Chrome Extension - Assistance for application users
We are CashDirector, a leading fintech and ERP SaaS platform offering accounting automation and KSeF (Polish e-Invoicing) solutions for SMEs and accountants. We require an experienced Chrome extension developer to create, test, and help publish a browser extension to the Chrome Web Store. The extension will simplify the process for our users to download their KSeF certificate from the government portal and upload it to the CashDirector platform. Key features include a guided step-by-step download process, detection and secure handling of certificate files, REST API integration for uploads, optional validation checks, user feedback, and compliance with Chrome Web Store requirements. The technical stack involves Manifest v3, JavaScript or TypeScript, Chrome APIs, and secure file handling. Deliverables are the working extension, assistance with Chrome Web Store submission, source code, user and technical handover guides. Experience with Chrome extension publication, authentication flows, GDPR, and familiarity with the Polish KSeF system are valuable. The timeline is to start within 1–2 weeks and deliver in 2–4 weeks.
