Personal Portfolio Website

Welcome to the repository of my personal portfolio website, www.arnaldocisneros.com. This project showcases my technical skills, professional achievements, and certifications in software development and cloud computing. It is built using modern technologies like React and TypeScript, while leveraging multiple AWS services for hosting, scalability, and seamless integration.

This platform is designed to be a highly efficient, serverless, and globally available application, optimized for speed and reliability, while ensuring secure management of resources.

Key Features

1. Built with React and TypeScript

The frontend is developed using React to create reusable, dynamic components for a smooth user experience.
TypeScript provides type safety and enhances code readability, reducing bugs and improving maintainability over time.
A fully responsive design ensures compatibility across all devices, including desktops, tablets, and mobile phones.

2. Deployed with Global Reach Using AWS Services

S3 with CloudFront:
Static files are hosted in an Amazon S3 bucket, and the website is delivered globally using AWS CloudFront for low-latency access and enhanced security through HTTPS.
Route 53 for Domain Management:
The custom domain www.arnaldocisneros.com is registered and managed through Route 53, ensuring reliable DNS resolution with minimal downtime.

3. Continuous Integration and Deployment (CI/CD)

The project uses AWS CodePipeline, CodeBuild, and CodeDeploy to automate the build and deployment process.
Every code change triggers the pipeline, ensuring faster iteration and reducing manual deployment errors.
Logs and performance metrics are continuously monitored to improve and scale the application efficiently.

4. Serverless Backend

AWS Lambda & API Gateway:
The backend logic is built with AWS Lambda for event-driven, serverless execution, and an API Gateway securely handles client requests.
DynamoDB for Data Storage:
User data and application content are stored in a DynamoDB database, enabling high scalability and low-latency data retrieval.
Secrets Manager for Sensitive Information:
Application secrets, such as API keys and database credentials, are securely managed using AWS Secrets Manager, ensuring data integrity and confidentiality.

5. Infrastructure as Code (IaC) with AWS CDK

The entire infrastructure, from the S3 bucket to the Lambda functions, is defined using AWS Cloud Development Kit (CDK).
CDK generates CloudFormation templates, ensuring repeatable, version-controlled infrastructure deployments.
This approach simplifies managing resources, allowing for rapid scaling and easy troubleshooting.

6. Scalable and Secure Asset Management

All assets, including images, stylesheets, and scripts, are stored in Amazon S3, ensuring high availability and fast content delivery.
Security configurations include restricted public access to assets and HTTPS encryption for secure data transfer.

Technologies Used

Frontend: React, TypeScript
Backend: AWS Lambda, API Gateway
Database: DynamoDB
CI/CD: CodePipeline, CodeBuild, CodeDeploy
Hosting: S3, CloudFront
Infrastructure: AWS CDK, CloudFormation
Domain Management: Route 53
Security: Secrets Manager

How It Works

User Interaction:
Users interact with the frontend React application hosted on S3 and delivered via CloudFront.
API Requests:
User actions that require dynamic data trigger secure API calls routed through API Gateway to a Lambda function.
Data Handling:
The Lambda function queries the DynamoDB database and retrieves relevant data to serve the user request.
CI/CD Pipelines:
Code updates are automatically built, tested, and deployed using AWS CodePipeline, ensuring the latest version is always live.
Secrets Management:
Sensitive information such as API keys or environment variables is securely retrieved from Secrets Manager during runtime.
