Project Overview

Doctors バイト is a mobile platform that simplifies how doctors in Japan find job opportunities, manage schedules, and communicate with hospitals. Designed for busy medical professionals, it centralizes key workflows—job listings, applications, chat, attendance tracking, and calendar management—into one seamless mobile experience.

As the sole product designer, I owned the full design process: defining flows, building wireframes, creating the final UI, and collaborating directly with developers during implementation.

The app’s goal was to provide a professional, trusted, and efficient interface that reflects the reliability of the medical field while remaining user-friendly for doctors managing their careers on the go.

Project Goals

• Centralize job opportunities — Allow doctors to browse, filter, and apply for hospital jobs and part-time shifts easily
• Showcase professional identity — Enable doctors to create detailed, verified profiles highlighting experience and specialization
• Facilitate communication — Integrate real-time chat between doctors and hospital HR teams
• Enhance productivity — Include attendance tracking, shared calendar, and event reminders
• Deliver a clean, trusted UI — Create a professional yet approachable interface tailored to healthcare professionals

Design Approach

Stakeholder-Driven Insights

Collaborated closely with marketing managers who provided context on user behavior and hospital-side needs. These insights revealed challenges like fragmented job listings, unclear workflows, and communication bottlenecks.

Problem-First Thinking

Each design decision was guided by core usability issues identified during discussions—specifically around application friction and delayed communication between doctors and hospitals.

Mobile-First UX

Given doctors’ mobile-first habits, the experience was designed for speed, focus, and clarity: large tap targets, minimal clutter, and logical navigation patterns across key features.

Wireframes & Layout Planning

I created mid-fidelity wireframes in Adobe XD to explore layout and functionality across core user flows. These wireframes helped validate information hierarchy and interaction logic before refining the visuals.

Key Wireframe Screens:

• Doctor Profile with list of Approved Applications
• In-App Chat with Hospital Representatives
• Attendance Logs and Calendar View

Final UI Snapshots

The final interface was designed to inspire trust, clarity, and professionalism, with visuals reflecting the precision of the medical industry and the accessibility of a modern mobile product.

Visual Design Focus:

• Cool, medical-inspired palette (blues, grays, whites) reinforcing trust and calmness
• Readable typography with clean line spacing for clarity on mobile
• Iconography and visual hierarchy supporting quick scanning during busy schedules
• Consistent grid and spacing system for structural balance and simplicity
• Responsive, scalable UI components for future feature growth

Highlighted Screens:

• Seamless Sign-In
• Doctor Profile & Approved Applications
• In-App Chat with Hospital Reps
• Calendar & Event Management
• Job Listings & Filters
• Attendance Logs

The design achieves a balance between professionalism and usability—helping doctors manage opportunities and schedules efficiently while maintaining a polished, brand-aligned aesthetic.

Outcome & Reflection

The final design received strong positive feedback from stakeholders for its intuitive structure, smooth navigation, and visually refined interface. Deliverables included a complete mobile design system and developer-ready assets for scalable implementation.

Collaborating closely with marketing stakeholders gave me deeper insight into user needs from a business and operations perspective. While direct interviews with doctors were not possible at this phase, stakeholder input was effectively translated into practical, user-centered solutions addressing key challenges in job search, scheduling, and communication.

Moving forward, I aim to validate these design decisions through usability testing with doctors, ensuring the app continues to evolve in alignment with real-world workflows and expectations.
