King Wash project

King Wash was my first side project to reach full production, a home car detailing service with a completely digital experience. The vision was to make high-quality vehicle care accessible anywhere, whether customers were at home, at work, or shopping.

To achieve this, I designed and implemented a full booking ecosystem that connected customers with the service in a simple, transparent, and professional way. Beyond just building a website, this project became a fully operational business where technology, branding, and real-world service delivery worked hand in hand.

My Role

End-to-End Product Development: Took the idea from concept to production, designing both the digital platform and the business workflows.

Frontend Development: Built a responsive, customer-facing website where users could explore services, packages, and guarantees, and complete bookings online.

API Development: Created a backend API using Laravel Lumen to handle reservations, customer data, and service requests efficiently.

Dashboard Application: Developed a standalone dashboard for company staff to manage bookings, schedules, and customer communications in real time.

Business & Brand Building: Defined the company’s values, trust policies (satisfaction guarantee, rain guarantee, pay-after-service), and branding to create customer loyalty.

Core Features

Booking System: Customers could select individual services or bundled packages, schedule appointments, and manage their reservations online.

Operational Dashboard: Internal web app to manage bookings, assign staff, and track service completion.

API Architecture: Lightweight Laravel Lumen backend enabling communication between the website, dashboard, and booking engine.

Service Guarantees: Built-in policies (satisfaction guarantee, rain guarantee, no upfront payment) to inspire customer trust.

Eco-Friendly Innovation: Implemented waterless wash techniques with biodegradable products to differentiate the service.

Mobile-Optimized Experience: Designed the platform to be fast and simple on mobile, since most users booked on the go.

Impact

Production-Ready Delivery: As my first side project to go live, King Wash validated my ability to design, build, and launch a complete digital product independently.

Digital + Physical Integration: Successfully connected a booking platform with real-world service delivery, demonstrating end-to-end product ownership.

Customer Trust & Growth: Clear guarantees and user-friendly booking increased adoption and built loyalty among early clients.

Foundational Learning: Provided invaluable experience in full-stack development, API design, and system architecture while managing the realities of running a business.

Sustainability Value: Positioned the brand as eco-conscious, turning environmental responsibility into a competitive advantage.
