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.
Project Lead & Senior Full-Stack Engineer | Atlassian Jira Clone Deployment
Recent
React, Node.js, Express.js, MongoDB Atlas, Mongoose, AWS (EC2, S3), GitHub Actions, PM2, SSL/TLS
Live Production Engine: jira-clone.prasadaraodarla.co.in/login
Designed, developed, and architected an enterprise-grade Atlassian Jira Clone supporting multi-tenant developer sandboxes, dynamic Agile Kanban task workflows, and rigorous administrative user lifecycle management built on a decoupled full-stack architecture.
- Engineered Decoupled CI/CD Pipelines: Designed automated GitHub Actions workflows orchestrating a dual-pipeline strategy that builds and syncs the React frontend directly to an AWS S3 bucket, while concurrently handling automated server tests and hot-deploying the Node.js backend to an AWS EC2 instance using PM2.
- Architected Automated Server Isolation (CORS): Engineered a rigorous dynamic server access policy whitelist array to screen incoming transactions, completely blocking multi-origin vector vulnerabilities while seamlessly supporting both production cloud environments and local development environments.
- Implemented Dual-Layer User Security Governance: Designed a multi-state account lifecycle engine (PENDING, ACTIVE, SUSPENDED) built directly into the Mongoose schema, coupled with a secure backend interceptor middleware stack (
protect, adminOnly) to handle account activation and secure token filtering.
- Developed Workspace Administration Console: Created a corporate governance dashboard allowing real-time administrative approvals, role escalations (standard user to admin), and direct user onboarding while maintaining full backward-compatibility with legacy boolean field tracking (
isBlocked).
- Engineered One-Click Guest Demo Mode: Implemented a pre-seeded, pre-hashed cryptographic guest simulation pathway using custom pre-compiled Bcrypt strings, giving recruiters and visitors instant workspace authorization without bypassing underlying system security filters.
- Secured Automated Base URL Switching Engine: Built an environment-aware API lookup client leveraging Vite’s structural tracking state configurations (
import.meta.env.MODE) to eliminate hardcoded URLs and ensure smooth transitions between local development ports and live cloud servers.
- Deployed Production SSL Environments: Configured secure, live HTTPS native Node server bindings on AWS EC2 backed by certified Let's Encrypt SSL/TLS certificates, establishing secure data transport channels for all frontend client actions.
