On-Demand Car Wash App

DoorWash – Your car, clean in minutes. On-demand car washing, right where you are.

Inspiration

In busy cities across Nigeria and many other places, people are always on the move with tight daily schedules. Finding time to visit a traditional car wash and wait in long queues has become very difficult. As a result, many car owners end up driving semi-dirty or dusty cars for weeks.

A clear example is my brother-in-law, who is constantly busy and always complains about not having time to properly wash his car. This real-life frustration inspired me to build DoorWash — an on-demand car washing platform that brings professional washers directly to the customer’s doorstep, just like Uber.

What it does

DoorWash is a Progressive Web App (PWA) that connects car owners with trusted local car washers in real-time.

Key features include:

  • Location-based discovery of nearby available washers
  • Quick booking with flexible service options (Exterior, Interior, Full)
  • Wallet system and Direct Pay options (Paystack & Stripe)
  • Real-time tracking of the entire service — from acceptance to arrival, washing, and completion
  • Automatic settlement — payments are automatically released to the washer after job completion and customer confirmation
  • In-app and push notifications
  • Live chat between customer and washer
  • Ratings & reviews with photo proof
  • Complete transaction history and earnings ledger

Users can book a professional car wash in minutes and have it delivered at their preferred location without leaving home or the office.

How we built it

I built the entire application using MeDo.dev, an AI-powered full-stack app builder.

I started by writing all my thoughts on what, how I want the app to be like, then use the prompt optimiser to structure it. Sometimes, I use ChatGPT. Through multiple careful iterations and refinements, I guided the AI to create a fully functional MVP with:

  • Real payment gateway integration (Paystack + Stripe)
  • Wallet system and automatic settlement logic
  • Real-time tracking and status updates
  • Secure backend with transaction ledger
  • Beautiful, mobile-first PWA design
  • Role-based Authentication

Special attention was given to making every flow dynamic and production-ready.

Challenges we ran into

  • Token limitations on the AI platform — I frequently ran out of tokens and had to pause for hours or continue the next day.
  • Implementing complex features like real-time tracking, wallet system, and automatic settlement while keeping the app secure and reliable.
  • Moving from simulated flows to a fully functional system with real payment processing and automatic payouts.

Accomplishments that we're proud of

  • Successfully built a fully functional on-demand marketplace app with real payments and automatic settlement.
  • Integrated wallet system, real-time service tracking, and secure transaction flows.
  • Created a clean, modern, and professional UI/UX that feels like a real-world product.
  • Completed smooth end-to-end journeys for both customers and washers.
  • Built everything using AI in a short time, making it ready for hackathon judging.

What we learned

This project taught me the true power and limitations of AI tools in software development. I discovered that with clear, detailed, and contextual prompting — including design references and specific user flows — AI can produce impressive, high-quality results.

I also improved my prompt engineering skills significantly and learned to use references for more details expecially in design.

What's next for DoorWash

  • Launch the app because it will sell with proper marketing.
  • Improve the wallet withdrawal system for washers
  • Add advanced matching and intelligent scheduling
  • Enhance photo proof of service and quality verification
  • Expand to more cities and additional services (car detailing, interior deep cleaning)
  • Launch native mobile apps (iOS & Android)
  • Add live GPS navigation for washers
