Hire talent · Back end

Hire MongoDB developers who stay after the database goes live.

Senior engineers who join your repo, your sprint and your standups. They design the data model, write the aggregation pipelines and tune the slow queries, then stay to run what they built rather than handing it over and leaving.

What they do

Hire MongoDB developers who stay after the database goes live, end to end.

Document schema design

We model your documents around how the application actually reads and writes, deciding what to embed and what to reference. Get this wrong and every query after it is a workaround.

Aggregation pipelines

Reporting, roll-ups and lookups written as aggregation stages rather than pulled into application code. We keep pipelines readable, tested against real data volumes, and documented so your team can change them.

Indexing and query performance

We read the slow query logs, check the execution plans and add compound indexes that match your query shapes. Then we remove the indexes nothing uses, because each one costs you on every write.

Atlas setup and operations

Cluster sizing, replica sets, automated backups, alerting and restore drills, on MongoDB Atlas or a self-hosted deployment. A backup you have never restored from is not a backup.

Migrations and version upgrades

Moving off a relational database, splitting a collection or stepping through major MongoDB versions, run as staged migrations with a rollback path and no unplanned downtime.

Application and AI integration

Wiring MongoDB into Node, TypeScript and Python services through the official drivers, and into retrieval for AI agents and copilots using Atlas Vector Search where it fits.

How it runs

Plan. Build. Run.

01

A 30 minute call

We ask what you are building, what your data looks like now and where it hurts. You leave knowing whether MongoDB is the right store for it, even if the answer is that it is not.

02

Scope, timeline and price

You get a fixed scope with a named engineer, a start date and a price before any work begins. If the work is too vague to scope honestly, we say so and propose a short paid discovery first.

03

Embed and build

Your engineer joins your repo, your ticket tracker and your standups. Work goes through your review process, with schema changes and index additions written down as they land.

04

Run it after launch

When it is live you can keep the engineer, move to our managed retainer, or take it fully in house with the documentation and handover to do that properly.

Why infoloop

We do not hand over and leave.

  • We stay after launchMost engagements end at handover. Ours can carry on as a managed retainer: monitoring, fixes against agreed response targets, security updates and a monthly report on what changed.
  • Senior engineers, matched to the workYou meet the person before anything starts and you keep the same person throughout. No bench rotation, no CV pile to sift through, no juniors billed as seniors.
  • Fixed scope and a fixed priceBefore we start you get a written scope, a timeline and a number. Changes are agreed and priced separately rather than quietly absorbed into an open-ended hourly bill.
  • Your code, your cluster, your accessEverything lives in your repository and your MongoDB account from day one. Credentials stay yours. Nothing we build depends on us keeping a login.
  • Built to be handed overSchema decisions, index rationale and migration steps are documented while the work happens. Your in-house team can pick it up whenever you want them to.

What you get

Every engagement includes these, in writing, before work starts.

  • A documented data model covering every collection, field and relationship
  • Index definitions with the query each one exists to serve
  • Aggregation pipelines committed to your repository, not pasted into a console
  • Migration scripts with a tested rollback path for each step
  • Backup, restore and alerting configured in your own MongoDB account
  • A handover pack your in-house engineers can work from without us

Who this is for

Three situations where this is the right call.

Your queries got slow as the data grew

The app was fine at ten thousand documents and is painful at ten million. You need someone to read the execution plans, fix the indexes and reshape the collections causing it, without stopping the roadmap for a rewrite.

You are moving off a relational database

The relational schema no longer matches how the product works, and nobody on the team has modelled documents before. You want someone who has, working alongside them, rather than a consultant who hands over a diagram and leaves.

You need MongoDB depth your team lacks

Your engineers are strong but nobody owns the database. You want one senior person embedded for a defined stretch to set the patterns, unblock the work and leave the team able to carry on without them.

Questions

What buyers ask us first.

What does it cost to hire a MongoDB developer through infoloop?
We do not publish a day rate, because the price depends on the seniority the work needs and how long you need it. The shape is always the same: a 30 minute call, then a written scope with a fixed timeline and a fixed price before anyone starts. Longer engagements are priced monthly per person, and a managed retainer after launch is priced separately against what we keep live. If the work is too vague to scope honestly, we will say so and propose a short paid discovery rather than guess at a number you would end up arguing about later.
Can your engineer work in our existing repository and process?
Yes, that is the normal arrangement. The engineer joins your repository, your ticket tracker, your Slack or Teams and your standups, and their work goes through your code review and release process like anyone else's. We do not run a parallel project in our own tooling and drop a zip file on you at the end. Schema changes, index additions and migrations are committed as code with the reasoning written down, so your team can see what changed and why without having to ask us.
Do you work with MongoDB Atlas or self-hosted deployments?
Both. Most teams are on Atlas, and we work inside your own Atlas account rather than ours, so the cluster, the billing and the credentials stay with you. That covers cluster sizing, replica sets, automated backups, alerting and restore drills. If you run MongoDB yourself, on your own servers or in your own cloud account, we take that on as well. We are not resellers and have no incentive to push you onto a larger cluster than your workload actually needs.
What happens after the database work is live?
Two options, and you pick. You keep the engineer on and carry on building, or you move to our managed retainer: monitoring, fixes with agreed response targets, security and version updates, small improvements and a monthly report of what changed. This is the part most engagements skip. A database nobody watches drifts. Indexes stop matching the queries, backups quietly fail, a version reaches end of life. If you would rather run it in house, you can, and the handover pack is written for exactly that.
How do we know the engineer is right before we commit?
You meet them before anything is signed. We put forward a named person with the relevant background, you talk to them, and you can ask for a different match. Once started, that is the person you keep: no bench rotation, and nobody swapped out mid engagement without agreeing it with you first. If it is not working in the first fortnight, say so and we will replace the person or stop, rather than running down a contract neither side wants.
Is MongoDB the right database for what we are building?
Sometimes not, and we will tell you on the call. MongoDB suits variable or nested documents, fast iteration on schema, high write throughput, and workloads where you read whole objects rather than joining across many tables. It is a poor fit for heavily relational data with strict multi-table consistency needs, or for reporting that is really a pile of joins. Plenty of systems are better served by Postgres, or by both with a clear boundary between them. If the honest answer is that you do not need MongoDB, that is what you will hear.

Tell us what your data is doing. We'll bring the engineer.

One 30 minute call to look at your collections, your queries and what is hurting. You leave with a scope, a timeline and a price, and an honest view on whether MongoDB is the right tool for the job.
