Technology · Node.js Development
Node.js, shipped responsibly.
REST and GraphQL APIs, background workers, webhooks, and middleware — written in TypeScript, deployed with health checks, and operated under observability.
Sheet 01 · Overview
JavaScript on the server, taken seriously.
Node.js gets a bad rap from poorly-written codebases — but well-structured Node applications are some of the most maintainable and operable systems we ship.
TypeScript everywhere. Validation at every boundary. Structured logging. Idempotent mutations. Background work that retries. Health checks. Graceful shutdowns. Observability dashboards that mean something. None of this is exotic — it is the floor.
Whether the engagement is a REST API powering a Vue or Remix frontend, a GraphQL layer in front of an aging legacy system, or a fleet of background workers eating webhook events — we have shipped it.

Sheet 03 · Process
How we build services.
- Phase 01
Contract
API surface, error taxonomy, auth model, and rate limits documented before implementation begins.
- Phase 02
Build
Typed services with validation at every boundary, integration tests covering the contract, and structured logging in place.
- Phase 03
Deploy
CI/CD configured. Health checks wired. Monitoring active. Rollback path documented.
- Phase 04
Operate
Retained ops: capacity reviews, security patching, dependency upgrades, and feature work.

Sheet 05 · FAQ
Questions, answered.
Which Node.js framework do you use?
Express for REST APIs and middleware. Fastify when performance matters. Nitro inside Nuxt projects. Plain Node for serverless handlers. We pick per workload — not per fashion.
TypeScript or plain JavaScript?
TypeScript everywhere by default. The maintenance and refactor leverage is worth the build-step overhead. JavaScript only when extending a legacy codebase that has not been converted.
Do you build APIs from scratch?
Yes. REST and GraphQL APIs with proper request validation, error taxonomy, structured logging, idempotency for mutations, and OpenAPI or GraphQL Code Generator documentation.
What about background jobs and queues?
BullMQ on Redis for most engagements. AWS SQS or Cloudflare Queues when the deployment is already in that ecosystem. Jobs always idempotent, retried, and observable.
How do you handle long-running processes?
PM2 or systemd for VM hosts. Containerized via Docker for orchestrated environments. Health checks and graceful shutdowns wired into the deployment.
