Portfolio

Since 2019 (~7 years) until now, I have been involved in various projects. Information about companies and projects that I have handled can be found on this page. However, for active projects, I will censor the company name until I am truly no longer involved in the project.

Accomplishment Project

In this project, I did a lot of troubleshooting on "Known Issues" such as "one ceph osd failure impatch the whole cluster, connectivity overlay network, HA Kubernetes Failover goes fail, problem with ingress k8s, etc."
I also did deployment monitoring, rules alerting, tuning, and more.

I have been involved in this project from the beginning until now as a consultant.
In this project, I handled various unusual issues such as "NFS Hit Bugs, Server Hung," and conducted Root Cause analysis of an issue that could occur. Then I provided advice so that the issue would not occur again.

Implementation & Manage Service Openstack Iaas Cloud and Kubernetes Cluster - PT Bank ███████ Indonesia (2020 - 2022)
I have been involved in this project from the beginning of the Implementation Trial, Real Implementation, to Manage Service.
We implemented and managed more than 100 nodes, and did many things from creating deployment tools with Ansible to deploying CEPH, monitoring, alerting, centralizing logs, and K8s. When we entered the Manage Service phase, I did a lot of troubleshooting on issues such as network overlay, hardcode software, tuning, and more.

In this project, I managed the Openstack cluster, did troubleshooting, deployed monitoring, troubleshooted VMs, and more.
In some cases, I did troubleshooting on all in-scope projects.

Manage Service Openstack Iaas Cloud and ELK Stacks - ID████████ Service Solution (2020 - 2022)
In this project, I ensured that the VMs and ELK stack were running properly. Additionally, I made sure that monitoring and alerting were running normally.

Manage Service Openstack Iaas Cloud and Roles as DevOps Engineer - PT Sakti Kinerja Kolaborasindo (2019 - 2020)
This job was the starting point for me to get involved in the IT world. Here, I deployed Openstack & CEPH Cluster from mounting server to Data Center until the VMs were ready to be used.
It didn't stop at making the VMs ready to use, after that, I also configured the workflow CI/CD, Haproxy config, Traefik, managing K8s Cluster, etc.
