Hire MERN stack developers for your team in the United States

Look for someone who can explain how the data, API and interface fit together. Ask to see how they make changes safely across those boundaries, particularly when a product already has users and an established codebase.

• Data modellingDesign MongoDB documents around the app’s reads, choose where to embed or reference related data, and index common queries.
• Database validationUse Mongoose schemas or MongoDB schema validation to keep documents consistent as new features are added.
• API developmentBuild Express routes with input validation, error handling, authentication and permission checks on every route.
• Reports and transactionsUse aggregation pipelines for dashboards and transactions when related changes must succeed or fail together.
• Shared checksShare types or validation schemas between front end and back end so an API change is caught on both sides.

You direct the work through a shared backlog. We provide a lead who reviews code and keeps the work on track, while you retain control over priorities and review them with us regularly.

1. 01

   Choose capacity

   Hire developers full time, part time or for a fixed number of hours a month, according to the work you have ready.

2. 02

   Join your workflow

   Developers use your repository, tickets and stand-ups, with working overlap agreed before they start.

3. 03

   Start with real work

   Set up the environment, walk through the product and codebase, and choose a small task that touches the main parts of the system.

4. 04

   Control access

   Begin with individual accounts and the permissions needed for staging; add production access once the review process is in place.

5. 05

   Review early

   Check code from the outset to establish standards and catch misunderstandings before they spread through the codebase.

If your organisation is a HIPAA covered entity and the work gives a business associate access to protected health information, the written agreement needs to document safeguards. We set up individual developer accounts so access can be audited and removed; agree the information each account needs before granting it.

Financial institutions covered by the FTC Safeguards Rule need service-provider safeguards in their contracts and periodic assessments. Agree those safeguards with us before access to customer information, then arrange how they will be assessed as the work continues.

Give the developer enough context and decision-making support to start on useful work.

• A ranked backlog or a set of clearly described starting tasks.
• Your working hours, the overlap you need and the person who will answer questions.
• A definition of done covering review rules, tests, deployment and approval.
• An architecture overview, coding standards, branching and release process, plus instructions for running the project locally. Record any gaps found during onboarding.
