LinkWell — HIPAA-Compliant AI Scribe & Closed-Loop Physician Referral System
Enterprise-grade, HIPAA-compliant closed-loop physician referral and ambient clinical intelligence platform with real-time AthenaHealth EHR integration, automated SOAP note generation, and prior-authorization pipeline.
Client overview
01 / 06Nerihya is a UK-based hyperlocal marketplace platform designed to modernize how homeowners, tenants, and property managers find, hire, and collaborate with skilled local handypersons, tradespeople, and home maintenance contractors.
Rather than relying on outdated static directories or high-fee platforms with opaque booking processes, Nerihya empowers users to discover available service professionals in their immediate neighborhood with sub-second geospatial search, redeem digital promotional vouchers, and chat in real-time to finalize quotes and repair logistics.
Challenge
02 / 06The UK home services sector is historically fragmented. Customers frequently experience unreliable response times, unpredictable pricing, and lack of transparency when hiring independent contractors. At the same time, skilled handypersons struggle to market their services locally without paying prohibitive commissions to large legacy platforms.
Nerihya partnered with Woltrio with an aggressive objective: engineer an intuitive, full-featured two-sided marketplace mobile application and administrative portal from scratch within a strict 2-month MVP timeline, ready for App Store and Google Play deployment.
- •Fragmented local discovery: Homeowners lacked a reliable method to find verified tradespeople within their exact neighborhood radius.
- •Marketplace cold-start: Attracting initial service providers required low-friction onboarding, instant deal creation, and compelling merchant incentives.
- •Aggressive time-to-market: The client needed a complete, production-ready MVP delivered within 2 months without budget overruns.
- •Hyperlocal geospatial search: Needed sub-50ms radius calculations to filter handypersons by distance, rating, and real-time availability.
- •Real-time socket messaging: Required low-latency in-app chat with photo sharing so customers and providers could scope jobs immediately.
- •Integrated voucher & payment security: Seamless digital voucher redemption combined with automated Stripe Connect payouts.
“Woltrio delivered a HIPAA-compliant clinical AI platform that completely changed our practice workflows. The AthenaHealth EHR integration and ambient AI note generation save our clinicians over 90 minutes every day.”

1. Cross-Platform Mobile Application (iOS & Android)
Engineered using React Native and TypeScript, providing native 60fps performance with a single maintainable codebase. Features an intuitive task creation wizard, provider profiles with verified ratings, and one-tap booking flows.

Integrated WebSocket chat infrastructure connects customers and providers instantly for task scoping, photo sharing, customized quotes, and job confirmation without leaving the application.
