Pet Services Marketplace Platform
MadPaws is an pet services marketplace connecting pet owners with trusted sitters, walkers, and groomers. The platform handles user onboarding, service listings, bookings, payments, and review workflows with strong reliability and scalability requirements.
Project Overview
MadPaws is an pet services marketplace connecting pet owners with trusted sitters, walkers, and groomers. The platform handles user onboarding, service listings, bookings, payments, and review workflows with strong reliability and scalability requirements.
MadPaws is a pet-services marketplace covering onboarding, listings, bookings, payments and reviews at scale. Built on Next.js, Node.js/Express, PostgreSQL, AWS and Redis with reliability and horizontal scale as first-class requirements.
Technical Implementation
Architecture
A modular architecture cleanly separating on-chain programs, low-latency data ingestion, and the user-facing app. On-chain code is written in Rust or Solidity with strict test coverage; off-chain services run on Node.js / Rust backends with Redis and PostgreSQL for hot and durable state respectively, containerized for reproducible deploys.
Smart Contracts
Programs are implemented in Rust with the Anchor framework on Solana, or in Solidity on EVM chains, with strict access control, exhaustive error handling, and gas / compute-unit optimization. Every state transition is covered by unit and integration tests before mainnet deployment.
Performance & Reliability
Where the project is performance-sensitive, the hot path is optimized end-to-end: zero-copy parsing, connection pooling, Redis-backed caches, Jito / Nozomi inclusion for Solana, and careful batching for EVM. Monitoring and alerts cover latency, inclusion rate, and PnL so regressions surface immediately.
