Android iOS Spam Message Blocker

I need an experienced mobile application developer skilled in both Android and iOS application development to create a reliable, user-friendly and efficient application that provides automatic spam message blocking and word filtering.

Briefly, the working logic of the application is as follows: only the words that are wanted to be blocked will be written. If these words are included in the incoming SMS, it will be blocked as spam.

Key Features:
- The app should work on both Android and iOS devices.
- The main purpose of the application is to block spam messages and filter out unwanted words.
- The blocking process needs to be automated; a user should not need to manually block each spam message or unwanted word.

Ideal Skills and Experience:
- Proficient in Android and iOS app development.
- Experience in creating privacy-focused applications.
- Familiar with techniques for efficient spam detection and automatic filtering.
- Strong understanding of user-interface design and user-experience practices for optimal app usability.
- Previous work on similar projects highly appreciated.

If you're up for a challenge and can deliver a high-quality, effective app, I'd love to hear from you!
