Enterprise SaaS Platform — Node/Nuxt/MongoDB/GraphQL
Delivered production platform — largest single contract at $69K, 2,305 hours of deep architecture work.
Why this matters
Client needed a scalable enterprise platform with complex data relationships and real-time features.
My role: Full-stack architecture, API design, frontend build
Project notes
Problem Statement
The client needed a full enterprise SaaS platform built from the ground up. The existing solution was a collection of spreadsheets and manual processes that couldn’t scale past their current customer base.
Technical Approach
I designed and built the entire stack:
- Backend: Node.js with GraphQL API layer, handling complex data relationships between organizations, users, projects, and resources
- Frontend: Nuxt.js (Vue SSR) with real-time updates via WebSocket subscriptions
- Database: MongoDB with carefully designed schemas and indexes for query performance
- Infrastructure: Docker containers deployed on AWS with CI/CD pipeline
Key Decisions
Why GraphQL over REST: The data model had deeply nested relationships. GraphQL eliminated the N+1 query problem on the frontend and let the client team build new views without backend changes.
Why MongoDB: The document model matched the domain well — flexible schemas for different organization types, embedded documents for frequently-accessed related data, and aggregation pipelines for reporting.
Results
- Delivered over 18 months of continuous development
- Platform handled the client’s full customer migration
- 2,305 hours of deep, focused architecture work
- Largest single contract on Upwork at $69,140
