Web2 · Service SaaS platform development

Multi-tenant SaaS platforms built to pass an enterprise security review: tenant isolation, SSO and SCIM, audit logs, billing and infrastructure as code.

In short

A SaaS platform serves many customers from one system while keeping each customer's data separate. We build multi-tenant platforms in TypeScript and Go on Postgres and AWS, with the things enterprise buyers ask for — single sign-on, user provisioning, audit logs, tenant isolation — designed in from the start rather than added during a procurement deadline.

SaaS platform architecture: web app, SSO, API, services, queue and Postgres with tenant isolation
When you need it

Signs this is the right service

  • You are building a first version that has to be credible to paying customers.
  • An enterprise deal depends on SSO, SCIM or an audit log you do not have.
  • Tenant separation relies on every query remembering a filter.
  • The product works and the platform underneath it is slowing every release.
What's included

What you get

Tenant isolation

Separation enforced at the data layer, with automated tests that try to read across tenants and must fail.

Identity and access

SAML and OIDC single sign-on, SCIM provisioning, and role-based permissions treated as product features.

Audit logging

Structured events for every sensitive action, retained to match your contracts and exportable for a customer's auditor.

Billing and metering

Subscription and usage-based billing with idempotent event handling, so a retried webhook never double-charges.

Infrastructure and delivery

AWS defined in Terraform, CI/CD with preview environments, dashboards and alerts in place before launch.

How we deliver it

The process

  1. 01

    Discovery

    Two weeks to scope, list the risks and agree what the first release must do.

  2. 02

    Architecture

    Data model, integration map, threat model and a monthly cost estimate, written down and yours to keep.

  3. 03

    Build in two-week cycles

    Against a live environment from the first cycle, with every change reviewed by a second engineer.

  4. 04

    Launch and hand over

    Load testing, runbooks, and either a handover or a team that stays on.

Questions

SaaS platform development: common questions

Do you build the front end as well?

Yes. The same team builds the web application, the APIs and the infrastructure, which avoids the gaps that appear between separate vendors.

Can you work inside our existing codebase?

Yes. As a dedicated pod we work in your repository, with your review process and your definition of done.

How do you handle security reviews from our customers?

By building what they ask about — isolation, SSO, audit logs, encryption, access controls — and documenting it, so the questionnaire can be answered with evidence.

Who owns the code and the cloud account?

You do. We work in your repository and your AWS account from the first commit.
