Prompt Like A Pro — AI Meta-Prompting Workbench

Prompt Like A Pro is a meta-prompt engineering platform powered by React 18, Vite 5, and serverless edge architecture. It features an automated multi-provider key rotation pool aggregating free-tier quotas across Google Gemini, Groq, OpenRouter, and Hugging Face with dual-environment support (custom Vite dev proxy locally and Vercel Serverless Functions in production). The platform includes a token-efficiency engine reducing consumption by 60%–70%, a zero-dependency offline heuristic engine for fallback resilience, dynamic placeholder parsing, and persistent localStorage state management.

AlgoFlowX — Interactive DSA & Algorithm Visualizer

AlgoFlowX is a high-performance Data Structures & Algorithms visualizer built with React 19, Vite, and Framer Motion. It features a custom step generator engine powering 19 comprehensive DSA modules across sorting, searching, linked data structures, trees, and graphs. The system incorporates synchronized line-by-line code tracking across 5 programming languages (Python, C, C++, Java, JS), a real-time memory and pointer HUD, a head-to-head Algorithm Duel Arena with live microsecond and swap metrics, and a native Web Audio API sonification engine mapping frequency tones (220 Hz–1320 Hz) to runtime memory operations.

UniVibe — University Social Media Platfrom

UniVibe is an enterprise-readyapplication architecture engineered for rapid development cycles and robust scalability. Built on React 18, TypeScript, and Vite, it delivers instant Hot Module Replacement (HMR) alongside pluggable compiler toolchains via @vitejs/plugin-react (Oxc) and @vitejs/plugin-react-swc. The system features a production-grade ESLint and TypeScript AST configuration enforcing type-aware linting, strict code quality guards, and an extensible component-route directory structure optimized for medium-to-large scalable web applications.

NeuroStack — Personal AI Knowledge Hub

NeuroStack is an automated personal knowledge repository featuring a high-performance React 18 + Vite PWA frontend and a serverless backend powered by Firebase Firestore and GitHub Actions cron jobs (running daily at 06:00 UTC). It ingests public RSS and YouTube feeds without requiring third-party API keys, processes articles and transcripts using Google Gemini 1.5 Flash for structured Markdown summaries, and syncs data to Firestore. The client incorporates an IndexedDB-backed smart cache to minimize read quotas and enable offline access, backed by Firebase Auth and granular Firestore rules for the admin dashboard.
