What We Did
• Diagnosed and resolved AKS private cluster networking issues including private DNS zone configuration
• Fixed DNS resolution between AKS pods, Azure services, and on-premise resources
• Restored and optimized Azure Virtual Desktop (AVD) accessibility for the development team
• Implemented proper network security groups and private endpoint configurations
• Set up monitoring to prevent recurrence of connectivity issues
Results
✓ Private cluster communication fully restored with zero downtime
✓ AVD accessibility issues resolved — development team productivity restored
✓ Proper DNS architecture in place preventing future resolution failures
✓ Reduced networking-related incidents by 90%

Claribel — Cloud Migration & Cost Optimization
Industry: Technology
The Challenge
Claribel was running their infrastructure on DigitalOcean and needed to migrate to Microsoft Azure for better enterprise features, compliance capabilities, and scalability. They also needed to optimize their cloud spending.

What We Did
• Implemented encrypted communication between services using AWS KMS for key management
• Conducted comprehensive risk assessment across the entire AWS infrastructure
• Performed SAST (Static Application Security Testing) across all application codebases
• Deployed Sentry for application performance monitoring (APM) and error tracking
• Established security baselines and ongoing vulnerability management processes
Results
✓ All inter-service communication encrypted with AWS KMS-managed keys
✓ Complete risk assessment report with prioritized remediation roadmap
✓ Critical code vulnerabilities identified and remediated through SAST
✓ Real-time application monitoring with Sentry reducing MTTR by 50%
