Stratumn
Overview
Stratumn is an enterprise workflow management platform used by Sia-Partners, a global consulting firm, to orchestrate complex client-facing financial processes with full audit trails and integrations.
The Problem
The existing platform had grown organically across multiple frontend codebases and had no consistent state management strategy. Client integrations — including the Mastercom Extended API for financial data — were built ad hoc, leading to fragile pipelines and slow delivery cycles. The engineering team was spending more time debugging integration failures than shipping features.
Approach
Introduced Redux Toolkit for the React codebase and Pinia for the Vue 3 module, establishing a consistent state management pattern across both surfaces. Shared design tokens and component conventions reduced context-switching for developers working across both stacks.
Owned the Mastercom Extended API integration from contract review through to production. Built a NestJS service layer with RabbitMQ-backed event handling to decouple the integration from the core application, making retries and error handling explicit rather than implicit.
Introduced structured PR templates, architectural decision records (ADRs), and weekly code review sessions for two junior developers. This created a feedback loop that improved code quality measurably over the six-month engagement.
