The Problem

The firm was manually connecting their tools — Google Forms feeding into spreadsheets, Stripe events handled by hand, Slack notifications copy-pasted from dashboards. Every new automation request went to the dev team. They needed a self-serve internal platform where non-engineers could wire up workflows visually, without writing a single line of code.

Our Approach
  1. 01Visual React Flow canvas — drag, drop, and connect trigger/action nodes with no-code
  2. 02Trigger nodes for Webhook, Google Form, Stripe events, and manual runs
  3. 03AI action nodes integrating OpenAI, Claude, and Gemini for in-workflow intelligence
  4. 04Discord and Slack messaging nodes for automated team notifications
  5. 05Inngest-powered background job execution with retries, queuing, and concurrency control
  6. 06Full SaaS layer: Better Auth authentication, Polar subscription plans, and usage paywalls
  7. 07Sentry error tracking with AI-assisted monitoring and CodeRabbit PR review workflow
  8. 08End-to-end type safety with TypeScript + tRPC across client and server
The Solution

A production-grade internal automation platform where the firm's ops team visually builds workflows on a drag-and-drop canvas — connecting Stripe events to Slack alerts, Google Form submissions to AI summarisers, webhooks to HTTP endpoints — all executing reliably in the background via Inngest. Non-engineers ship automations in minutes instead of filing dev tickets.

The Outcome

Replaced a backlog of recurring automation requests overnight. The ops team now builds and deploys workflows independently. Background job reliability hit 99.9% with Inngest's retry engine, and Sentry + AI monitoring catches workflow failures before anyone notices.
