Cahyanto Setya B.

DevOps / SRE Engineer who has run production infrastructure at HungryHub, a Southeast Asian restaurant OTA. I build and operate reliable, observable, cost-efficient platforms — and I have the production receipts to prove it: I cut HungryHub's cloud costs by 20% through resource optimization, designed and operated Kubernetes workloads, and rolled out centralized observability across the stack. What I do: 🏗️ Infrastructure & Orchestration • Design and operate Kubernetes workloads and deployment pipelines in production • Infrastructure as Code with Terraform — deploy and manage services reproducibly • Support database migrations across DigitalOcean and AWS 📊 Observability & Monitoring • Prometheus + Grafana dashboards and alerting • Centralized logging with Fluent Bit and Thanos for long-term retention • Elastic APM for application performance monitoring ⚙️ CI/CD & Automation • GitHub Actions, AWS CodeBuild, and AWS CodePipeline pipelines • Automated build, test, and deployment flows • Fastlane for release automation 💰 Cost & Efficiency • Reduced HungryHub cloud spend by 20% via resource optimization and infrastructure tuning • Reliable, documented systems that are easy to operate and hand over I also spent 6+ years as a Senior iOS Engineer (Swift, UIKit, SwiftUI), so I understand the full delivery lifecycle — from code to build to deploy to operate. That means I communicate naturally with mobile and backend teams, and I design infrastructure that actually fits the applications running on it. Tech I work with: • Kubernetes, Docker, Terraform, AWS, DigitalOcean • Prometheus, Grafana, Thanos, Fluent Bit, Elastic APM • GitHub Actions, AWS CodeBuild, AWS CodePipeline, Fastlane • PostgreSQL, MySQL, Redis, Kafka, OpenSearch • Linux (Ubuntu), Nginx, Caddy, systemd Why work with me: • Proven production results, not just certificates: 20% cloud cost reduction, reliable K8s platform, centralized observability • Full-lifecycle engineer — I understand what applications need operationally • Independent and low-maintenance: I build it, document it, and hand it over cleanly • Fluent English, strong written communication, reliable timezone overlap (UTC+7) I'm glad to help you ship and operate stable, cost-conscious infrastructure.
