HI-FI WIREFRAMES

Here is a set of 18 Hi-Fi wireframes showcasing the core user journey and functional logic of the app

PROTOTYPES

After completing all Hi-Fi wireframes, I moved on to prototyping. I created 50+ interactive screens, taking the design better than the MVP level.

The result is a fully functional prototype, ready for real-world testing.
Feel free to explore it using the button below

ORDER CUSTOMIZATION

For example, take the French fries meal, customers are offered additional products to customize their order, such as sauces, toppings, or sides.

This approach empowers users to combine meals with their personal preferences while increasing the overall check size.

The original price was $10, but with selected add-ons, the final price increased to $21, so it boosted by 2.1 times.

This upselling technique proved effective and was consistently applied across all 15 dishes, including 4 drinks. It has not only enhanced the user experience, but also positively impacted business revenue.

CROSS-SELL BLOCK

After a customer places an order, it’s effective to show a confirmation screen highlighting their selected items.

Why? It gives them a moment to double-check the order, and more importantly, it’s an ideal opportunity to introduce a cross-sell block with additional products they might want to add.

It draws their attention one last time before checkout.

In the example video, the customer added one more item during this step. The total increased from $53 to $68, making it a 1.28 times boost in order value.

TIPS FOR CHEF

This is a unique feature I haven’t seen implemented elsewhere, but it has clear potential to benefit the business.

For example, if a chef's standard salary is $4,000, we introduced an option to offer $3,800 + tips instead.

This approach allows the business to save $200 per chef per month, while motivating chefs to improve food quality to earn more through tips.

It’s a win-win-win strategy.

MANUAL TIP BUTTON

In many cases, tip options are limited to fixed percentages, 10%, 20%, 30%, etc. However, this can actually reduce the possibility of leaving tips at all.

Here’s why:
For high-value orders, percentages may feel too high. A customer might want to leave 5%, but without that option, they may skip tipping entirely.

Similarly, if someone wants to leave a specific amount (like $10) but can’t, they’ll often choose a lower sum or nothing at all.

In the example video, the max suggested tip was $21.60 (30%), but the user manually entered $50, more than double. So, this solution is worth it.

IT’S SOLVED FOR GROWTH - NOW FOR USABILITY

INTEGRATED DESIGN FEATURES

[ for user ]

[ 06 / 08 ]

The main goal of this section was to make the UX as user-friendly as possible. Below are problem–solution examples that were identified and implemented to improve the overall user experience.

ORDERS FOR NON-REGISTERED USERS

Problem

no opportunity to make quick orders for non-registered customers, so they can close the app without making the order, or make the order from the competitors

Solution

I created the “Continue as a guest” button with the possibility to insert important delivery data in the checkout screen

Result

not loosing the large number of people while entering the application

ORDER CUSTOMIZATION WITH NOTES

Problem

no opportunity to add extra products or to make some notes

Solution

create extra product screens for each meal/drink and add a field for special notes

Result

a customer makes an order even if they have an allergy to the contained products

WHAT I GOT FROM THE PROJECT

This project gave me valuable experience. As my first full-cycle project, I handled everything myself and came out more confident, ready to take on both user and business challenges.

[ 08 / 08 ]

assimilated how to do each UX design process step in detail

investigated Figma features such as prototyping with variables and conditionals

learned how to reduce time spent on designing similar screens, using the component Figma feature

find out how to cope with obstacles when you work on the project alone
