Client overview

01 / 06

Nerihya is an innovative UK-based hyperlocal services marketplace designed to connect homeowners, tenants, and property managers with verified local handypersons, tradespeople, and home maintenance professionals.

Rather than relying on outdated static directories or high-fee platforms with opaque booking processes, Nerihya empowers users to discover available service professionals in their immediate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, clip and redeem digital promotional vouchers, and chat in real-time to finalize quotes and repair logistics.

End-to-End Product Discovery & UI/UX Design
Mapped user personas, crafted user journeys, and delivered production Figma wireframes for both customer and handyperson interfaces.
Cross-Platform Mobile App Development
Engineered performant iOS and Android apps featuring location-based discovery, real-time push alerts, and streamlined booking.
Digital Voucher & Offer Engine
Built dynamic coupon and promotional voucher features allowing vendors to run targeted marketing campaigns to nearby customers.

Challenge

02 / 06

The 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.

Aggressive 2-Month Delivery Timeline

Adopted a reusable design system and dual-track agile sprint cycles with continuous integration.

→ Delivered complete MVP on schedule within the agreed budget.
Hyperlocal Proximity Matching

Optimized spatial indexing and location filtering in PostgreSQL for sub-second query performance.

→ Instant search results with smooth map-based browsing.
“What impressed me most was Woltrio's commitment to understanding the vision behind Nerihya rather than simply building what was specified. They took a collaborative approach, offering thoughtful suggestions to improve the product, communicating proactively throughout development, and maintaining a high standard of technical quality.”
