Senior React/TypeScript Developer & AWS Cloud Architect

*Project Overview* We are looking for an experienced Full-Stack/Cloud Developer to build a public-facing marketplace website and architect the underlying AWS infrastructure. We have already developed the backend (a private Spring Boot API) and a client admin console (Spring Boot Thymeleaf). This is a phased project. *Phase 1 (Immediate):* Develop the public website and set up the AWS Dev environment for it. *Phase 2 (Future):* Expand the AWS infrastructure to Staging and Production environments to host the website, the Spring Boot API, the Admin Console, and the PostgreSQL database. Please review the detailed requirements below. *Section 1: Website Development (Public-Facing Marketplace)* *Objective:* Develop a highly responsive, performant, and type-safe public website that consumes my existing Spring Boot API exclusively. The site will feature business listings, interactive maps, advanced filtering, and user submission flows. *Required Technology Stack:*

• *Core Framework:* React.js with TypeScript (Component-based architecture for reusable UI elements like listings, maps, and filters).
• *State Management:* Redux Toolkit + RTK Query (Centralized store for search filters, auth, and listing data; RTK Query for efficient API caching/loading states and geospatial state management).
• *Styling:* Tailwind CSS + Headless UI (Utility-first CSS for rapid responsive design, marketplace UI patterns, and customizable map controls).
• *Build Tool:* Vite (For lightning-fast HMR, native ES module bundling, and fast initial loads).
• *Mapping Integration:* Google Maps Platform + @react-google-maps/api (For drawing search radius circles, click-to-place listing submissions, and geolocation-based initial map positioning).
• *Form Management:* React Hook Form + Zod (Performant form handling for business submissions, Zod for schema validation like business hours/coordinates, integrated with Dropzone for image uploads).
• *API Communication:* Axios + OpenAPI Generator (Type-safe API calls to the Spring Boot backend. You will generate API types directly from my OpenAPI spec via Springdoc. Must include automatic retry logic for geospatial queries).
• *Testing Stack:*
• _Unit Tests:_ Vitest (Component logic, custom hooks).
• _Integration Tests:_ React Testing Library (Listing filters, map interactions).
• _E2E Tests:_ Cypress (User journey from search to listing submission).

*Deliverables for Section 1:*

• Fully functional, responsive React/TypeScript frontend application.
• Comprehensive test suites (Unit, Integration, E2E) with high coverage.
• Clean, well-documented source code adhering to modern React best practices.

*Section 2: AWS (Dev) Setup for Website* *Objective:* Design and implement the initial AWS Dev environment specifically tailored for hosting, testing, and continuous deployment of the React website. *Requirements:*

• *Hosting & CDN:* Set up Amazon S3 for static website hosting and Amazon CloudFront for global content delivery and caching.
• *DNS & SSL:* Configure Amazon Route 53 for DNS management and AWS Certificate Manager (ACM) for SSL/TLS certificates (HTTPS).
• *CI/CD Pipeline:* Implement an automated CI/CD pipeline (e.g., GitHub Actions, GitLab CI, or AWS CodePipeline) that triggers on git pushes to:

1. Run linting and tests (Vitest/Cypress). 2. Build the Vite production bundle. 3. Deploy the artifacts to the S3 bucket and invalidate the CloudFront cache.

• *Infrastructure as Code (IaC):* All Dev infrastructure must be provisioned using IaC (Terraform or AWS CDK preferred) to ensure reproducibility.
• *Security:* Implement least-privilege IAM roles for the CI/CD deployment user and secure the S3 bucket via Origin Access Control (OAC).

*Deliverables for Section 2:*

• Fully deployed and accessible Dev environment URL for the website.
• Working CI/CD pipeline configuration files.
• IaC codebase for the Dev environment.
• Brief documentation on how to manage the Dev environment and pipeline.

*Section 3: AWS (Staging/Prod) Setup for Website and 2 Spring Boot Applications* *Objective:* Architect and deploy the complete Staging and Production environments. This phase expands the infrastructure to host the entire ecosystem: the React Website, the Spring Boot API, the Spring Boot Thymeleaf Admin Console, and the PostgreSQL database. _(Note: The Spring Boot apps are already developed; this phase is strictly for infrastructure, deployment, and O&M setup)._ *Requirements:*

• *Networking & Security:*
• Design a secure VPC architecture with Public and Private subnets across multiple Availability Zones.
• Configure NAT Gateways, Security Groups, and Network ACLs.
• Implement AWS WAF (Web Application Firewall) for the public-facing endpoints.
• *Database (PostgreSQL):*
• Provision Amazon RDS for PostgreSQL.
• Configure automated backups, Multi-AZ deployment (for Prod), and parameter groups.
• Store DB credentials securely in AWS Secrets Manager.
• *Compute & Application Hosting:*
• Host the Spring Boot API and Admin Console using a managed container service (Amazon ECS Fargate).
• Set up Amazon Elastic Container Registry (ECR) to store Docker images for both Spring Boot applications.
• Configure Application Load Balancers (ALB) to route traffic to the appropriate backend services and handle SSL termination.
• *Monitoring & O&M:*
• Configure Amazon CloudWatch for centralized logging, metrics, and alarms.
• Set up automated scaling policies (Auto Scaling) based on CPU/Memory or request count.
• Implement AWS X-Ray or similar for distributed tracing between the frontend, API, and database.
• *Infrastructure as Code (IaC):*
• Expand the existing IaC codebase to manage Staging and Prod environments, utilizing workspaces or separate state files to prevent cross-environment contamination.

*Deliverables for Section 3:*

• Fully operational Staging and Prod environments for all 3 applications and the database.
• Complete, modular IaC codebase covering the entire AWS architecture.
• Comprehensive architecture diagrams and an Operations & Maintenance (O&M) runbook (including backup/restore procedures, scaling instructions, and monitoring alerts).
