I’m Nikhil Shrestha (nikhilshrestha369), a Flutter developer from Bhaktapur, Nepal. I build production Flutter apps for Android, iOS, Google TV and POS from one Dart codebase, and I publish open-source tools like ai_video_editor on pub.dev for other Flutter developers. 4+ years, 9+ apps shipped, open to remote roles.
Open source: ai_video_editor
ai_video_editor is my CapCut-style video editor package for Flutter with free, on-device AI. Edit by voice or text with AI Edit, cut AI Shorts from the best moments, generate Whisper captions in 12 languages, run a local Qwen 2.5 language model via MediaPipe, remove backgrounds with ML Kit, and export up to 4K / 60 fps through FFmpeg. MIT licensed, for Android and iOS: 106 Dart files, 22K+ lines and 33 test files.

Open source: flutter_stream_buffer
flutter_stream_buffer is my frame-batched text streaming package for Flutter. Give it any stream of text deltas, such as an AI response, live captions or a log tail, and it keeps every chunk in order and delivers one combined snapshot per display frame. Cancellation and errors keep the partial text, restarts ignore late events from the old stream, and a size limit rejects oversized chunks. MIT licensed, 160 of 160 points on pub.dev, for Android, iOS, web, Windows, Linux and macOS.

What I’ve engineered
- Thermal printing over sockets: socket-based bill printing for high-speed thermal receipt printers on POS hardware.
- Google TV experiences: remote and D-pad navigation, lean-back large-screen UI and smooth media playback.
- Real-time feeds and chat: a TikTok-style short-video feed and live chat over WebSockets.
- Augmented reality: AR SDK integrations inside production apps.
- Live maps and tracking: Google Maps live location tracking, geocoding and route optimisation.
- On-device AI video: Whisper captions, ML Kit segmentation and a local LLM in ai_video_editor.
- Release ownership: app signing, iOS provisioning, Play Console and App Store submissions, crash monitoring.
- APIs behind the apps: Node.js and Express REST APIs with JWT auth and tuned MongoDB indexes.
