Portfolio
Hands-on projects built to demonstrate real-world architecture patterns.
Each project is fully working code — not mockups — designed to showcase
production-grade thinking across distributed systems, event-driven design, and AWS.
Projects
ShopFlow
Event-Driven Microservices
A fully working order processing system built with Node.js and AWS (SNS, SQS, DynamoDB).
Demonstrates pub/sub fan-out, dead letter queues, atomic stock reservation,
event sourcing, and distributed tracing — all patterns used at scale by companies like Uber and Amazon.

RAG Knowledge Assistant
AI / LLM Engineering
A Retrieval-Augmented Generation (RAG) system that lets you chat with your own documents.
Upload PDFs or knowledge-base articles, ask questions in plain English, and get accurate answers
grounded in your data — not hallucinations. Built with LangChain, ChromaDB, and a local LLM.
🚧 Coming Soon
Real-Time Analytics Dashboard
WebSocket · React · Node.js
A live metrics dashboard that streams real-time data from a Node.js backend to a React frontend
using WebSockets. Demonstrates high-frequency data ingestion, time-series aggregation,
and efficient UI rendering patterns — commonly asked in senior frontend and full-stack interviews.
🚧 Coming Soon
EDA Patterns Demonstrated
Pub / Sub
SNS fan-out delivers one event to all subscribers simultaneously
Message Queue
SQS decouples producers from consumers — services run independently
Dead Letter Queue
Failed messages are captured after 3 retries — nothing is silently lost
Event Sourcing
Immutable audit log records every event — full order history preserved
Atomic Operations
DynamoDB conditional writes prevent overselling under concurrent load
Correlation IDs
orderId threads through every event enabling end-to-end tracing
