What We Did
Key areas of responsibility, architecture, and technical deliverables engineered for this project.
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.
Secure Payments & Administrator Dashboard

Die Business‑Herausforderung, die wir gelöst haben
Nerihya needed a mobile app and companion SaaS platform built from the ground up in a tight two-month window — covering everything from business onboarding to customer discovery, without an existing product or technical team in place.
Key challenges included:
- Establishing a reliable two-sided marketplace for local trade professionals and homeowners.
- Designing an intuitive promotional tool with digital voucher creation and real-time redemption.
- Ensuring strict 60-day delivery to meet time-to-market commitments without compromising code quality.
