Business applications
Connected screens and APIs for workflows built around document-shaped records.
MEAN Stack Development
Applications combining MongoDB, Express, Angular and Node.js, with one coherent contract from browser forms to persisted documents.

Edit a configurable request
Capability Example
A portal user updates a request with optional fields and nested items.
Illustrative data. Nothing is sent to an external system.
Example workspace1 / 3
Typed request
1Request: R-17
2Optional fields validated
3Expected revision: 4
Check field rules in the Angular form and again in the API.
MongoDB update
1Current revision: 4
2Nested items updated
3New revision: 5
Update the document only if its expected revision still matches.
Browser record
1Canonical response received
2Revision: 5
3Form reflects saved values
Return the canonical saved record to the client.
A consistent request revision or a conflict response that preserves the user's draft.
Follow the record through the next step
Connect the browser, API and document model.
Customer portals
Account and request management with controlled access to each record.
MEAN maintenance
Upgrade frontend and backend dependencies while preserving data compatibility.
A complete feature across the MEAN stack.

Share types without blurring responsibilities.
Data model
Choose document boundaries and indexes from actual query and update patterns.
Stack compatibility
Agree framework versions and deployment ownership across all four layers.
Questions before we start.
Does MEAN include AngularJS?
Modern MEAN commonly uses Angular. An existing AngularJS-based stack needs its own compatibility and migration plan.
Must every product use MongoDB?
No. If relational constraints are a better fit, a different full-stack architecture may be more appropriate.
Bring your starting point.
Bring the core record structure, main queries and any existing MEAN repositories.
