## 2. Engineering Case Studies

### Case Study A: Universal IDE RTL Support
- **Problem Statement:** Modern AI code editors (Cursor, Windsurf, Claude Code, Antigravity, VS Code) render right-to-left (RTL) scripts (Hebrew, Arabic, Persian) incorrectly inside chat panels. Text punctuation flips, English technical terms inside Hebrew sentences become scrambled, and basic readability degrades.
- **Engineering Solution:**
  - Designed an open-source extension utilizing dynamic DOM mutation observation and targeted CSS/JS style injection into the IDE's Electron window.
  - Formulated regex-based BiDi boundary isolators that apply RTL styles specifically to natural language text without mutating inline code spans (`<code>`), markdown syntax blocks, or shell commands.
  - Handled sandboxed iframe permissions in VS Code Webview architecture.
- **Results:**
  - 6,700+ active downloads on the Open VSX registry.
  - 5.0 / 5.0 star user rating.
  - Zero performance degradation on editor frames per second (FPS).

  - Marketplace Listing: https://open-vsx.org/extension/talco/universal-ide-rtl

### Case Study B: Real-Time Rental Apartment Hunter (Yad2 Bot)
- **Problem Statement:** The rental apartment market in Tel Aviv requires instantaneous notifications upon listing publication. Manual searching is highly inefficient.
- **Engineering Solution:**
  - Engineered an automated Python-based scraping and polling engine designed to bypass aggressive rate limiting and bot detection.
  - Stored historical listings in MongoDB to eliminate duplicate alerts and track price trajectory over time.
  - Integrated Telegram Bot Webhooks for sub-3-second notification delivery to mobile devices.

### Case Study C: Collaborative Coding Environment
- **Problem Statement:** Remote pair programming and mentoring requires low-latency shared editor state across different network conditions.
- **Engineering Solution:**
  - Built a full-stack platform using React, TypeScript, Node.js, and WebSockets.
  - Synchronized editor state in real-time with responsive UI design.
