Data Analyst – Financial & Operational Data | Remote

I analyze structured data to support business decisions in financial services, operations, and project management. My work spans SQL-driven analysis, interactive dashboards, statistical validation, and turning complex datasets into actionable insights — with deep domain expertise in financial data and construction cost management.

Selected Data Analysis Projects

Financial Data Analysis Pipeline

Problem: Needed to analyze large financial datasets across multiple time periods while preventing data leakage between analysis windows.

Approach: Built reproducible analysis pipeline with time-aware data splits, cohort segmentation, and automated reporting of key financial metrics.

Outcome: Enabled consistent, auditable analysis across multiple financial instruments with clear documentation of methodology and findings.

SQL Python (pandas) Data Validation Automated Reporting

Market Data Statistical Analysis

Problem: Evaluate whether patterns in forex market data represent genuine trends or random noise.

Approach: Applied statistical testing (bootstrap, permutation tests) across 224K records and 24 instruments. Created summary dashboards showing confidence intervals and significance metrics.

Outcome: Produced rigorous analysis report with clear visualization of findings — including honest reporting that most apparent patterns did not survive statistical scrutiny.

Python Statistical Analysis Data Visualization

Trading Strategy Performance Dashboard

Problem: Traders needed a clear way to evaluate and compare strategy performance metrics.

Approach: Built interactive dashboard calculating expectancy, risk-reward ratios, and drawdown analysis from trade log data (CSV/manual entry).

Outcome: Live tool used for strategy evaluation with exportable PDF reports.

Hebrew Bible Analysis Suite

Problem: No open-source, browser-based platform existed for rigorous computational analysis of Hebrew biblical texts, including replication of the landmark 1994 WRR statistical experiment.

Approach: Built 11-tool analysis platform processing 304,805 letters with Web Workers for off-thread computation, compressed JSON data pipeline (630MB→21MB), and custom visualization including 2D/3D matrix views and Hebrew date heatmaps.

Outcome: Full-featured analysis suite with ELS search, statistical pattern detection, gematria calculator, and the first open-source WRR replication — 100% client-side, zero server dependencies, installable as PWA. Built with Claude Code (Anthropic) as a development accelerator.
