📌 Core Engineering & Repositories

  • ⚡ Real-Time API & Event-Driven Backend

    • Built asynchronous REST and WebSocket services using Node.js, Express, and Redis Pub/Sub.
    • Handled auth workflows with JWT/cookies, rate limiting middleware, and structured error handling.
    • Containerized services with Docker for clean local setup and deployment.
  • ⚡ Relational Data Modeling & Caching

    • Designed normalized relational schemas in PostgreSQL with indexed queries and migrations.
    • Implemented Redis cache-aside patterns to reduce database read load on frequent endpoints.
    • Managed database transactions and connection pools to handle concurrent operations cleanly.
  • 🌐 Full-Stack Applications

    • Developed full-stack web applications using Next.js / React, TypeScript, and Tailwind CSS.
    • Built responsive UIs with server-side rendering, client state management, and end-to-end type safety.
    • Connected frontends to REST APIs with validation and optimistic UI updates.
  • 🧩 Algorithms & Core Systems

    • Implemented core data structures, caching policies (LRU), and algorithm solutions in Java, C++, and TypeScript.
    • Explored concurrency models, event loops, and asynchronous patterns across different runtimes.
