TheMarketBug
A comprehensive financial data platform built from the ground up. Features proprietary charting technology, real-time market data pipelines, congressional trading data tracking, SEC filing analysis, and other public financial data integrations — all delivered through a custom-built front end.
The Challenge
Why This Was Hard
Financial data is messy. Multiple APIs return different formats, different timestamps, different precision. Existing charting libraries couldn't render real-time candlestick data at the speed and granularity required — they'd choke on the update frequency or produce visual artifacts during rapid redraws. On top of that, congressional trading data comes from scattered government filings that need to be parsed, normalized, and cross-referenced with live market data to be useful.
The Solution
What I Built
Built a custom charting engine from scratch using Canvas API for sub-second candlestick rendering with zero visual artifacts. Designed a normalization pipeline that ingests disparate financial data sources and unifies them into a single format with consistent timestamps and precision. Congressional trading and SEC filing data flows through a dedicated parser that cross-references holdings with real-time price data automatically.
