AWS Infrastructure for Fintech & Financial Services

binbash delivers AWS consulting services for financial services companies and fintechs that require scalable, secure, and high-performance infrastructure capable of supporting millions of transactions. Our engagement model follows a proven methodology built on real-world fintech deployments, delivering production-ready AWS environments in 10-12 weeks.

We design, plan, and deploy a complete AWS Landing Zone using AWS Organizations, Organizational Units, separated accounts (management, tools, dev, prod, CDE, network), Service Control Policies, and AWS IAM Identity Center. Networking is architected as a multi-account topology with AWS Transit Gateway, AWS Client VPN, AWS Network Firewall, dedicated VPCs for inbound, outbound, client VPN, and third-party connectivity, VPC Endpoints for S3, DynamoDB, and SQS, Route 53 for private and public DNS, and Cloudflare integration. Amazon EKS clusters are deployed across dev, prod, and CDE environments with Managed Nodes, Spot Instances, Cluster Autoscaler, namespace isolation, network policies, and RBAC. Kubernetes cluster components include Nginx Ingress Controller, External DNS with Route 53, Cert-Manager with Let's Encrypt, AWS Load Balancer Controller, External Secrets with AWS Secrets Manager, Pod Identities via IRSA, and per-account ECR repositories.

We harden your environment with a comprehensive security baseline including MFA enforcement, encrypted EBS volumes, disabled S3 ACLs, and strict password policies. Organization-wide AWS CloudTrail is configured with 365-day retention. AWS Config is deployed with PCI-DSS rulesets, AWS KMS with Customer Managed Keys, IAM Access Analyzer, Amazon GuardDuty, and AWS Security Hub. A Security API Gateway layer is implemented using Kong API Gateway on Amazon ECS with Fargate in the Network Account, with AWS WAF managed through Cloudflare. Cost optimization is addressed through AWS Budgets with alerts, SNS and Lambda notifications to Slack, and AWS Cost Reports.

Deliverables include a complete IaC repository with all infrastructure as code, fully deployed and functional AWS services, technical documentation, and regular sessions conducted on a weekly or biweekly cadence.

Target industries include fintech, financial services, and payment processing companies with PCI-DSS compliance requirements. Common use cases span scalable and secure infrastructure for high-volume transaction processing, digital payment platforms, cloud-native core banking, credit card processing with dedicated CDE environments, and financial infrastructure modernization on AWS.
