## Summary

John Marwin Ebona turns messy data and business problems into decisions people can defend. He has built an audit-ready analytics platform, a risk engine screening 50,000+ wallets, and an ERP used daily by a live business. He has led teams, six-country market research and a five-year financial model across 12 hackathons and ideathons.

## Startup

- VIS/CODE (https://viscodeai.netlify.app/) — founded and built by John Marwin Ebona. "Read any codebase in ninety seconds." It turns a codebase in 40+ languages into a clickable map (architecture, file and flow levels) inside the browser, with an AI assistant that only answers from the part of the map in view and cites the exact lines. No code is uploaded or executed. Target customers: engineering teams onboarding hires, agencies handing over client projects, investors running technical due diligence, and educators. Proposed revenue model: free for public repositories; paid seats for private repositories and team workspaces; per-report pricing for due-diligence exports.

## Projects

- Evidentia (https://evidentia-ph.netlify.app/) — data-to-decision analytics platform. Sole designer, developer and analyst. Validates 20,875 records in one pass with 40+ data-quality checks and a weighted Data Health Score; reconciliation, variance, forecasting and scenario analysis; named sign-off, hash-chained audit trail, and an AI guard (Amazon Bedrock) that rejects untraceable figures; 214 automated tests.
- Sentinel Ledger — real-time stablecoin payout risk engine (https://github.com/qjmre23/Real-Time-Stablecoin-Payout-Risk-Scoring-System). Scores 50,000+ wallets across 54 tokens and returns ALLOW, REVIEW or BLOCK with probability, confidence and a plain-language reason. Versioned Random Forest, XGBoost and LightGBM models with leakage-safe validation and rollback; 100% held-out recall on address-poisoning attacks; NetworkX graph signals.
