DevOps and cloud engineer focused on AWS architecture, CI/CD automation, Kubernetes, release governance, and production-oriented infrastructure.

I work on systems that connect infrastructure design with delivery workflows: environment strategy, artifact promotion, deployment automation, observability, cost awareness, and operational reliability.

Current focus areas include AWS ECS/Fargate, Kubernetes, Terraform, GitHub Actions, Jenkins, GitOps, monitoring stacks, and secure multi-environment delivery.

• Designed AWS architecture for a conference platform using ECS Fargate, Aurora PostgreSQL, Redis, CloudFront/WAF, ALB, ECR, S3, CloudWatch, and external secrets management.
• Produced ADRs for compute, networking, database, CI/CD, artifact promotion, backups, monitoring, and cost-control decisions.
• Built CI/CD and release workflows using GitHub Actions, Jenkins, Docker, AWS ECR, SemVer, and GitOps-based promotion.
• Built and operated a production educational platform with backend, web/mobile client, deployment automation, health checks, rollback scripts, and test gates.
• Delivered a business workflow automation dashboard for a client managing significant outstanding collections exposure, improving follow-up visibility and operational control.

Designed a cloud architecture for a conference platform including frontend delivery, backend services, managed database, Redis, CI/CD, monitoring, secrets management, and environment strategy.

Key areas:

• ECS Fargate service architecture
• Production, Simulation, and ephemeral Test environments
• Aurora PostgreSQL and Redis design considerations
• CloudFront/WAF, ALB, ECR, S3, CloudWatch
• Build-once / promote deployment model
• ADRs and FinOps cost evaluation

Built and operated an educational platform with backend, web/mobile client, deployment automation, health checks, rollback scripts, and release workflows.

Key areas:

• FastAPI backend and Expo web/mobile client
• GitHub Actions pipelines
• Docker and AWS ECR
• Pull-based production deployment on EC2
• Docker Compose, systemd timers, health checks, and rollback scripts
• Backend tests, API contract tests, authorization checks, client tests, and mobile E2E suites

Built an operations dashboard for a client managing project workflows and outstanding collections exposure.

Key areas:

• Project-state modeling
• Reminder and follow-up logic
• Collection event tracking
• Attention dashboards
• Business metric redesign
• Workflow bottleneck analysis

Hands-on infrastructure and delivery projects covering Jenkins, GitHub Actions, Docker, Kubernetes, Helm, Terraform, Artifactory, GitOps, and observability.

Examples:

• Multi-repository Jenkins release orchestration
• Ephemeral environment automation
• Kubernetes GitOps deployments with Helm
• NGINX Ingress, RBAC, cert-manager, and network policies
• Prometheus, Grafana, Alertmanager, Fluent Bit, Elasticsearch, and Kibana

• CI/CD that is understandable, repeatable, and controlled
• Infrastructure decisions backed by operational and cost trade-offs
• Secure deployment workflows without long-lived cloud credentials
• Clean environment separation without unnecessary platform complexity
• Observability that helps debug real incidents, not just display dashboards
• Release processes that support rollback, promotion, and ownership
