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). Ideal Candidate Profile · *Expertise:* Proven experience in React/TypeScript (specifically with Redux Toolkit and Vite) and deep expertise in AWS Cloud Architecture. · *AWS Certifications:* AWS Certified Solutions Architect or AWS Certified Developer preferred. · *DevOps Skills:* Strong proficiency in Infrastructure as Code (Terraform/CDK), Docker, and CI/CD pipelines. · *Communication:* Ability to explain architectural decisions clearly and provide proactive recommendations for cost-optimization and security.
