The Problem
Gifting is one of the most natural human expressions of connection. People love surprising friends, family, and colleagues with food, gifts, services, and experiences.
However, the current experience is fragmented:
- People rely on multiple apps and coordination tools
- Most gifting defaults to cash transfers, losing emotional intent
- Real-world fulfillment is disconnected from digital intent
At the same time, millions of local businesses globally — from restaurants and food vendors to salons, hotels, and service providers — struggle to reach customers consistently without expensive marketing platforms or technical infrastructure.
This creates a gap between intentional giving and local business access to demand.
What I Built
Treat is a global gifting platform that allows anyone to send meaningful real-world experiences to people they care about.
Instead of sending money or generic gift cards, users send:
- Food from local restaurants
- Services (spa, salon, experiences)
- Physical goods from nearby merchants
Recipients receive a secure link via SMS, claim their treat, and redeem it at participating merchants.
Treat is designed so that:
- Merchants get visibility at zero marketing cost
- Senders create meaningful moments instead of transactions
- Recipients enjoy flexible, low-friction redemption

How I Built It (AWS + Vercel Architecture)
Treat is a cloud-native distributed system designed for scale and real-world transaction workflows.
Frontend (Vercel)
- Built with React + Vite
- Deployed on Vercel via GitHub integration
- Handles user experience for sending, claiming, and managing treats
Backend (AWS)
- Built with Ruby on Rails API
- Deployed on AWS ECS Fargate (containerized services)
- Designed as a decoupled API layer for web + future mobile clients
Database Layer
- Amazon Aurora PostgreSQL
- Stores users, merchants, payments, claims, and transaction state
Payments
- Paystack (primary in supported regions)
- Handles secure card and mobile money payments
- Supports instant merchant settlement after verification
Communications
- SMS + Email notifications power:
- Treat delivery
- Claim flows
- OTP verification
- Merchant alerts
Key Workflow
- Sender purchases a treat from a merchant
- Recipient receives SMS link instantly
- Recipient claims and verifies identity (OTP-based security layer)
- Merchant is notified and prepares fulfillment
- After verification at merchant location:
- Payment is released instantly
- Treat is served
Challenges I Ran Into
1. Designing a 3-sided marketplace flow
Unlike traditional e-commerce, Treat requires coordination between:
- Sender
- Recipient
- Merchant
This meant designing a system where emotional gifting and transactional accuracy coexist.
2. Payments and settlement complexity
A major challenge was ensuring:
- Low friction checkout for senders
- Instant payout to merchants after verification
- Cross-provider payment consistency across countries
This required integrating regional payment providers and limiting rollout to supported markets.
3. Real-world redemption vs digital intent
Bridging digital gifting with physical merchant redemption required careful design of:
- OTP verification flows
- QR-based validation
- Merchant-assisted and self-checkout flows
What I’m Proud Of
- Treat is now live and operational at: https://www.sendatreat.app/
- Active deployment across multiple supported regions
- Fully working end-to-end gifting flow (send → claim → redeem → payout)
- Early adoption by local merchants and testers
- Built a system that supports real-world gifting, not just digital transactions
What I Learned
Building Treat reinforced that:
- Gifting is emotional, not transactional
- UX matters as much as infrastructure in real-world systems
- Local businesses thrive when embedded into personal moments, not just marketplaces
What’s Next
- Expand to more countries and payment providers
- Mobile app (iOS + Android) rollout
- WhatsApp + richer notification channels
- Delivery partnerships for non-pickup experiences
- Corporate gifting and rewards integration
Ultimately, Treat aims to become the global infrastructure for meaningful gifting and local business discovery.
