TradeTracer

Construction document processing software that turns large drawing sets and specification manuals into trade-specific PDF packages.

Private Codebase

TradeTracer

Problem

Estimators and contractors must review hundreds of pages to locate and separate the documents relevant to their trade. Inconsistent document formats and tight bid deadlines make that work repetitive and difficult to verify.

Solution

I built a Django application that extracts PDF text, uses OCR when needed, and classifies pages using construction-specific identifiers and rules. Users select their trades, submit documents for background processing, and download organized PDF packages. Page-level classifications, extracted text, and confidence indicators support review.

Outcome

Combines document classification, separation, and verification in one workflow. Teams can prepare trade-specific packages with less manual page sorting while retaining visibility into the processing results.

Stock Analysis Tool

A Python desktop application that applies custom supply-and-demand rules to historical market data and displays the results on interactive charts.

Stock Analysis Tool

Problem

Manually reviewing charts and marking potential supply-and-demand zones is repetitive, especially when comparing stocks across several timeframes.

Solution

I built a desktop application that retrieves historical data through yfinance, applies custom zone-detection logic, and plots potential supply-and-demand areas directly on candlestick charts. Users can search by ticker and switch between intraday and daily intervals.

Outcome

Brings data retrieval, rule-based analysis, and chart visualization into one research workflow. It makes the analysis repeatable and reduces the need to identify and draw every potential zone manually.

Crypto Dashboard

A responsive cryptocurrency research dashboard combining market movers, coin statistics, price history, and related news.

Crypto Dashboard

Problem

Reviewing cryptocurrency performance and related news requires moving between different data sources, making routine research fragmented.

Solution

I built a Django dashboard integrating CoinGecko market data and Mediastack news. Users can explore market movers, search supported coins by name or symbol, and review statistics alongside 30-day price charts. Caching, request timeouts, and availability notices help the application handle external API limits and interruptions.

Outcome

Consolidates market research into a single interface with consistent formatting and clear data-availability feedback. The project demonstrates how separate APIs can support a practical dashboard tailored to an individual workflow.

DJ Helper

A music discovery tool that uses track characteristics to help DJs find candidates for their next transition.

View Code

DJ Helper

Problem

Finding tracks that work together requires comparing tempo, musical key, and energy across a music library—a repetitive part of preparing a DJ set.

Solution

I built a Django application that integrates Spotify data with custom matching logic based on BPM, Camelot key compatibility, and energy. The application presents candidate tracks for further review during set preparation.

Outcome

Turns track characteristics into a focused shortlist of transition candidates. It supports the DJ's selection process by bringing relevant comparisons into one workflow.
