Platform engineering
Composable infra blueprints
Create reusable Terraform & Kubernetes stacks, hardened AMIs, and policy guardrails so teams self-serve safely.
Capabilities
Everything between local dev and compliant production.
I build paved roads that make secure, high-availability delivery the default for product teams.
Delivery
CI/CD with guardrails
Design pipelines with automated testing, secrets hygiene, deployment strategies, and intraday rollback options.
Security
Cloud security posture
Embed policy-as-code, identity boundaries, and runtime controls to keep auditors and customers confident.
Observability
Signals over noise
Wire metrics, logs, traces, and SLO dashboards that shorten MTTR and show exactly where performance regresses.
Toolchain
Operators that ship should own their stack.
Here is the tooling I lean on to go from idea to instrumentation.
Cloud & compute
AWS, GCP, OpenStack, KVM, Kubernetes, Docker, Nomad, F5 BIG-IP
Automation & CI/CD
Terraform, Ansible, Helm, Jenkins, CircleCI, GitHub Actions, Bash, Python
Observability & reliability
Grafana, Prometheus, Loki, Kibana, Nagios XI, Elastic APM, Netdata, Sentry
Data & messaging
PostgreSQL, MySQL, Oracle, Redis, Kafka, Vault, Consul
Experience & impact
Helping teams deliver confidently.
DevOps Engineer
- Used GitLab CI + ArgoCD on Amazon EKS to automate multi-environment releases end to end.
- Implemented a fluentbit-to-Elastic pipeline that kept logging costs predictable without losing searchability.
- Hardened RDS MariaDB with read replicas, RDS Proxy, and HAProxy load balancing for higher availability.
DevOps Engineer
- Migrated core services from GCP to Tencent Cloud with negligible downtime.
- Built GitHub Actions pipelines plus K6 load tests to validate performance before go-live.
- Ran Kubernetes fleets across AWS, GCP, and Tencent with New Relic observability.
Site Reliability Engineer
- Ran GCP-based workloads with GitHub Actions, Kubernetes, and Terraform hardening the underlying infra.
- Cut deployment time by roughly 70% by tagging containers with commit SHAs that could be promoted between environments.
DevOps Engineer
- Maintained highly available AWS stacks with Terraform blueprints and Ansible runbooks.
- Established GitLab CI/CD so finance product launches no longer blocked operations.
- Unified Grafana, Prometheus, and OpenSearch monitoring so product and finance teams shared the same telemetry.
Senior DevOps Engineer
- Built the Disney Club loyalty infrastructure on AWS ECS for regional go-lives.
- Supported eight concurrent client stacks across AWS, GCP, and Alibaba Cloud with autoscaling and CI/CD guardrails.
- Produced cost-optimized reference architectures and documentation for every loyalty program rollout.
DevOps Engineer
- Operated loket.com (later acquired by Gojek) with Jenkins + Ansible delivery pipelines.
- Rolled out Docker and Docker Swarm playbooks that modernized client releases.
IT Ops Staff
- Monitored Mandiri e-Cash (now LinkAja) digital banking services end to end.
- Delivered incident reports and SLA evidence for 24/7 regulator-facing shifts.
Operating principles
DevOps is culture, tooling, and agreements.
The practices I reinforce whenever I join a team.
- Automate audit trails & compliance evidence
- Shift observability left with dev-owned dashboards
- Design for graceful failure & rapid rollback
- Guardrails over gatekeepers
- Treat infra & policy as code
- Continuously reduce cognitive load for on-call engineers
Education & learning
