My Services

Cloud Architecture

Design and implementation of scalable AWS/Azure/GCP infrastructure with best practices for security and reliability.

Infrastructure as Code

Provisioning and management of infrastructure using Terraform/Terragrunt with reusable modules and clean state strategy.

CI/CD Pipelines

Automated build, test, and deployment pipelines (GitHub Actions/GitLab CI/Jenkins) with safe rollout strategies.

Containerization

Dockerization, Kubernetes deployments, Helm charts, and cluster operations with robust deployment patterns.

Observability

Metrics, logs, tracing, and alerting (Prometheus/Grafana/ELK/CloudWatch) to reduce downtime and MTTR.

Security & Hardening

IAM least privilege, secrets management, network segmentation, and baseline hardening for production workloads.
