Node.js consulting for backends that move data
DEV3LOPCOM, LLC is an Austin, Texas consultancy that builds Node.js services for a living: REST and GraphQL APIs, webhook receivers, background workers, real-time WebSocket layers, and the integration glue between SaaS tools, databases, and warehouses. We are 100% onshore, and the engineers on the call are the engineers in the repo.
Node.js is our default tool for integration-heavy backends because that is where it earns its keep — lots of concurrent I/O, JSON in and JSON out, one language across the stack. At Lever, our work spanned 11 Python apps alongside 282 SQL queries and 186 Tableau workbooks in an automation effort that saves roughly 22,000 hours a year; we are pragmatic about runtimes, and when Node is the right fit we say so with specifics, not fashion.
How an engagement runs
Assess. For existing apps we profile before we opine: event-loop lag, memory growth, slow queries surfaced through APM or simple instrumentation, dependency audit, and a read of how the app is deployed. Most “Node is slow” complaints turn out to be an unindexed query or a synchronous call blocking the loop.
Design. We propose the smallest architecture that handles your load. Express or Fastify over a heavy framework unless you need the framework. Postgres before exotic datastores. Queues (BullMQ, SQS, Pub/Sub) when work genuinely needs to leave the request path.
Build. TypeScript by default, tests around the behavior that pays your bills, CI/CD from the first week, structured logging so production is debuggable. We deploy to whatever you run — containers, Cloud Run, Lambda, ECS, or a plain VM — and we handle the cloud infrastructure side when nobody else owns it.
Hand off. Documentation, architecture notes, and pairing time with your developers. The codebase should feel like theirs, because it is.
Problems we fix
- APIs that fall over under concurrency because blocking work sits on the event loop — moved to workers or queues.
- Memory leaks that force nightly restarts. We find them with heap snapshots instead of guessing.
- Callback-era codebases nobody wants to touch — incrementally migrated to async/await and TypeScript without a rewrite freeze.
- Webhook integrations that drop events silently. We add signature verification, idempotency, retries, and dead-letter handling.
- Node services that feed dashboards and warehouses but do it fragilely. Data movement is our home ground — see our data pipeline consulting services.
Why dev3lop
Our founder is a former Tableau Software Professional Services consultant, and the practice has shipped production work for GoPro, ExxonMobil, Nielsen, and Lever. That history means our Node.js services are built with operations in mind: monitored, documented, and boring to run. If the project includes a frontend, our web development services cover React and modern frameworks so one team owns the whole stack.
