Live Production Engine: intelligent-rag.prasadaraodarla.co.in
Reference Architecture Validation Data: rag-test-sample.txt.pdf
Designed and engineered a production-ready, highly secure Intelligent Retrieval-Augmented Generation (RAG) platform capable of context-aware document processing and deterministic query rate limiting.
- AI & Orchestration Frameworks: Built the orchestrator layer using LangChain and Google Gen AI models to manage smart prompt templates, track conversational history contexts, and handle deterministic system data parsing pipelines.
- Data Ingestion & Verification: Implemented automated parsing, chunking, and vector embedding pipelines optimized for context retrieval, utilizing the hosted reference validation data to run end-to-end system verification, validate response accuracy, and eliminate LLM hallucinations.
- Frontend & Static Hosting: Developed a modular, high-performance Angular frontend optimizing client-side state management. Leveraged Amazon S3 for decoupled static web hosting and AWS CloudFront for global content caching, edge routing, and root-object routing (
index.html).
- Backend Architecture & Security: Architected a scalable Node.js/Express backend deployed within a containerized multi-service cloud environment. Engineered custom middleware handlers (
response.js, query_route.js) to strictly manage core responses and enforce aggressive, production-grade IP rate limits capped at 10 queries per window.
- Containerization & DevOps: Orchestrated the entire infrastructure lifecycle using Docker and Docker Compose, building completely isolated container layers to facilitate zero-downtime microservice restarts, unified log management, and clean environment variable injection.

Live Production Engine: zoom-clone.prasadaraodarla.co.in
Architected an end-to-end cloud-native video conferencing topology leveraging a decoupled single-page application structure and WebRTC protocols to handle low-latency peer-to-peer media streams.
- System Design & Cloud Architecture: Leveraged AWS S3 for secure static React SPA asset hosting paired with an AWS CloudFront Distribution over HTTPS to achieve low-latency global delivery and eliminate edge-connection overhead.
- API Gateway & Proxy Integration: Designed a custom CloudFront routing behavior matrix, structuring strict path boundaries to proxy core REST API endpoints (
/api/*) and WebSocket channels (/socket.io/*) directly to an independent Node.js cluster on AWS EC2 managed via PM2.
- Real-Time Signaling Mesh: Engineered a hybrid real-time signaling engine combining Socket.io orchestration with a backend-integrated
ExpressPeerServer instance to handle multi-user handshakes (SDP Offers, Answers, and ICE Candidates) for cross-device media tracking.
- Data Modeling & Security Gates: Enforced cryptographic regex match patterns for 9-digit numeric virtual room boundaries within Mongoose schemas, building a secure token-verification entry gate (
/verify-gate) to validate room and pin presence before initializing hardware allocations.
- Concurrency & Lifecycle Optimization: Resolved production infrastructure anomalies, including asynchronous environment variable hydration race conditions within ES Modules, strict data-type casting failures (
CastError), and engineered graceful multi-peer teardowns to preserve server stability during abrupt network drops.

Live Production Engine: tasks.prasadaraodarla.co.in
Architected and delivered a decoupled, production-live Task Manager application utilizing a split-subdomain infrastructure (tasks and tasks-api) to strictly isolate client-side assets from backend API traffic.
- Robust Backend Engineering: Developed secure RESTful endpoints with Spring Boot and MySQL, implementing efficient data persistence via Spring Data JPA and structural cross-domain protection through tailored CORS policies.
- Modern SPA Architecture: Designed a modern Single Page Application using React and Vite, utilizing Axios for optimized async API consumption and managing clean state transitions for dynamic task lifecycles.
- Global Content Delivery: Deployed a serverless frontend infrastructure leveraging Amazon S3 and CloudFront for global content caching, configuring custom error-handling overrides to ensure seamless client-side routing on refreshes.
- Hardened Cloud Infrastructure: Provisioned and hardened AWS EC2 and RDS (MySQL) environments, establishing isolated VPC security groups to restrict direct database accessibility solely to the backend compute layer[cite: 1].
- Automated CI/CD Workflows: Orchestrated independent CI/CD pipelines using GitHub Actions across separate repositories, enabling zero-downtime, automated deployments triggered instantly upon code pushes to the prod branch[cite: 1].
- Reverse Proxy & DNS Configuration: Configured multi-subdomain routing via Nginx on Ubuntu, securing end-to-end web traffic transit using GoDaddy delegated nameservers and an enterprise Wildcard SSL certificate[cite: 1].

Live Production Engine: weather-lens.prasadaraodarla.co.in
A lightweight, lightning-fast, offline-first weather tracking application built completely from scratch using native web standards to achieve maximum performance and zero ongoing server maintenance overhead.
- Native Frontend Architecture: Engineered the entire user interface and application layer using pure HTML5, CSS3 (Grid/Flexbox), and Vanilla JavaScript, ensuring an incredibly small bundle size, zero framework overhead, and instant DOM rendering.
- Serverless Hosting & Global Delivery: Architected a highly secure, cost-effective infrastructure on AWS by deploying production assets to a private Amazon S3 bucket. Configured Amazon CloudFront as a global CDN using Origin Access Control (OAC) to keep the S3 origin fully isolated from the public internet.
- Custom DNS & Managed SSL: Configured advanced routing via AWS Route 53 to handle custom subdomains, integrated with free, auto-renewing SSL certificates provisioned via AWS Certificate Manager (ACM) to enforce strict HTTPS transport channels.
- Advanced PWA Caching Lifecycle: Authored a robust native Service Worker implementing an advanced multi-tier caching architecture to guarantee comprehensive offline functionality: Cache-First for core App Shell assets, Network-First with automatic offline JSON state fallbacks for external REST weather/geocoding APIs, and Stale-While-Revalidate for Google Fonts.
- Automated Cache-Busting Pipeline: Resolved complex mobile container lifecycle challenges where devices hold onto stale assets by implementing an automated upgrade pipeline using custom S3 Cache-Control metadata headers, service worker version increments, and a native DOM
controllerchange event listener to force clean, background refreshes on live client viewports upon new code deployments.
