Overview

Slash is a productivity-focused Chrome extension that helps users type faster by expanding short commands (like /email, /sig, or /addr) into full text instantly — anywhere on the web.

Instead of repeatedly copying, pasting, or retyping the same information, users define shortcuts once and reuse them seamlessly across emails, forms, chats, dashboards, and documents.

The extension is designed to be minimal, fast, privacy-first, and secure, with a backend-driven architecture to support future scaling and advanced features.

Features

  • Instant text expansion using /shortcuts
  • Works on all websites where users type
  • Secure Google login for syncing shortcuts
  • SMTP automations (SendGrid / AWS SES) for the internal team
  • Prop firm evaluation logic with clear challenge progression
  • Affiliate partner system with tracking + commission dashboards
  • User activity, logs & audit trails for compliance

Technical Stuff

Backend

Slash is built as a Chrome Extension (Manifest V3) using modern tooling:

  • Plasmo for clean extension structure and DX

  • React + TypeScript for popup UI and logic

  • Service Worker–based background scripts for handling auth, sync, and messaging

  • **chrome.storage.local for secure local persistence

  • Firebase Auth is used for Continue with Google login UI

Backend

The backend is engineered for real-time capabilities, secure high scalability:

  • Node.js + Express.js used for CRUD Operations and REST APIs.

  • MongoDB for storing user shortcuts and metadata

  • JWT-based two tier authentication with refresh token rotation

Admin Dashboard Features

Built a comprehensive admin panel with:

  • Analytics dashboard with key metrics
  • Content management system for website data
  • Role based permission handling team of 15+ Members
  • Performance monitoring tools

Technical Challenges & Solutions

Challenge 1: High Traffic from Influencers

  • Problem: Surges in traffic after influencer posts (10K visitors in first launch hour)
  • Solution: Auto-scaling AWS infrastructure.

Challenge 2: Database Scaling & Query Performance

  • Problem: Increased load from analytics, dashboards, and admin tools led to slow queries and lock contention.
  • Solution: Applied proper indexing strategies, query optimization, and read/write separation. Introduced Redis caching for frequent queries and background jobs for heavy data aggregation.

Challenge 3: Real-time Synchronization

  • Problem: Ensuring critical emails (payments, account updates, alerts) were delivered reliably during peak traffic.
  • Solution: Built a queued email system with retry logic, fallback SMTP providers, delivery tracking, and alerting on failure rates to maintain high deliverability.

Performance Optimizations

  • Implemented lazy loading for better initial load times
  • Used proper caching strategies for static assets
  • Efficient DB indexing + query tuning for faster response times
  • Added rate limiting to prevent API abuse
