I already own the Wowonder timeline source and need a developer who can extend it in three focused areas before handing back a fully compiled, ready-to-publish script. 1) Private messaging button I want a native “Message” action on timelines so users can jump straight into one-to-one chats. This replaces the need for Live Streaming or Story-like additions; the emphasis is a clean, reliable private-messaging flow that feels built-in, not bolted-on. 2) New ad platform integration Integrate my chosen monetisation SDK (I’ll supply the credentials and docs) and wire up the ad unit(s) so banners, interstitials or any supported format actually render inside the app. The integration must respect Wowonder’s existing codebase, keep load times light, and give me a single place in the code to switch IDs or turn ads on/off. 3) Post size overhaul The current square crop is limiting. Replace it with a “user-friendly” custom dimension logic: instead of hard-coding 400 × 400, 600 × 600 or 800 × 800, detect the image ratio and scale intelligently so wider photos stay wide and tall photos stay tall, while still fitting the feed neatly. Deliverables • Modified Android and web source files with all three changes implemented • Clear build/installation instructions so I can compile and deploy without further tweaks • A brief TXT or PDF changelog listing every file you touched When everything is working exactly as above on my test server, I’ll release the payment in full and you can forward the final packaged script.
