Chrome Extension Development (MV3)Mahmoud Elmaandy
I build and maintain production Chrome extensions from scratch or on existing codebases.
What I cover:
Manifest V3 architecture (service workers, content scripts, background messaging)
LinkedIn DOM automation and scraping pipelines
API integration and data sync (Firebase, Supabase, REST APIs)
React / Vue UI inside extensions
XHR/fetch interception and bridging
Auth flows, subscription validation, JWT refresh
Performance optimization on long-running extension jobs
Arabic RTL + English localization
