CryptoPulse – Real-Time Financial Transaction Pipeline
This project establishes a high-performance, serverless streaming architecture designed to ingest and analyze live cryptocurrency market data. By utilizing a reactive AWS stack, the pipeline processes thousands of trade events per second with sub-second latency, providing immediate insights into market sentiment and volume distribution.
The Architecture
Live Ingestion: A custom Python Producer maintains a persistent connection to the Coinbase WebSocket API. It captures raw trade events for BTC, ETH, and SOL, performing real-time data enrichment (calculating USD trade value) and rigorous validation before streaming.
Streaming & Buffering: AWS Kinesis Data Streams acts as the high-throughput backbone, decoupling the data producer from consumers and ensuring the system can scale to handle sudden market volatility.
Serverless Processing: An AWS Lambda function is auto-triggered in optimized batches (100 records or 5-second windows). It handles base64 decoding, deduplicates trades via trade_id to ensure exact-once processing, and executes bulk inserts into storage.
Fault Tolerance: To ensure zero data loss, a Dead Letter Queue (AWS SQS) automatically captures any failed records, allowing for isolated troubleshooting and reprocessing without stalling the main pipeline.
Storage & Visualization: Data is persisted in Amazon Redshift for analytical depth. A Streamlit Dashboard queries these tables to visualize live buy/sell ratios, trade size distributions, and 1-minute moving aggregations.
Key Technical Strengths
Event-Driven Scaling: The serverless design ensures costs only scale with actual trade volume.
Data Integrity: Multi-stage validation and SQS-based error handling guarantee high-quality data for financial analysis.
Low-Latency Insights: The path from trade execution on Coinbase to visualization on the dashboard is completed in near real-time.
