Six Mobile Portfolio Designs

I want to refresh my Freelancer.com profile with six separate portfolio pieces, each centred on a different mobile-app tech stack. The stacks that must be featured are Java, Kotlin, React-Native, Expo, Cordova and Swift (Flutter may appear as a supporting framework where it makes sense, but the six listed stacks lead the narrative).

Every piece must follow a clean, professional look—consistent typography, balanced whitespace and a restrained colour palette—yet still feel unique to the specific technology showcased. Within each portfolio item I need three core sections:

• A concise project description that explains what the app does and why that language or framework was chosen.
• A short, genuine client testimonial that reinforces the quality of the work.
• High-resolution app images or mock-ups that immediately show the UI.

No code snippets are required.

Deliverables (one set for each of the six stacks):
1. Final web-ready images sized for Freelancer.com’s portfolio grid.
2. Editable source file (Figma, XD or layered PSD—whichever you prefer).
3. A brief style note so I can keep future additions visually consistent.

I will consider the job complete once all six designs are uploaded to a shared folder, ready for me to place in my profile, and each includes the three mandatory sections above.

Start your bid with "Six Designs" I need it by tomorrow no execuse about the deadline!!! IF you miss it then you will not get paid a penny!! As this is somewhat urgent and I need all editable and type of formats for images as well.. PNG, JPEG
