Manpreet S.

Top Rated Plus Electron developer with 16+ years and 20,000+ hours on Upwork. I build cross-platform desktop apps for Windows, macOS and Linux, specializing in FFmpeg screen recording and video tools, React + TypeScript, and AI features like Whisper transcription. Most recently I designed, built and shipped Cut Video Gaps, my own Electron app for macOS that removes silences and bad takes from video using on-device Whisper AI and FFmpeg, and exports directly to Final Cut Pro, Premiere Pro and After Effects. WHAT I BUILD • Electron desktop apps for Windows, macOS and Linux • Screen recording, video editing and media apps with FFmpeg and OpenCV • On-device and cloud AI features with Whisper and OpenAI: transcription, silence and filler-word removal, AI notes • Chrome extensions, from idea to published Chrome Web Store listing • Native OS integration: file system, system audio, permissions, background processes and IPC WHAT I OWN END TO END Architecture, development, native integration, performance tuning, installers, code signing, auto-updates and release automation. I have shipped my own products, so I think about the whole product, not just the ticket in front of me. FOCUSED FIXES, TOO Not every project needs a full build. I also take short, well-defined jobs: • Code signing and notarization for macOS and Windows • Auto-update setup and release pipelines • Electron version upgrades and security fixes • FFmpeg bugs, slow exports and media performance problems • Chrome extension fixes and Manifest V3 migrations RECENT WORK • Cut Video Gaps: my own Electron video editor with local Whisper AI and FFmpeg, exporting to Final Cut Pro, Premiere Pro and After Effects • Teamly Capture: Electron screen recorder and video messaging app with FFmpeg and AI editing • VideoNotebook: Chrome extension that writes AI notes while users watch videos • FormatPro: my own Chrome extension for formatting text on LinkedIn and Upwork TECH Electron, React, TypeScript, Node.js, FFmpeg, OpenCV, Whisper, OpenAI, Python, Firebase, GraphQL, Chrome Extensions HOW I WORK Available now. I work best as the long-term desktop lead on a product, owning the Electron codebase across releases, and I am happy to start with a small paid task so you can see how I work first.
