• BullMQ / Bull - Background job processing
• Docker - Containerization, docker-compose
• CRM systems - Sau sisteme B2B complexe
• Multi-tenant architecture - Sau sisteme multi-company
• Payment integrations - Stripe, PayPal, etc.
• CI/CD - GitHub Actions, GitLab CI, etc.
