Go Expense

Enterprise Financial Workflows at Scale

Backend systems for complex financial workflows, real-time updates, and enterprise-grade permissions.

Overview

Go Expense is an enterprise expense platform with multi-role workflows, third-party integrations, and real-time capabilities.

The challenge

The product required reliable backend systems for financial workflows, role-based access, third-party integrations, and live state updates — without sacrificing correctness.

My approach

Designed REST/GraphQL APIs, serverless workflows, a dynamic rule engine, and scalable worker patterns. Reviewed code with the team and led architecture discussions with stakeholders.

Result

Stronger backend reliability, real-time behavior the product needed, and tighter workflow control for finance teams.
