ASTAA is a mobile application designed for service professionals such as plumbers, painters, electricians, and cleaners to manage jobs, connect with customers, and grow their business digitally.

Building design system.
User research was conducted to understand the daily challenges faced by service providers such as plumbers, electricians, and cleaners. Insights were gathered through informal interview and observations to identify how they find work, manage requests, and communicate with customers in the absence of a digital platform.

Jobs are managed through calls and messages, making planning difficult.
2
Availability is unpredictable, affecting income stability.
3
Providers lack a profile to showcase skills and build trust.

I mapped the job application flow and designed the app’s information architecture before sketching paper wireframes. These were refined into digital wireframes and a low-fidelity prototype to test usability and navigation clarity.
I began by creating storyboards to focus on the most important moments in the service provider’s experience. The story was told through sequential panels and explored from two perspectives: the overall user journey and the in-app interaction flow.
The big picture storyboard presents the service provider’s journey and daily experience.
The close-up storyboard focuses on the app itself, showing screens from profile setup to applying for jobs and tracking earnings.
Next step: creating the application map. My goal here was to make strategic information architecture decisions that would improve overall app navigation. The structure I chose was designed to make things simple and easy.
Here I drew five different versions of how structure of information on a homepage might look like. Then I reviewed all the versions and combined them in the refined one.
The goal was to explore different ideas with wireframes.
I conducted unmoderated usability tests with 5 participants who match Astaa’s target users (service providers such as technicians and freelancers). Participants were asked to complete key tasks using the low-fidelity prototype while sharing their thoughts aloud.
The goal was to identify friction points in core flows such as submitting an offer, accepting direct proposals, completing appointments, and withdrawing earnings.
After analyzing the feedback, I identified recurring themes and usability issues that were refined before moving to high-fidelity designs.

Some users struggled to distinguish between public posts and direct proposals, indicating a need for stronger visual hierarchy and clearer labeling.

In this phase, I transformed the usability study insights into refined high-fidelity designs for Astaa. I focused on improving clarity, strengthening visual hierarchy, and simplifying key flows such as submitting offers, handling direct proposals, and completing jobs. Clear feedback states and stronger action emphasis were introduced to reduce friction and improve user confidence.
I created high-fidelity mockups for all major screens, ensuring consistency in typography, layout, and components. The designs prioritize usability for service providers, making core actions—like making offers, completing tasks, and managing earnings—intuitive and easy to navigate. The result is a polished, production-ready interface.
Through research, usability testing, and iterative design, Astaa evolved into a clearer and more structured experience for service providers. The final prototype simplifies core flows such as submitting offers, managing appointments, and withdrawing earnings, ensuring a smooth and confident user journey.
