NexaData AI Data Quality Platform
Real-time data quality, validation, and error detection
Role: Founder & Data Systems Engineer
Stack
Founded and engineered NexaData as a web-based data quality platform that helps teams upload CSV, Excel, JSON, or XML datasets and immediately understand their reliability. The platform combines quality scoring, AI-assisted summaries, automated issue detection, suggested fixes, rule discovery, and report-ready views in one workflow.
Impact
Built a product workflow that moves users from dataset upload to quality score, visible issues, error table, auto-detected rules, rule builder, unique-value checks, AI summary, and actionable improvement recommendations.

Measured indicators
Dataset intake
Supports structured upload and analysis flows for CSV, Excel, JSON, and XML files, with dataset context shown before the user starts validation.
Quality scoring
Calculates an overall dataset health score with visible issue counts, issue rate, column risk, and improvement signals that make quality status easy to interpret.
Error table
Shows row-level and column-level problems such as missing values, format mismatch, duplicate rows, corrupted values, and coordinate issues, with suggested fixes and confidence states.
Auto-detected rules
Detects candidate validation rules from the dataset, compares wrong and current values, proposes normalized fixes, and lets users add, edit, or remove rules.
Rule builder
Gives users a controlled way to define custom validation and uniqueness checks, turning recurring data problems into reusable quality rules.
AI summary
Produces human-readable explanations of dataset health, main issue patterns, and the top improvement opportunity for better reporting consistency.
