Modules

CloudFront DistributionCDN

Global edge network serving the resume site. Optimizes asset delivery speed and provides SSL/TLS encryption for the frontend.

S3 FrontendStatic Hosting

Secure bucket storing the compiled Next.js assets. Acts as the origin for CloudFront, housing the glassmorphism UI/UX components.

API GatewayIngress

Manages incoming RESTful traffic. Routes frontend requests to the business logic layer while handling throttling and basic auth.

Lambda Business LogicAPI/Backend

Core processing hub using FastAPI. Handles asynchronous I/O, injects "Phong Digital Twin" persona into system prompts, enforces real-time guardrails (keyword/semantic filtering), and orchestrates session data between memory and the Neural Engine.

S3 Memory StoragePersist Layer

Encapsulated storage for conversation history, user metadata, and system configuration files (MESSAGES, CONFIG, SESSIONS).

Neural Engine (OpenAI)LLM Processor

External AI intelligence module. Processes the processed prompts and returns context-aware persona responses from Phong Digital Twin.

Terraform IaCOrchestration

Infrastructure as Code layer. Defines and manages consistent deployment of all AWS resources, networking, and security policies.

This diagram and component breakdown illustrate the cloud-native architecture of my Resume platform. It features a Next.js frontend deployed on AWS S3/CloudFront and a FastAPI backend running on AWS Lambda via API Gateway, orchestrated by Terraform.
