## Projects

### Cooldesk — Smart new-tab browser extension and desktop app
- Status: Building · 2025 · Browser Extension and Desktop App
- Live: https://cool-desk.com
- Tech: React, Chrome APIs, Vite, OpenAI, Web Speech API, IndexedDB, Rust, Tauri, Desktop

A workspace OS for the browser. Each workspace is isolated with its own pinned tabs, notes, shortcuts, and context. An AI layer learns what you were working on and surfaces relevant tabs, docs, and reminders; voice actions let you control it hands-free. Hardest problem: Chrome's service worker lifecycle kills background workers after 30 seconds, so reliable workspace persistence required a hybrid of chrome.storage, IndexedDB, and a keep-alive heartbeat strategy.

### ReelRanker — AI tier lists from Instagram reel comments
- Status: Building · 2025 · Browser Extension
- Code: https://github.com/abhayraghuwanshi/cool-comments
- Live: https://chromewebstore.google.com/detail/lgmmijdpaemlkihjmelodijggablcgdf
- Tech: TypeScript, React, Tailwind CSS, Vite, Chrome Extensions MV3, Google Gemini API, OpenAI TTS, WebCodecs, Canvas API, dnd-kit, IndexedDB

Chrome extension that scrapes up to 60 Instagram reel comments (including GIFs), ranks them into S–F tiers using Google Gemini with three personality modes (Default, Savage, Indian), and renders an interactive drag-and-drop tier board. Generates AI voiceover scripts via OpenAI TTS and exports 1080×1920 reel videos plus chroma-key overlay clips at 30fps. Hardest problem: animated GIFs freeze in off-screen canvas contexts — fixed with WebCodecs ImageDecoder for frame-by-frame decoding with per-frame bitmap caching.

### Hinge Genie — AI-powered dating swiping assistant
- Status: Archived · 2025 · AI Tool
- Code: https://github.com/abhayraghuwanshi/hinge-genie
- Tech: React, FastAPI, Python, Claude API, Vision Models, Chrome Extension

Generates context-aware, natural conversation replies for dating apps by reading the full profile (photos, prompts, answers). Calibrates tone per user so replies stay in your voice. Key insight: early versions sounded AI-generated because they were too polished — a "naturalness pass" deliberately introduces small imperfections (shorter sentences, contractions, casual phrasing) to match how people actually text.

### InfraPlan — AI cloud architecture planner
- Status: Paused · 2025 · AI Tool
- Live: https://infraplan.cloud/
- Tech: React, FastAPI, LLM, AWS Pricing API, Terraform, D3.js

Describe what you want to build — InfraPlan generates a cloud architecture, monthly cost breakdown per service, and a phased scaling strategy before you write infra code. Also flags common mistakes (e.g., single-AZ RDS for 50k DAU). Built a caching layer over the AWS Pricing API to get reliable estimates without hammering rate limits.

### K8s Diagram — Visual Kubernetes YAML generator
- Status: Active (Live) · 2024 · Developer Tool
- Code: https://github.com/abhayraghuwanshi/k8singress
- Live: https://k8sdiagram.fun/
- Tech: React, TypeScript, ReactFlow, Vite, Tailwind CSS, shadcn/ui, Kubernetes

Drag-and-drop diagram builder that generates production-ready Kubernetes YAML. Supports Ingress (TLS, path rules), Services, Deployments with sidecar/init containers, ConfigMaps, Secrets, PVCs, CronJobs, HPAs, and standalone Pods, with cloud provider annotation templates for AWS/GCP/Azure. YAML import auto-reconstructs the visual graph with correct connections, and a GitHub-backed community template library supports contribution via a built-in PR flow.

### 3D Portfolio — Interactive system-simulator style portfolio
- Status: Paused · 2025 · Creative / Frontend
- Code: https://github.com/abhayraghuwanshi/3dfolio
- Tech: Three.js, React, WebGL, D3.js, GLSL

A portfolio where projects are live service nodes in a system graph — health indicators, dependency edges, logs, and a quest layer that unlocks deeper access through small challenges. Implemented a LOD system and debounced physics for off-screen nodes to keep WebGL performance acceptable on lower-end devices.

### YouTube Streaming Overlay — Stream overlay with a local AI companion
- Status: Building · 2024 · Streaming Tool
- Code: https://github.com/abhayraghuwanshi/cool-stream-overlay
- Tech: React, Ollama, Llama 3.2, WebSocket, OBS Browser Source

OBS browser-source overlay with an AI companion that runs fully on-device via Ollama. It reads chat, reacts to stream moments, answers viewer questions, and can whisper private info to the streamer. Streaming token output makes responses appear word-by-word to mask local-model latency.

### Dropquest — C2C delivery marketplace powered by travelers
- Status: Archived · 2024 · Full Stack
- Code: https://github.com/abhayraghuwanshi
- Tech: React.js, Spring Boot, PostgreSQL, PostGIS, Redis, WebSocket, OAuth2, JWT

Marketplace connecting parcel senders with travelers who have spare luggage space, with three user roles and route-based matching. Real-time delivery tracking via WebSocket; OAuth2 + JWT auth. Route matching was O(n²) with naive geo queries — solved with PostGIS and bounding-box pre-filtering before the full route overlap check.

### AI Movie Script Generator — Collaborative AI-powered scriptwriting platform
- Status: Archived · 2024 · AI Tool
- Code: https://github.com/abhayraghuwanshi
- Tech: React, FastAPI, Python, WebSocket, Material-UI, AI Agents, LangChain

Real-time collaborative screenwriting where AI agents play specific characters — each with a defined personality, speech pattern, and story knowledge — to generate dialogue or improvise scenes together. Visual timeline editor with story branching and voice meeting integration. Character voice consistency over long scripts solved with per-character personality embeddings plus a rolling summary injected into every generation request.
