Course overview

Car rental businesses today compete on convenience and how quickly they respond. Most customers browse promotions on their phones, message the shop on LINE and expect to book, pay and get a confirmation straight away, even outside opening hours. Many owners still answer every chat by hand, check every transfer slip themselves and write customer details in a notebook, which wastes time, leaves them exposed to fake slips and scatters customer data.

This course is designed for business owners who do not need to know how to code. Claude Code acts as the programming assistant: learners give the instructions, check the results and make the decisions, while the AI writes the code. Over three days learners build the DriveEasy Car Rental Platform prototype with sample data: a promotion website with Next.js and Tailwind CSS, a booking and vehicle issue system on Supabase, an admin dashboard, and a LINE Official Account that answers customers automatically and verifies payment slips through a slip verification API. Learners finish with a working prototype online and know how to ask the AI to keep improving it. (3 days, 6 hours per day, 18 hours in total, Beginner level.)

Curriculum

Course Details

This course runs for 3 days, 6 hours per day (18 hours in total, 09:00-16:00), as a hands-on workshop offered both as a public class and in-house. Beginner level. Learners build one prototype, the DriveEasy Car Rental Platform, across all three days using sample data. Day 1 builds the promotion website and publishes it on Vercel, Day 2 adds bookings, vehicle issue reports and an admin dashboard on Supabase, and Day 3 connects LINE OA

to answer customers, send PromptPay QR payment requests and verify slips automatically. Unlike Build Business Apps with Claude Code, it follows one car rental scenario from the website through to taking payments on LINE. Learners use their own paid Claude plan and their own accounts for external services. The course focuses on a working prototype (MVP), so it does not cover writing code line by line, credit card payment gateways, accounting and tax systems, GPS vehicle tracking or installable mobile apps.
