Cloud-Native Corporate Portal
100% Serverless architecture that tied infrastructure costs to adoption growth, achieving $125,000 USD ROI in 4 months through automation of critical processes (Sales, Travel Expenses, Human Capital).
The Problem
Digital transformation blocked by resistance to change and high financial risk. A traditional architecture implied high fixed costs without adoption guarantees. Success needed to be demonstrated early with a strategy that tied costs to growth.
The Solution
I designed a pure Serverless architecture (Lambda, DynamoDB, Aurora) with a Headless frontend in Nuxt.js deployed with AWS Amplify. 'Pay-per-Adoption' model where elastic infrastructure keeps costs minimal in the initial phase and scales only with project success. High-impact modular delivery to validate value quickly.

The Challenge: Resistance to Change and High Investment Cost
Slow Adoption
Technology needed to be a showcase to evangelize other areas, making initial success and quickly delivered value critical.
Financial Risk
A traditional architecture implied high fixed infrastructure costs from the start, without guarantees of full adoption. A strategy that tied costs to adoption growth (ROI) was needed.
The Architectural Solution: Serverless as a Business Strategy
Pure Serverless Architecture
I designed a portal based on a Headless and modular architecture, using Nuxt.js for the frontend (deployed with AWS Amplify) and modern databases like DynamoDB and Aurora for the transactional backend.
'Pay-per-Adoption' Model
The Serverless approach (Lambda, DynamoDB) ensured elastic infrastructure. In the initial low-adoption phase, infrastructure costs were minimal. As adoption grows, the infrastructure budget also grows, funded by the project's own success.
Modular Value Delivery
We launched high-impact modules (Travel Expense Settlement, Sales Processes) in short cycles, demonstrating tangible value to evangelize the rest of the organization and ensure project expansion.
The Impact and Return on Investment (ROI)
Proven ROI in 4 Months
In the first 4 months, the portal generated an estimated annual savings of $125,000 USD thanks to automation of manual processes in Sales and Human Capital. This validated the investment and funded future modules.
Sustainable Scalability
The architecture is prepared to scale elastically and financially, ensuring that adoption growth doesn't generate unexpected spikes in the IT budget.
Adoption Culture
The initial success of the Travel Expenses and Sales modules served as the necessary proof of concept to eliminate resistance to change and accelerate digital transformation in other areas.
