iOS and Android developer for creating a store for an existing application

We are a team that has already launched a mobile application. Now we want to add a store with video tutorials: free, paid, and subscription-based. The store is an educational section where users can watch video tutorials directly in the app.

📱 We are looking for:

•    iOS developer (Swift)

•    Android developer (Kotlin or Java)

If you have a team of 2 people — great!

💼 What needs to be done:

•    Implement the “Store” section according to the ready design (Figma)

•    Lesson categories: free / paid / subscription only

•    Lesson preview (video player) and transition to purchase

•    Integration with Apple In-App Purchase / Google Billing

•    Filtering: difficulty level, topic, type

•    Ability to save lessons for offline viewing

•    Implementation of “favorites” and progress tracking (watched/not watched)

•    Lesson languages: manual selection and device language detection

•    Lessons are simply videos + description + “buy/watch” button + video preview

✅ Development should be done locally on your side — as a separate application. It is important for us to see your work live: you send a build or a video showing how everything works. After that, we pass your code to our lead developer for integration into the main application.

🔄 Future prospects:

•    Accumulating points for regular logins (loyalty system)

•    Unlocking bonus lessons for activity

•    Promo mechanics and upsell blocks (like “buy a course with a discount until midnight”)

•    Basic built-in analytics (views, clicks, purchases)

🧪 Testing and bug fixes:

•    You provide a build (TestFlight / .apk) for preliminary testing.

•    After testing, we send a list of corrections and bugs — you make adjustments.

•    The final calculation occurs after we receive a stable working module without critical bugs. Important: bug fixes within the scope of assigned tasks and logic are included in the cost.

❗️ Important:

•    You do not need to work with video editors, Metal, GLSL, or other “graphic hell”

•    You only work with the store interface and logic

•    Ultimately, your code will be embedded into the main application (our side will handle integration)

💬 What we expect from you at this moment if you are interested:

•    Experience in iOS or Android development

•    Understanding of Firebase / REST API / offline storage

•    Links to projects where you did something similar

•    Development timeline for MVP

•    Timeframes in which you can implement the store

•    Cost for the work (fixed / hourly / phased)

At the beginning of your response, write the word “penguin” — this shows that you have truly read the task and are not just spamming your resume.
