Designed, engineered, and deployed SwiftChat, a high-performance, real-time enterprise messaging application utilizing microservices architecture.

• Built a highly responsive frontend using Next.js 16 (App Router), React 19, Redux Toolkit, and Tailwind CSS for smooth real-time UI state synchronization.
• Architected a scalable Node.js/Express.js backend implementing raw WebSockets (ws) and RabbitMQ (amqplib) to handle asynchronous chat queuing and reliable message delivery.
• Integrated Prisma ORM with PostgreSQL (Supabase/Neon DB) for robust data relational schemas, writing highly optimized queries for chat logs and user profiles.
• Containerized both frontend and backend using Docker & Docker Compose, configured Nginx as a reverse proxy, and deployed to DigitalOcean Droplets using automated shell scripts.

Designed and built Mystery Message — an anonymous messaging web app where users receive honest feedback without knowing who sent it, engineered end-to-end from auth to deployment.

• Built a responsive, server-rendered frontend using Next.js 15 (App Router) and TypeScript, with route-based code splitting, protected layouts, and a polished dashboard for managing anonymous messages.
• Implemented a complete authentication flow with NextAuth.js — including credential sign-up, email OTP verification via Resend, and session-aware middleware for route protection.
• Enforced end-to-end type safety using Zod for all API request/response validation, eliminating runtime data errors across client and server.
• Architected a MongoDB (Mongoose) data layer with aggregation pipelines for efficient message fetching, and toggle-based controls to accept or block incoming messages.
• Integrated an AI message suggestion API to generate smart, context-aware prompts for senders, reducing friction and increasing engagement on public profile pages.
• Designed a public-facing /u/[username] route where anyone can anonymously submit messages — zero login required, fully validated, spam-resistant.
