Automating Architectural Governance: How a Scaling Neobank Unified DevEx and Regulatory Alignment
How a fast-scaling digital bank partnered with Build Circle to integrate automated Architecture Decision Records directly into developer pull requests, eliminating architectural drift, preventing expensive rework, and protecting regulatory compliance at pace.
“By integrating automated ADRs directly into our development workflow, we’ve bridged the gap between autonomy and alignment. Our engineers can now move faster without compromising on compliance or architectural integrity. It’s been a real game-changer for how we build and scale.”

The Challenge
Rapid engineering expansion versus architectural coherence in regulated banking
Rapid commercial growth brought increasing complexity to the Neobank’s core infrastructure, regulatory requirements, and engineering headcount. To sustain momentum, the organisation scaled autonomous squads, but decentralised delivery introduced significant architectural fragmentation:
- The alignment gap: Autonomous teams made independent implementation choices, making it difficult to maintain shared alignment with enterprise-wide technical and security standards.
- Hidden architectural decisions: Vital Architecture Decision Records (ADRs) were easily overlooked during daily coding. Engineers often had no visibility into previous architectural determinations that affected their components.
- Rework and non-compliance risks: Architectural deviations were frequently caught late in the delivery pipeline or during audit checks. This late-stage discovery created conflicts, required costly code rewrites, and introduced compliance vulnerabilities within a heavily regulated banking environment.
The Neobank needed an automated mechanism to bridge developer autonomy with centralised standards, delivering the right architectural context directly into existing development workflows without adding administrative friction.
The Solution
Context-aware ADR automation embedded directly into Git pull requests
Build Circle designed, built, and deployed an automated ADR integration system that bridges architectural knowledge with daily code authoring:
1. Automated pull-request interrogation
- Continuous Git workflow monitoring: Engineered an intelligent integration engine that listens to pull request events across the bank’s distributed repositories.
- Impact surface analysis: Automatically evaluates proposed code changes to identify interactions with existing technical policies, security guardrails, or architectural blueprints.
2. Contextual in-workflow delivery
- Zero-friction context sharing: Injects direct links and summaries of relevant ADRs straight into pull request discussions at the moment of review, eliminating the need for developers to search external wikis or documentation platforms.
- Proactive misalignment alerts: Flags potential architectural divergence before code is merged, enabling developers to adapt implementations early and avoid costly refactoring.
3. Frictionless Developer Experience (DevEx)
- Native tooling adoption: Built to blend seamlessly into established developer habits, driving high organic adoption across teams without requiring additional training or workflow adjustments.
- Empowered autonomous teams: Equipped developers with instant architectural clarity, allowing individual teams to ship rapidly while remaining confident in their adherence to bank-wide standards.
Business Outcome
Reduced technical rework, elevated developer morale, and robust auditability
- Eliminated architectural drift: Prevented conflicting architectural patterns across independent teams, ensuring the bank’s digital infrastructure scales coherently.
- Substantial reduction in rework: Caught architectural deviations and compliance risks at the pull request stage, saving weeks of retrospective remediation and code rework.
- Elevated Developer Experience (DevEx): Replaced manual, bureaucratic governance checkpoints with proactive, automated context, creating a more satisfying and efficient environment for engineers.
- Bulletproof audit and compliance visibility: Provided continuous, automated adherence to regulated banking standards, substantially lowering exposure to governance and audit penalties.
- Scalable delivery foundation: Established a proven internal developer tooling pattern that enables the Neobank to onboard new engineering teams rapidly without diluting architectural integrity.
