Stratus Partners Limited Run the CRRI™ Assessment
Track Record

Projects our team
has delivered.

Engagements across banking, fintech, payments and ML infrastructure. Our engineers have operated inside some of the world's most demanding production environments — and the results show it.

What makes us different
  • Tier-1 production experience
    Not proof-of-concept work. Our engineers have shipped into live banking and fintech production environments handling millions of daily transactions.
  • Zero-downtime delivery
    Every migration and re-platform listed here was completed without service interruption. Uptime is non-negotiable in the environments we serve.
  • Regulated under the same rules
    PCI DSS, SOC 2, ISO 27001, FCA oversight. We have operated inside the compliance frameworks your auditors expect.
  • Senior engineers, not consultants
    The people who built these platforms are the same people who will build yours. No bait-and-switch. No offshore augmentation.

Sectors we have operated in

Built for the most regulated industries on earth.

Retail banking, investment banking, fintech payments, lottery operations and cloud infrastructure — our team has shipped production systems in environments where failure is measured in millions, not percentages. That experience is what we bring to every new engagement.

Kubernetes · EKS · Auto-Scaling · DevOps · GitOps

Self-healing EKS platform eliminating on-call incidents across peak pension processing loads

Our engineers designed and shipped a fully automated EKS platform with self-healing nodes, Horizontal Pod Autoscaling, and zero-touch failover. On-call incident volume dropped to zero. The platform now runs unattended through the peaks that previously required weekend standby rotas.

Data Platform · High-Throughput APIs · Infrastructure

Executive data platform serving petabyte-scale datasets across 500M+ accounts

We engineered high-throughput APIs capable of sub-second response times at petabyte scale against PayPal's full 500M+ user account base — a problem that had previously required pre-aggregation and overnight batch jobs.

AWS · SageMaker · EMR Studio · ML Infrastructure · Terraform

Enterprise AI/ML platform cutting environment provisioning from days to hours

We built a Terraform-based SageMaker and EMR Studio platform with standardised pipelines across Lambda, API Gateway, and CloudFront — turning a multi-day environment setup into an hours-long automated process that data scientists could run themselves.
