Market Maven — Stock Data Analysis System
A modular Python pipeline for ingesting, processing, and reporting on stock market data.
What it does
Market Maven pulls market data, runs it through a processing pipeline, and generates reports — built around the Observer pattern so that ingestion, processing, and report generation stay decoupled. Each stage listens for events from the one before it rather than being called directly, which made it possible to test each module in isolation.
Engineering details
- Dedicated classes for data ingestion, processing, and report generation, connected through an Observer-based event flow
- Reduced processing errors from 12% to under 2% through systematic edge-case testing and input validation
- Full codebase managed on GitHub with structured branching and inline documentation across the SDLC, from requirements through delivery
