Node.js Developer for Startup in Montreal
Sachin Sharma is a Node.js Developer in Montreal — Node.js backends that handle real traffic — event-driven, no
There are 10 lakh+ agencies, 5 crore+ "vibe coders," and 1 crore+ developers out there — and somehow you ended up on this page. That's not an accident, that's a genuine signal. I'm 21, and if you're on my website right now, you're already looking at someone better than most of what's out there. I'd genuinely prefer to talk to you directly rather than have you read through another page. Please feel free to call, message, or email — whichever works best for you.
Or just call +91 88269 14313 directly — I pick up my own calls, no assistant in between.Who is Sachin Sharma?

Node.js Technical Expertise
Architects Node.js backends using Express.js or Fastify with a clean layered architecture (routes → controllers → services → repositories), applying dependency injection for testability and separation of concerns. Implements BullMQ with Redis for reliable background job queues with retry logic, dead-letter queues, and worker concurrency control. Uses Drizzle ORM with PostgreSQL for type-safe database queries with migrations, connection pooling via pg-pool, and query optimization with EXPLAIN ANALYZE. Deploys on Docker containers with health checks, Prometheus metrics scraping, and Grafana dashboards for real-time observability in production environments.
Montreal Market Context
Montreal's world-renowned AI research corridor, gaming studios, and scaling SaaS companies.
IST is 9.5 hours ahead of EST — morning Montreal syncs are late afternoon/evening IST.
Why Hire for Node.js?
- Node.js skill: 90/100 — production API backends with Express.js, BullMQ, Redis, Drizzle ORM, and PostgreSQL.
- Built and deployed Node.js services using Docker with Prometheus monitoring and Grafana dashboards.
- BullMQ expertise: background job queues for email sending, image processing, and scheduled data sync — reliable at production scale.
- PostgreSQL + Drizzle ORM: type-safe database layer with migrations, connection pooling, and query optimization.
- Socket.io real-time backends: 86/100 skill level — used for live chat, notifications, and collaborative features.
- 1.5+ years building full-stack applications with Node.js backends in professional and project contexts.
- Redis experience: session caching, rate limiting (sliding window), pub/sub for real-time events, and BullMQ job persistence.
- REST API design: versioned routes, middleware chains, JWT auth with refresh tokens, and OpenAPI documentation.

How Node.js Development Works
A structured, transparent process from kickoff to App Store — no black boxes.
API Architecture
Route/controller/service/repository layers, define OpenAPI schema first, plan auth middleware (JWT/OAuth), and rate limiting strategy.
Database Design
Drizzle schema with proper indexes, foreign keys, and soft deletes. Migration strategy with drizzle-kit generate + push.
Background Jobs
BullMQ queues for async operations, worker concurrency tuning, dead-letter queue monitoring, and job progress tracking.
Observability
Prometheus metrics endpoint, structured JSON logging (Winston/Pino), Sentry error tracking, and Grafana dashboard setup.
Containerization
Multi-stage Dockerfile, docker-compose for local dev, health checks, graceful shutdown on SIGTERM, and production secrets via environment injection.
Node.js in Montreal — What Most Devs Miss
Node.js's event-driven, non-blocking I/O makes it ideal for Montreal-based SaaS products with high concurrency — it handles thousands of simultaneous connections on a single thread that would bring blocking languages to a halt.
BullMQ has become the de facto standard for Node.js job queues in 2024 — Bull.js is deprecated and BullMQ's TypeScript support + Redis 7 compatibility makes it the only viable choice for new projects.
Drizzle ORM is the fastest-growing Node.js ORM in 2024, outpacing Prisma in performance benchmarks while offering better TypeScript inference — the ecosystem has already started shifting.
Sachin Sharma vs. Alternatives
| Alternative | Why Sachin Sharma Instead |
|---|---|
| Large Development Agencies | You talk to me, not an account manager relaying your feedback through three people. When you say "change this," I'm the one changing it — same day, not next sprint. |
| Junior Freelancers | I've shipped real Node.js apps to real users — production-grade installations, not tutorial projects. You're not paying to be someone's first attempt. |
| Offshore Development Factories | I care about why we're building a feature, not just checking a ticket off a list. Every Node.js decision gets real product thinking, because it's my name on the work too. |
Proof Points
- Built production Node.js APIs used by real users in startup environments — not just tutorial CRUD apps.
- BullMQ + Redis job queue handling 1,000+ daily background tasks with automatic retry on failure and Slack alerting on dead-letter queue entries.
- Docker-containerized Node.js services with multi-stage Dockerfile builds, non-root user, and health check endpoints.
- Prometheus metrics middleware for Express — tracking p50/p95/p99 request latencies and error rates in Grafana.
- Drizzle ORM migrations with rollback support — zero-downtime schema changes using transactional DDL.
