Hire MERN stack developers for your team in Germany

A MERN developer works across MongoDB, Express, React and Node.js. Look for someone who can trace a fault from a screen, through the API, to the data behind it.

• Data structureUse Mongoose schemas or MongoDB validation to stop inconsistent documents from accumulating in the database.
• API securityValidate inputs, handle errors, authenticate users with sessions or tokens, and check permissions on every route.
• React interfacesHandle loading, error and empty states, manage server data with a fetching library, and keep screens usable on phones.
• Reports and transactionsUse aggregation pipelines for dashboards and transactions for changes that must succeed or fail together.
• Shared definitionsKeep TypeScript types or validation schemas consistent across the front end and back end, so an API change is caught on both sides.

You work with developers who already contribute to our client projects. We include a lead who reviews code and keeps the work on track.

1. 01

   Choose capacity

   Hire full time, part time or for a fixed number of hours a month. The choice gives you a defined way to organise the work.

2. 02

   Join your workflow

   Developers work in your repository, tickets and stand-ups. We agree the hours of overlap with you up front.

3. 03

   Start with a real task

   We set up the environment, walk through the product and codebase, and use a small task that touches the main parts of the system.

4. 04

   Share the technical setup

   Give us your architecture overview, coding standards, branching and release process, plus instructions for running the project locally. We write down any gaps found during onboarding.

5. 05

   Control access

   Start with individual accounts and the permissions needed for staging. Add production access once the review process is in place.

A customer-facing product that stores or reads information on a user’s device needs to account for consent under § 25 TDDDG, unless the storage or access is strictly necessary for a requested service. We set up a consent banner for the relevant choices and keep strictly necessary access separate.

If we process personal data for you, we set up a processor contract and seek your prior approval before using further processors. For transfers to a country without an EU adequacy decision, the contract can include the European Commission’s standard data protection clauses as an appropriate safeguard.

A little preparation gives the developer real work to pick up and a clear route to approval.

• Rank the backlog or write a starting set of tasks with enough detail to begin work.
• Identify the skills and seniority you need, including any framework or legacy-system experience.
• Set your working hours, the overlap you need and who will answer the developer’s questions.
• Define doneagree review rules, expected tests, deployment and who approves the work.
