PROJECT OVERVIEW

Project Overview

CLIENT

B2B SaaS Infrastructure

TIMELINE

10 weeks

ROLE

Full-Stack Architect

Every B2B product needs the same foundational infrastructure - customer workspaces, user permissions, billing, and integrations. Instead of rebuilding this from scratch each time, I created a ready-to-go management platform that any SaaS product can build on top of, saving months of development.

THE CHALLENGE

The Challenge

Multi-Tenancy

Each customer workspace must be fully isolated with its own permission policies - no data or configuration bleed between organizations.

Billing

Support for multiple pricing models - flat subscriptions, usage-based billing, and automatic invoice generation for finance teams.

Webhooks

External integrations need reliable event notifications with guaranteed delivery, automatic retries, and a full log of what was sent and when.

Observability

Production reliability requires full request tracing and performance monitoring so issues are detected and resolved before customers are affected.

THE SOLUTION

The Solution

A production-ready management backbone that handles all the common SaaS infrastructure - workspaces, permissions, billing, and integrations - so product teams can focus on building their unique value.

WORKSPACES

Customer Workspace Management

Create and manage customer workspaces with team invitations, role assignments, and organization-level settings - all from a single admin panel.

RBAC

Granular Permissions

Control exactly what each user can see and do with predefined roles and custom permission sets per workspace - ensuring the right access for every team member.

WEBHOOKS

Integration Event System

Send real-time notifications to external systems when important events happen - with guaranteed delivery, automatic retries, and a complete audit trail.

BILLING

Built-in Billing & Subscriptions

Manage pricing plans, track usage, and generate invoices automatically - one less vendor to integrate and maintain.
