Services - Express and Node APIs, built by a senior engineer.
Your frontend is ready but the backend is the bottleneck. Half-built endpoints, auth you don't trust, webhooks that silently drop, and a queue of integrations buyers keep asking for. We build the Express/Node API behind your product so the rest of it can ship.
What's included
- Design and build REST APIs in Express with input validation, consistent error handling, pagination, and rate limiting. Not just routes that return 200 and hope.
- Wire up real auth: session or JWT login, refresh tokens, password reset, and OAuth/social sign-in with Google, GitHub, or whoever your users actually use.
- Build the third-party integrations that keep stalling deals (Stripe, Slack, Twilio, S3, or any vendor API) with retries, idempotency, and webhook handlers that don't drop events.
- Stand up background jobs and queues (BullMQ/Redis) for emails, exports, and long-running work, so requests stay fast and nothing blocks the response.
- Add real-time features over WebSockets: live notifications, presence, or collaborative updates, with reconnect logic and auth on the socket, not just the happy path.
- Connect it all to PostgreSQL. Schema and migrations, the right indexes, transactions where money or state is on the line, and the N+1 queries hunted down.
Why on a subscription
Backend needs swing hard. One week a critical webhook is dropping events and costing you signups. The next, a customer won't sign until a specific integration ships. A flat $6,900/month with one task at a time means you reprioritize the second the work changes, and pause the month things go quiet. No salary to carry, no contract to renegotiate.
Frequently asked questions
- We already have a backend. Will you work in our existing Express app?
- Yes. You're working with a senior engineer who inherits codebases for a living. We match your structure, middleware, and conventions, send everything as PRs to your repo, and you review and merge. Nothing ships without your eyes on it, and revisions are unlimited if you want it done differently.
- Is this code-only, or do you run our servers too?
- Code-only. We build the API, the auth, the jobs, and the migrations, then hand it over as PRs. We're comfortable across AWS, Docker, and a plain VPS, so we'll wire up the deploy config and infra-as-code. But we don't take over ops or hold the pager for your production environment.
- A customer needs a specific integration to sign. How fast can you turn it around?
- Drop it at the top of your queue and it becomes the active task. Most tasks land in 48 to 72 hours. A larger integration spanning several tasks moves in that same priority order. You reprioritize anytime, so a hot deal always jumps the line.
