Flutter (iOS) developer for implementing new features for the upcoming app release

Hi,

I am a senior developer of mobile applications with extensive experience.

Thank you for sharing the detailed requirements for version 1.3.0. I’ve reviewed the document and based on the provided feature list, made the following assessment:

Scope Review & Time Estimation
New Features
1. Continue Watching (resume modal, persistence, native dialog)
… ~ 6–8 hours

2. “New” Label on Video Thumbnails (Figma-based UI work)
~ 2–3 hours

3. Favorite Videos (add/remove, category, UI feedback, persistence)
~ 6–8 hours

4. Thumbs Up (like/unlike, count update, backend sync)
~4–6 hours

5. Downloads & Offline Video Access:
o Download manager & local storage ( ~7 - 8 hours )
o App-only access (sandboxed files) ( ~2 - 3 hours )
o Online/offline category logic ( ~3 - 4 hours )
o Empty-state handling ( ~2 - 3 hours )
~ 14–18 hours

Bug Fixes
1. Rating Pop-up Event Trigger from Video Screen
~ 2–3 hours

2. Video Player Performance & UX Improvements
(Transition handling, interaction stability, playback smoothness)

~ 6–10 hours

Analytics & Event Tracking
• Implementing tracking events for all new features
~ 3–4 hours

Total Estimated Effort

~43–60 hours (more precisely after detailed acquaintance with the project)

This estimate assumes:

• Backend APIs are fully functional and documented
• Figma designs are finalized
• No major architectural refactoring is required
• iOS-only Flutter support (as requested)

If needed, I can also provide:
• A phased delivery plan
• Risk assessment for the video player improvements
• Post-release support estimate

My rate is 30$

Looking forward to discussing next steps.

Best regards,
Roman

Hello! I am an experienced Flutter developer and can help prepare your app for its upcoming release.

I have reviewed the Google Doc with detailed requirements and am ready to implement the listed features and fix existing bugs according to your specifications. Unfortunately, I do not have access to the internal document “app events for tracking” https://docs.google.com/spreadsheets/d/19owUz2oz8MdLELNjpPHjn95GgU1Z-_TfPjVEXDY3kI0/edit?usp=drive_link

Preliminary estimate:

Implementation of features + bug fixes for the release of a “simple application”: 100 hours and $2,500.

Timeframe: approximately 3 weeks.

I would be happy to discuss further steps and details.
