App Developer Needed – Simple Video Editing App (Auto Cut Silence for Talking Reels)

I’m looking for an experienced app developer to build a simple, clean video editing app focused on one specific job:

Taking raw talking-head videos (Instagram Reels, short-form content, talking videos) and automatically removing dead space, pauses, and silence between sentences.

The goal is speed and simplicity, not a full video editor.

Core Functionality
Main Feature:

User uploads a raw talking video

The app automatically detects:

Silence
Long pauses
Dead space between sentences
Unnecessary gaps in speech

The app then:

Cuts those sections automatically
Creates a tighter, faster-paced final video
Keeps natural conversation flow (not robotic or too aggressive)
Export Requirements:
Export final video in high quality
No noticeable quality loss
Optimized for Instagram Reels / TikTok / Facebook short-form content
Fast rendering speed preferred
Simple UI Requirements

I want this to be:

Very clean
Very beginner-friendly
Minimal buttons
Fast workflow

Ideal flow:

Upload video
Click “Auto Cut”
Preview result
Export finished video

That’s it.

Nice-to-Have Features (Optional but valuable)
Adjustable silence sensitivity slider
Option for “light cut” vs “aggressive cut”
Batch processing for multiple videos
Desktop version preferred (Windows/Mac), but open to best recommendation
Potential future upgrade path for captions/subtitles
What I Need From You

Please include:

What platform you’d recommend building this on
Your experience with video processing/editing apps
Examples of similar apps/tools you’ve built
Estimated timeline
Estimated cost
Tech stack you’d use
Important

I care more about reliability and speed than flashy design.

This needs to solve one problem extremely well:
Turning long raw talking videos into clean, fast-paced short-form content quickly.

If you’ve built something similar before, that’s a huge plus.
