Key Takeaways

  • Include 2-4 published apps in your portfolio with links, screenshots, and descriptions of your role.
  • Highlight store performance metrics like downloads and ratings, if permissible, to showcase your app's success.
  • Provide code samples on GitHub that demonstrate your architectural choices and testing practices.
  • Create a demo video or GIF for each app to facilitate easy evaluation without requiring installation.
  • Ensure your resume, GitHub, and portfolio align in terms of platforms, architecture patterns, and featured apps for a cohesive narrative.

Mobile development is one of the few disciplines where you can point a recruiter directly to a live app on the App Store or Google Play - use that. A portfolio ties your published apps, code, and store metrics together in one place. Pair this with How to Build a Professional Portfolio and GitHub Portfolio Optimization.

What to Include

What to include Why
2-4 published apps App Store/Google Play links, screenshots, and a short description of your role on each
Store performance downloads, ratings, or retention if you are allowed to share them
Code samples GitHub repos showing architecture (MVVM, Clean Architecture), state management, and testing
Platform-specific skills Swift/SwiftUI or Kotlin/Jetpack Compose, or cross-platform (Flutter, React Native) depending on your specialty
A demo video or GIF a 15-30 second screen recording of key app flows for anyone who will not install the app

Frame Shipping, Not Just Code

Anyone can show a code sample - what stands out is evidence you can ship and maintain a real product. For each app:

  1. The problem it solves - one sentence on the user need
  2. Your specific contribution - especially if it was a team project (which features, which architecture decisions)
  3. What happened after launch - store rating, download milestones, a crash-rate improvement, or a performance fix you shipped

Where to Host It

  • GitHub for code, with clean READMEs and screenshots
  • A personal site via the TailorCV portfolio builder - to link store pages, demo videos, and code together
  • Direct links to your App Store and Google Play listings, not just screenshots of them

Keep Your Resume and Portfolio in Sync

Your resume, GitHub, and portfolio should tell the same story - same platforms, same architecture patterns, same headline apps - just at different levels of depth. Lock the resume down first with the ATS score checker and an ATS-friendly template, then mirror that positioning in your portfolio. See How to Add Your Portfolio Link to Your Resume for placing the link correctly.

Common Mistakes

  • Screenshots with no live link or demo video - reviewers rarely install unfamiliar apps
  • Listing "built an app" with no mention of your specific role on a team project
  • Outdated apps pulled from the store with dead links still in your portfolio
  • No testing evidence - unit or UI tests are increasingly expected, even for small apps

Pro Tips

  • Record a short screen capture for every app - it removes the friction of installing to evaluate your work
  • Include one app that handles a hard technical problem (offline sync, background processing, complex animations)
  • Generate your portfolio shell from your resume with the portfolio builder and embed your demo videos and store links

Crafting Compelling Case Studies

One of the best ways to showcase your skills as a mobile app developer is through detailed case studies. These narratives provide insights into your problem-solving abilities and the impact of your work. Here's how to create compelling case studies for your portfolio:

  1. Select Projects Wisely: Choose projects that highlight a range of skills. Focus on those that had significant challenges or required innovative solutions. If you have multiple projects, consider selecting a mix of personal, freelance, and professional work.

  2. Structure Your Case Study:

Section What goes in it
Project Overview Briefly describe the project, including its purpose and target audience
Your Role Clearly outline your responsibilities and contributions
Challenges Faced Discuss any obstacles you encountered and how you addressed them
Solutions Implemented Highlight the technologies, frameworks, and methodologies you used
Results and Metrics Provide quantifiable outcomes (e.g., user engagement, downloads, or revenue) to demonstrate the success of your project

  1. Visuals and Demonstrations: Include screenshots, videos, or links to the app (if available) to provide visual context. This not only makes your case study more engaging but also helps potential employers visualize your work.

  2. Reflect on Learning: Conclude with a brief reflection on what you learned from the project and how it has influenced your development process.

Step-by-Step Guide to Creating a Portfolio Website

Building a portfolio website can seem daunting, but breaking it down into manageable steps can simplify the process. Follow this guide to get your portfolio online:

Turning a resume into a portfolio site

The TailorCV portfolio builder: pick a template, upload an existing CV to auto-fill the sections, then publish a shareable link

You upload the resume you already have and the sections fill themselves in - basics, experience, projects, education - so building the site is editing rather than starting from an empty page.

  1. Choose Your Platform: Decide whether you want to use a website builder (like Wix or Squarespace) or a content management system (like WordPress). For a custom approach, consider using GitHub Pages or a static site generator like Jekyll.

  2. Select a Domain Name: A custom domain name (like yourname.com) enhances your professionalism. Refer to our guide on How to Put Your Portfolio on a Custom Domain for tips on registering and setting up your domain.

  3. Design Your Site: - Homepage: Create a welcoming homepage that introduces you and your work. - Portfolio Section: Dedicate a section to showcase your projects. Each project should have its own page or modal with details and visuals. - About Me: Write a brief bio that highlights your skills, experience, and interests. - Contact Information: Make it easy for potential employers to reach you. Include a contact form or your email address.

  4. Optimize for SEO: Use relevant keywords in your text, image alt tags, and meta descriptions to improve your visibility in search engines.

  5. Test and Launch: Before launching, test your website on different devices and browsers to ensure compatibility. Once you're satisfied, go live!

Frequently Asked Questions

My best work is a private company app I cannot show publicly - what do I do?

Describe the problem, your role, and the architecture without sharing proprietary code, and build one public side project to demonstrate hands-on skill. See Portfolio No Projects and consider using our portfolio builder for guidance.

Should I show native or cross-platform work?

Show whatever matches your target roles. If you know both, lead with your strongest platform and mention the other as a secondary skill. For tips on showcasing your work, check out the Business Analyst Portfolio Guide.

How do I align my resume?

Keep platform names, architecture patterns, and app names consistent across resume and portfolio. You can also use our Free ATS score checker to ensure your resume aligns well with industry standards.
