Reducing Deployment Time from Days to Minutes for Global FinTech Leader
A strategic CI/CD transformation that increased deployment frequency by 400% and eliminated 90% of manual processes
Overview
Our client is a rapidly growing FinTech company processing over $10 billion in transactions annually for more than 5 million customers worldwide. With 200+ developers across 12 teams and a microservices architecture comprising 80+ services, they were experiencing significant challenges with their legacy deployment processes.
As their customer base expanded by 35% year-over-year, the strain on their development and operations teams intensified, making it increasingly difficult to maintain quality while delivering new features at the required pace.
Business Challenges
The client faced multiple challenges that needed innovative solutions
Long Release Cycles
Manual deployments taking 2-3 days with frequent failures and rollbacks
Complex interdependencies between microservices causing deployment bottlenecks
Approval processes requiring multiple handoffs between teams
Inconsistent Environments
Development, staging, and production environment discrepancies leading to "works on my machine" issues
Manual configuration management resulting in drift between environments
Lack of infrastructure as code causing unpredictable deployments
Quality and Security Concerns
Limited automated testing resulting in production bugs and customer impacts
Security scanning performed late in the development lifecycle
Compliance documentation requiring manual updates after each release
Our Solution
VegaStack developed a comprehensive DevOps transformation strategy that addressed the core challenges through automated pipelines, infrastructure as code, and a cultural shift to DevSecOps practices.
Assessment & Strategy
We began with a thorough evaluation of the existing deployment processes, infrastructure, and team workflows to identify specific bottlenecks and opportunities for improvement.
Process Mapping & Analysis
Conducted 20+ stakeholder interviews across development, operations, and security teams
Created detailed workflow diagrams identifying bottlenecks and manual touchpoints
Established baseline metrics for deployment frequency, lead time, and failure rates
Technology Stack Evaluation
Assessed current CI/CD tools and infrastructure compatibility
Benchmarked existing deployment processes against industry best practices
Identified integration points for security and compliance tooling
Roadmap Development
Created phased implementation plan with clear milestones and success metrics
Designed GitOps-based workflow architecture leveraging Kubernetes
Established team training and enablement strategy to support the transition

Key Takeaways
The most important insights from this engagement
Automation is transformative
Replacing manual processes with automated pipelines dramatically reduced deployment times and human error
IaC is essential
Version-controlled infrastructure eliminated environment inconsistencies and improved reliability
Shift-left security works
Integrating security scanning early in the development process prevented costly late-stage issues
Cultural change matters
Technology alone isn't enough—team enablement and process changes were critical to success
Conclusion
This FinTech transformation demonstrates how modernizing software delivery processes can have a profound impact on business outcomes. By implementing automated CI/CD pipelines, infrastructure as code, and DevSecOps practices, the client achieved deployment times measured in minutes rather than days while significantly improving quality and security.
The new capabilities have enabled the client to respond more quickly to market opportunities and customer needs, positioning them for continued growth and innovation in a highly competitive industry. Most importantly, the cultural shift toward DevOps practices has created a foundation for ongoing improvement and scalability.
