DevSecOps & Cloud Architecture
Deterministic, repeatable, and secure cloud infrastructure. We engineer production-grade multi-cloud (AWS, Azure, GCP) and hybrid environments using modular Terraform, automated pipeline controls, and aggressive blast-radius containment.
Cloud Engineering Disciplines
We replace manual console clicks and fragile cloud sprawl with audited, automated, and cost-optimised infrastructure code.
Infrastructure as Code
Modular, testable Terraform architecture with remote encrypted state locking (S3/GCS/DynamoDB), strict module tagging, and continuous drift detection.
- • Zero click-ops policy enforcement
- • Environment parity (Dev, Staging, Prod)
- • Automated tfsec & checkov linting in CI
Cloud Well-Architected & IAM
Strict separation of concerns using Cloud Organization hierarchies, Service Control Policies (SCPs), short-lived credentials, and least-privilege permission boundaries.
- • Multi-account and multi-tenant topology design
- • Non-root runtime policies
- • KMS envelope encryption at rest
CI/CD & Supply Chain Security
Locking down GitHub Actions and deployment pipelines with OpenID Connect (OIDC) authentication, eliminating static cloud access keys, and scanning dependencies.
- • OIDC token-based cloud deployment
- • Secret scanning & pre-commit hooks
- • Software Bill of Materials (SBOM) generation
Container Security & Isolation
Hardening Docker and container images through multi-stage minimal builds, non-root user execution, read-only root filesystems, and vulnerability scanning.
- • Distroless container images
- • Seccomp and AppArmor profiles
- • Trivy image scanning in build runners
Cost & Architecture Optimisation
Targeted architectural refactoring to eliminate redundant NAT gateway bandwidth fees, prune orphaned snapshots, right-size compute, and adopt Savings Plans.
- • NAT Gateway & VPC Endpoint analysis
- • Tiered storage lifecycle rules
- • Spot and Graviton ARM64 migration
Network Architecture & Zero Egress
Designing private VPCs with zero public IP assignment on database tiers, transit gateway routing, and private connectivity via Cloud PrivateLink and Tailscale subnet routers.
- • Private subnet segregation
- • VPC peering vs Transit Gateway analysis
- • Flow log ingestion & analysis
