Chronomation
Multi-tenant productivity platform with PDF editing and BankID signing as its main pillars
Overview & Vision
Chronomation is a multi-tenant productivity suite. Currently in active development, it targets Swedish SMEs that need streamlined document workflows with legally binding signatures via BankID.
Core Product: PDF Editor & BankID Signing
The platform centers on two pillars: a collaborative PDF editor for creating and annotating documents, and a BankID integration for legally binding digital signatures — critical for contracts and agreements in the Swedish market.
- In-browser PDF editing with annotation and markup tools
- BankID-verified document signing with audit trail
- Multi-tenant workspace isolation and user management
- Automated content generation from work artifacts
Technical Architecture
Built on TanStack Start with React 19, using Neon Postgres with Drizzle ORM for multi-tenant data isolation. The architecture supports per-tenant configuration, role-based access, and edge-deployed middleware for fast response times across Sweden.
- Multi-tenant data model with row-level security in Neon Postgres
- Drizzle ORM for type-safe database queries
- Edge-deployed on Vercel for sub-100ms TTFB
- BankID integration via official Swedish e-ID infrastructure
Build-in-Public Journey
Chronomation is being built publicly through The Builder Coil, documenting architecture decisions, technical challenges, and lessons learned. This transparency serves both as a learning resource for the developer community and as a marketing channel for the product itself.
