Levelbrook is a senior software consulting practice across Rails, Python, and Node. For JavaScript and TypeScript teams, we ship Node.js backends, APIs, integrations, worker pipelines, and production fixes — billed corp-to-corp through Levelbrook LLC.
Some teams need Rails depth. Some need Python automation or AI tooling. Some need a Node.js and TypeScript backend engineer who can join an existing JavaScript stack and ship. Levelbrook covers that work too: APIs, integrations, worker pipelines, and the production plumbing around them.
The common thread is not a framework. It's senior backend judgment: clean boundaries, boring auth, observable jobs, careful data modeling, and code your team can maintain after the engagement ends.
Node engagements run corp-to-corp through Levelbrook LLC, with MSA, SOW, mutual NDA, and a COI (GL + Professional Liability, $1M / $1M) ready on day one. Work can be scoped as a project or run as staff augmentation inside your existing team.
Express, Fastify, NestJS, or your existing Node framework — typed, tested, and organized for handoff.
REST, GraphQL, OAuth, webhooks, partner APIs, and the retry/idempotency logic that keeps integrations dependable.
Background workflows with BullMQ, Redis, SQS, and clear failure handling instead of mystery retries.
Observability, performance fixes, deployment cleanup, and test coverage around the paths that matter.
Node.js and TypeScript backend work are part of the Levelbrook consulting practice alongside Rails and Python. Rails is a service area, not the whole company.
Express and Fastify are common, NestJS is fine when a team already uses it, and plain TypeScript services are often the right answer for smaller internal systems.
Yes. Staff augmentation is often the shape: join the sprint, pick up backend tickets, review PRs, and ship within the team's current workflow.
Yes — OAuth, partner APIs, webhooks, retries, idempotency, audit logging, and observability are exactly the kind of Node backend work Levelbrook takes on.
Corp-to-corp through Levelbrook LLC — hourly for ongoing staff augmentation, fixed-scope for defined builds. MSA / SOW / NDA / COI ready on day one.
