Case Studies

At Grey Colour Systems, we don’t just deliver projects — we solve complex problems, drive transformation, and build long-lasting partnerships. Here are selected case studies showcasing how our secure, agile, and scalable solutions have helped clients achieve measurable success across public and private sectors.

Case Study #1: Transforming Public Sector Services with a Cloud-First Platform

Sector: Public Sector / Government Services
Engagement Duration: 9 months
Team Size: 6 cross-functional consultants
Services Provided: Discovery, Agile Delivery, Cloud Migration, DevSecOps

Challenge

The department operated on outdated, siloed legacy systems that slowed service delivery and made data sharing between units complex and error-prone. A critical need emerged to build a modern, secure platform to digitise citizen-facing services and improve internal operational efficiency.

Our approach

Led a discovery phase to map user journeys, pain points, and system dependencies
Introduced an agile delivery framework aligned with GDS service standards
Architected and deployed a secure, cloud-first microservices platform using Azure
Established CI/CD pipelines with integrated security scanning
Delivered comprehensive documentation and trained in-house teams on platform management

Results

65% improvement in service response time
Migration of 5 legacy apps to cloud infrastructure
Full compliance with Cyber Essentials Plus and ISO 27001
Platform recognised as a model for other departments

“Grey Colour Systems delivered with precision. Their cloud expertise and agile approach helped us modernise critical systems with minimal risk.”

— Permanent Secretary, Citizen Services

Case Study #2: Scaling a FinTech Platform for Rapid Growth

Sector: Financial Services

Engagement Duration: 12 months

Team Size: 4 engineers, 1 UX designer, 1 cloud architect

Services Provided: Software Engineering, Kubernetes, UX/UI, Infrastructure as Code

Challenge

The client’s user base tripled within six months, but the underlying infrastructure could not keep up with performance, uptime, and feature deployment demands. They needed a rapid scale-up of their platform without compromising security or compliance.

Our approach

Assessed existing AWS architecture and performance bottlenecks
Introduced Kubernetes for automated scaling and load balancing
Rebuilt CI/CD workflows using GitHub Actions and Terraform
Conducted security hardening audits and implemented end-to-end encryption
Co-designed a new mobile-first user interface following IBM Design Thinking principles

Results

99.98% uptime achieved with resilient auto-scaling infrastructure
New features deployed 4x faster
FCA-compliant architecture and data governance
Reduced support tickets by 40% post-launch
