How a release moves

  1. Build

    Jenkins, GitLab CI, Git Flow

    Pipelines for every service, plus one that builds and publishes the mobile APK.

  2. Scan

    Trivy, SonarQube, OWASP Dependency-Check, OWASP ZAP

    Security and quality gates run on every build, before anything ships.

  3. Ship

    Docker, Kubernetes (EKS and on-prem), Rancher, Ansible

    Rolling updates on fault-tolerant clusters; Ansible for apps that aren’t containerized.

  4. Scale

    KEDA, node groups, Terraform, Terragrunt

    Event-driven autoscaling across 30+ workloads, with infrastructure defined as code.

  5. Observe

    ELK, Grafana, Loki, Promtail

    Centralized logs and live API health checks, so incidents are found and fixed faster.

50%

lower monthly AWS spend

Cutting a client’s AWS bill in half

A FinOps review that rightsized compute, moved steady workloads to Savings Plans, switched off idle non-production environments and cleared out forgotten resources, without hurting performance.

AWS Cost Explorer, Compute Optimizer, Savings Plans, Terraform

AWS infrastructure built with Terraform

Reusable modules for networking, EKS and EC2, so every environment is created the same way and every change is reviewed as a plan first.

Terraform, Terragrunt, AWS VPC, EKS, EC2, ALB

Secure CI/CD

One pipeline pattern for Java, Laravel, Python and JavaScript services, with image, code and dependency scanning built in as gates.

Event-driven autoscaling for 30+ workloads

Kubernetes on EKS and on-prem that scales on real demand, absorbing peak payment traffic without over-provisioning.

Central logging and live API health checks

Logs from servers and pods in one searchable place, plus uptime checks on key APIs, so the team finds causes instead of hunting for them.

Elasticsearch, Logstash, Kibana, Beats, Grafana, Loki

Kafka clusters with visual monitoring

Kafka for service-to-service messaging, with Redpanda Console giving developers a clear view of topics, consumers and lag.
