The Client

Schuman Financial

Schuman Financial is a euro stablecoin issuer, infrastructure, and payment company. With an EMI license in France, Schuman provides a stablecoin technology platform and institutional-grade infrastructure that includes full API automation, instant 24/7 conversion between stablecoins and euros, named IBANs, 24/7 on-chain FX, and free, instant payments worldwide.

Schuman approached Plectrum on a recommendation while preparing to launch a new cross-border payments platform – the product vision was moving forward, but the infrastructure underneath needed a rebuild.

The Challenge

Fragile by Default

01

Partial IaC

Infrastructure as code covered less than half of the platform’s actual footprint.

02

Single Point of Failure

Workloads were effectively relying on a single, non-autoscaled EC2 instance.

03

Incomplete CI/CD

Pipelines were incomplete and still dependent on manual steps.

04

Stale Images

Container delivery relied on the latest tag, creating stale image and caching issues.

The Delivery

0

In Detail

01

Production First

Started with production to get the client onto a secure, scalable footing within the launch window, then rolled the same blueprint into development.

02

Well-Architected by Design

Built in line with the AWS Well-Architected Framework, with a focus on security, reliability, and operational excellence for a regulated fintech.

03

Remove Risk, Not Add Complexity

Replaced fragile infrastructure with a foundation the client could actually build on, operate, and grow with.

Infrastructure & Environments

  • Multi-account AWS architecture using AWS Organizations and environment separation
  • Production and development built from the same repeatable Terraform blueprint
  • >20 AWS accounts structured under a secure multi-account model

Application Platform

  • Migration from a fragile single-instance setup to Amazon ECS on Fargate for all services
  • >15 services moved to ECS on Fargate
  • Immutable image versioning via AWS ECR, replacing latest tags with traceable artifacts

Network & Edge Security

  • Application Load Balancers with proper ACM-managed certificates
  • AWS WAF protection across public endpoints
  • >10 public endpoints protected

Data & Secrets

  • Managed PostgreSQL on Amazon RDS
  • Centralized configuration and secrets via AWS Secrets Manager and Parameter Store
  • >10 repositories standardized, including 2 newly created Terraform repositories

Delivery & Observability

  • GitHub Actions CI/CD using OIDC instead of long-lived cloud credentials
  • CloudWatch-based logging, monitoring, and alerting
  • Security guardrails for day-to-day operations and visibility

Handover

  • Detailed documentation of the solution, infrastructure code, and Terraform modules
  • Engineering-wide handover as part of the engagement
  • A clear operating model the internal team could work with after handover

The Outcome

From a Single Instance to a Production-Ready Payments Foundation

Within 5 weeks, Schuman Financial had a AWS environment built from scratch, followed by a development environment based on the same design. The single-instance bottleneck was removed, and the platform gained a much stronger baseline for scalability, resilience, and security.

Speed

Build and deployment dropped from mostly manual to a 3-minute average per environment.

Audit

GitHub Actions CI/CD runs on OIDC instead of long-lived credentials, with ECR giving every deployment a traceable, immutable image.

Focus

Developers handle more day-to-day configuration safely, so the product team can focus on shipping.

Trust

A foundation designed around the AWS Well-Architected Framework, built for a regulated EMI.
