What we build
- Multi-tenant SaaS platforms with tenant management, role-based access and participant-facing dashboards
- APIs and integrations between CRMs, ERPs, identity providers and your own platform
- Platform foundations such as centralized identity, event-driven architecture and shared services across product lines
- Legacy takeovers, where we inherit an undocumented system, stabilize it, and move it forward
Stack
TypeScript, Node.js, React and Next.js; Java; C# and .NET; PostgreSQL and MongoDB; Kafka and event-driven architecture; SSO and modern authentication.
Examples
- For a US fintech, a Salt Square team works as the core engineering group on a multi-tenant retirement platform that has reached live internal production use, with the legacy platform scheduled for shutdown.
- For a global digital music company, a senior strike team delivered one identity platform across seven products and stood up a new platform-engineering function.
- For a 130-clinic Med Spa chain, we took over a legacy system and delivered 24/7 digital booking, then took ownership of the marketing site and CMS.
How we work
Small, senior teams that join your rituals, ship in short increments and write things down. Salt Square leadership stays close to every engagement.
