PERFORM ARC | Training planning and readiness platform
My own product. Role: Founder and Product Lead.
I lead PERFORM ARC, a training platform for coaches and athletes. Coaches review athlete check-ins, assign training days and compare planned work with completion. The workflow connects readiness signals, coaching decisions and recorded execution in one workspace. A public website presents the product and links to its mobile apps. Readiness indicators support coaching decisions; they are not medical clearance.

Mock Airtable and CSV to a One-Page PDF Report
AI-assisted demonstration using synthetic data, not client work. A local mock Airtable JSON snapshot is joined with an invented CSV schema, then an HTML template is rendered to a one-page PDF. The example validates 2 mock records and 6 CSV rows: 4 selected rows appear in the report and 2 are accounted for separately. Six tests passed, including repeatability and multi-page overflow rejection. Source code, PDF, PNG preview and audit are available. No live Airtable API connection was implemented or tested.

CSV Cleanup with Duplicate and Conflict Reporting
AI-assisted demonstration using synthetic data, not client work. A Python script merges compatible CSV files by an explicit key, removes only exact duplicate occurrences, and sends conflicting or missing-key records to review. The verified example accounts for all 10 input records: 4 clean, 4 for review and 2 duplicates removed. Original files, leading zeros and multiline text are preserved. Six tests passed. Source code, sample outputs, an audit trail and rerun instructions are available.
