Overview
Syscon builds FIT, a field-tracking platform integrated with Sage for payroll and expense processing. As the product and its codebase evolved, the engineering team saw an opportunity to move beyond individual AI experimentation and establish a structured approach to AI-assisted development.
Together with Santex, they introduced Claude Code and Claude CoWork into daily engineering workflows, combining AI-powered development with continuous measurement from the start.
The Challenge
FIT had grown across three separate codebases, spanning API, mobile, and ops (the management console), while evolving toward a multi-tenant platform.
That complexity was reflected in the development workflow: PR reviews were lengthy and large, test coverage on the core mobile app was limited, and deployments and architectural decisions lacked an automated record.
The Solution
Santex worked with Syscon to embed AI into the engineering workflow through a phased approach, moving from assisted development toward increasingly autonomous execution.
Claude Code was configured with custom plugins and subagents built around AI Engineering principles, enabling it to turn well-defined tickets into review-ready code while engineers remained in control of validation and delivery.
At the same time, four always-on measurement suites were introduced to continuously evaluate the impact on delivery, quality, releases, and engineering decisions.
CHRONOS
Tracks cycle time from commit to merge.
ARGOS
Monitors test and deployment quality.
SESHAT
Automatically captures what ships in every release.
METIS
Audits architectural decisions and decision churn.
“Building our own plugin and subagents around AI engineering principles turned Claude Code from a helper into a real force multiplier for the team.”

Impact
In six months, AI moved from individual experimentation to a measurable part of Syscon’s engineering system. The result was faster delivery, stronger testing, continuous measurement, and greater visibility into the decisions shaping the product.
