Cattle health records still live in paper notebooks across LATAM farms. Cattle Verify digitizes RFID field encounters, QR packaging traceability, and immutable compliance exports in a Capacitor PWA with 90%+ offline usage.
Dec 2025 - May 2026
Distribution-led traceability for animal health sponsors at Wamo. White-label admin lets sponsors manage product catalogs and QR codes. Field teams capture vaccinations, medications, and lab samples via BLE RFID scanners through a Capacitor native shell. An append-only clinical ledger in DynamoDB feeds PDF/CSV export packets for Argentina and LATAM regulatory pilots across 45 screens and 77 API endpoints.
Full-stack engineer on collection PWA and admin portal for encounter capture, sync, and compliance export pipelines.
RFID encounter workflows, QR code generation linking packaging to animal records, program-driven validation rules, nine-role RBAC hierarchy, and immutable PDF/CSV export packets for regulatory audits.
PE firms lose billable hours to manual timesheet entry and scattered calendar data. BillPilot syncs Google and Microsoft calendars, runs approval workflows, and generates rate-based invoices from a multi-tenant AWS SAM backend.
DRC miners often wait weeks for fair payment with no proof of ore quality. PowerLink Mining is an offline-first PWA with AI ore verification, M-Pesa and Airtel payouts, and Celo chain-of-custody on AWS SAM in af-south-1.
User-reported bugs often lack reproducible evidence for engineering teams. Verity runs Playwright in AWS Lambda to capture screenshots, JS errors, and API failures, then deduplicates and scores issues before GitHub triage.
