SignawayDocs

The challenge

Signatures only matter if they can be proven later. The platform had to let several companies prepare agreements, invite signers safely, and produce a final PDF that nobody could quietly change afterwards.

What I built

A Laravel 13 application with a React 19 + TypeScript front end rendered through Inertia. Platform admins create companies and invite owners; owners invite their team. Signers follow a protected journey; every action is written to an append-only audit history. Fields are placed on the document in the browser with PDF.js, and a Python worker (pypdf, ReportLab, Pillow) generates the completed PDF and its audit certificate. Authentication uses Laravel Fortify with verified email, TOTP MFA and recovery codes.

Result

A production platform live at signawaydocs.com, with a reproducible Docker environment (PHP 8.4, MySQL 8.4, Node 24, queue, scheduler, Mailpit) and tests.

Highlights

• Laravel 13 + React 19 through Inertia, with invitation-only auth, TOTP MFA and recovery codes
• Browser field placement with PDF.js; Python (pypdf, ReportLab) produces signed PDFs and audit certificates
• Queues, scheduled jobs, a full Docker dev stack and an automated test suite
