TrustFix

Inspiration

In many developing urban markets across Africa, finding a reliable electrician, plumber, or mechanic relies heavily on word-of-mouth recommendations. Homeowners risk low-quality service or fraud, while skilled independent artisans lack a digital presence to build a reputation. We built TrustFix to bridge this trust gap by creating a transparent, AI-enhanced service marketplace tailored for emerging regions.

What it does

TrustFix connects local homeowners directly with verified service professionals.

• AI Smart Search & Matching: Powered by Google Gemini AI to analyze user repair requests and match them with relevant artisans based on domain expertise and community track records.
• Automated Credibility Verification: Evaluates artisan profiles, skills, and client reviews to maintain high community trust standards.
• Edge Performance: Built to load ultra-fast on low-bandwidth mobile networks using Cloudflare Workers.

How we built it

• AI Integration: Integrated Google Gemini API for semantic request processing and credential analysis.
• Architecture: Edge-native backend running on Cloudflare Workers deployed at https://trust-fix.nlk-apps.workers.dev.
• Database & Auth: Supabase (PostgreSQL) handling dynamic data persistence and Row Level Security (RLS).
• Frontend: Responsive web application designed with Lovable and styled with Tailwind CSS.

Challenges we overcame

• Network Optimization: Designing an edge UI that maintains high performance and fast AI inference under variable mobile network speeds.
• Trust Schema Rules: Structuring relational verification logic in Supabase without introducing setup friction for non-technical tradespeople.

Accomplishments that we're proud of

• Successfully integrating edge-computed microservices with Google Gemini AI.
• Creating a practical tool that addresses real-world economic access and safety for artisans and homeowners.

What we learned

• Deploying serverless AI logic at the edge using Cloudflare Workers and Gemini API.
• Optimizing client payloads for constrained mobile environments.

What's next for TrustFix

• Escrow Payments: Integrating mobile money (MTN MoMo / Orange Money) payment flows upon job completion.
• Voice Requests: Enabling voice-to-text service inquiries in local dialects powered by Gemini.
