MEAN is a web stack of MongoDB, Express, Angular and Node.js, with JavaScript or TypeScript in every tier.
15+ years of team experience · Salesforce Select Partner · Delaware and Sydney
MEAN stack development for real-time apps and products that change fast.
We build and take over applications on MongoDB, Express, Angular and Node.js, keep every tier on a supported release, and supply MEAN stack engineers who join your team.

New to the MEAN stack?
What is the MEAN stack?
MongoDB stores data as JSON-like documents, which suits catalogs, dashboards and data whose shape changes often.
Each part has its own release and support cycle, so upgrades are planned tier by tier.
Where you are starting from
Where are you with the MEAN stack?
What state is your MEAN application in today?
- Path 01Not built yet
A new MEAN build
You need a SaaS product, dashboard or MVP and want one language across the stack.
- Data model agreed before code
- Current releases in every tier
- Tests and pipeline from the first sprint
- Path 02Built by a team that left
Taking over an application
A MEAN app runs in production and the people who built it have moved on.
- Code, database and hosting review first
- Deploy, backup and restore steps written down
- Fixes ranked by risk
- Path 03Several tiers out of date
Upgrading or modernizing
It works, but runs on MongoDB 6, Node.js 20, Express 4 or an old Angular.
- Each tier checked against its support dates
- Upgrades done in tested steps
- Self-hosted MongoDB moved to Atlas if it helps
A MEAN application on supported releases in every tier, with tests, documentation and a team that can run it
What we do
What do our MEAN stack development services include?
One team across the database, the API and the Angular front end.
New MEAN applications
01SaaS products, MVPs and internal tools built from a written design.
Real-time dashboards
02Live views over streaming and IoT data that update without a refresh.
APIs on Express and Node.js
03Secured, documented APIs with Passport and Helmet in place.
MongoDB data modeling
04Schemas, indexes and Mongoose models designed for how the app reads.
Tier-by-tier upgrades
05MongoDB, Express, Angular and Node.js moved to supported releases.
Testing
06Jest unit tests and Playwright end-to-end tests in your pipeline.
Salesforce integration
07The Node.js tier connected through the Salesforce REST, Bulk and Pub/Sub APIs.
Team extension
08MEAN stack engineers who work in your repos, rituals and tools.
Technology
The MEAN stack we work with
Four tiers, each with its own tools and support dates.
- Angular
- RxJS
- Angular Material
- Express 5
- Node.js
- NestJS
- Passport
- Helmet
- MongoDB 8.0
- MongoDB Atlas
- Mongoose
- Jest
- Playwright
- Docker
MEAN stack upgrades
Which parts of our MEAN stack need upgrading?
MongoDB 6.0 support ended in July 2025 and Node.js 20 in April 2026. Angular 20 reaches end of life on November 28, 2026.
TodayMongoDB 5 or 6, Express 4, Node.js 20
- MongoDB 8.0
Upgrade the database
MongoDB 8.0 is supported to October 2029; 7.0 ends in August 2027. We step through versions with backups and tests at each stop.
Best for every app on MongoDB 6 or older.
- MongoDB Atlas
Move to a managed database
Self-hosted MongoDB moved to MongoDB Atlas, with backups, monitoring and upgrades handled by the service.
Best when nobody on the team wants to run the database.
- Express 5 on Node.js 24 or 26
Update the API tier
Express 5 is current and Express 4 is still patched. Routes and middleware moved to 5 on Node.js 24 (to April 2028) or 26 (to April 2029).
Best done together, since both touch every route.
How we work with you
How can we work together on the MEAN stack?
Three ways to engage. Each starts with a written proposal agreed before work begins.
- Fixed-scope project
A defined MEAN deliverable, built and handed over.
- We direct the work against agreed milestones
- Priced per milestone in the proposal
- Working code, tests and documentation
- Fits an MVP, an upgrade or a rescue
- Dedicated team
A full-stack team that runs your product with you.
- Our lead runs delivery, you set priorities
- Billed on a monthly plan
- Front-end, back-end and testing as one unit
- Fits a SaaS product without an in-house team
- Team extension
MEAN stack engineers added to the team you already run.
- Your managers direct the day-to-day work
- Billed monthly for each engineer
- Vetted engineers; we handle employment and replacement
- Fits a backlog bigger than your current team
How it runs
How does a MEAN stack engagement start?
Five steps from the first call to delivery.
- Brief
- Free 60-minute review of your application
- Goals, constraints and access agreed under NDA
- Match or design
- Engineers matched and interviewed by you
- Or a scope and milestone plan written
- Start
- Database, repos and environments set up
- Codebase walkthrough and a first task
- Build and review
- Sprints with code review on every change
- Tests and a demo each sprint
- Hand over or continue
- Runbooks and handover sessions
- Or a monthly plan for support
Cost and timing
What it costs and how long it takes
The review is free
A 60-minute architecture review of your MEAN stack application setup, with a written plan you keep.
A fixed-scope proposal first
Before any work starts you get a written proposal: a fixed-scope project with milestones, or a monthly plan. You approve it, or you do not.
Timing follows scope
How long it takes depends on what is in scope. The proposal states the milestones, so you see the timeline before you commit.

Frequently asked questions
MEAN stack development, answered.
Straight answers about what we build, MEAN stack upgrades, how engagements work and how our engineers join your team.
Real-time dashboards, content and catalog platforms, IoT data apps, multi-tenant SaaS products, collaboration tools and MVPs that need to change quickly.
MongoDB 6.0 ended in July 2025 and Node.js 20 in April 2026. Angular 20 ends on November 28, 2026. MongoDB 8.0 runs to October 2029 and Node.js 26 to April 2029.
Three ways: a fixed-scope project with milestones, a dedicated team on a monthly plan, or engineers who join your team. Each starts with a written proposal agreed before work begins.
Yes. They work in your repos, tools and sprint rituals, and your managers direct the day-to-day work. We handle employment, and the replacement terms are written into the contract.
Each engineer passes a technical interview across MongoDB, Node.js and Angular, a practical coding exercise and a review by a senior engineer. You interview them and decide before anyone starts.
Yes. The Node.js tier connects through the Salesforce REST, Bulk and Pub/Sub APIs, often with jsforce, a community library, so the Angular front end never holds Salesforce credentials.
We work from hubs in Delaware and Sydney and deliver remotely worldwide on your business hours. The agreed overlap with your team is written into the contract.
