# Screen recording platform rewrites

Haris Muhibić was tech lead for three v2 rewrites of a screenshot and screen-recording SaaS (desktop app, web dashboard and browser extension), and moved its video encoding onto serverless GPUs.

- Role: Tech lead and release owner
- When: 2022 – 2026
- Stack: Electron, React, TypeScript, Next.js, Chrome MV3, Node.js native addons, ffmpeg, AWS Lambda, serverless GPUs

## Desktop app (Electron)

I was the release owner from the first build through version 1.8.

- **Releases:** auto-update with beta channels, Windows code signing and macOS notarisation.
- **Native modules:** packaged for both x64 and arm64.
- **Recording:** macOS screen recording through native capture, a rewritten Windows recorder, cursor and click highlighting from global input hooks, and Do Not Disturb while recording.
- **Server-side processing:** cropping and GIF and MP4 conversion moved off the user's machine.

## Web dashboard (Next.js)

I started the rewrite and set its architecture: layout, authentication handed over from the old app, drop privacy and self-destruct, team branding, search, folders and billing add-ons. It reached production through an opt-in beta flag while the old dashboard kept running.

## Browser extension (Manifest V3)

Recording with pause and resume, camera overlay, injected controls and full-page "scrolling" screenshots that handle the nested scroll containers of React apps. Permissions were trimmed to pass Chrome Web Store review.

## Media pipeline

- **Then:** ffmpeg on Lambda, with palette-optimised GIFs and progress reported back to the desktop app.
- **Now:** encoding on serverless NVIDIA GPUs, with a circuit breaker, a CPU fallback, a watchdog for hung processes and output checks before publishing.

## Open source

A maintained fork of a global keyboard and mouse hook that still builds on modern Electron, despite V8 API removals and ABI changes.
