At Samsung R&D Institute Indonesia, I build an internal DBaaS on TiDB, designing architecture, implementing Python backends, and configuring on-premise infrastructure with Ansible and Bash. I focus on high availability, including disaster recovery processes targeting under-five-minute RPO and under-one-minute RTO.

Previously at Cermati, I owned the event tracking service handling roughly 8,000 RPS on average and peaks of 15,000 RPS. I built Java and GCP-based streaming pipelines to BigQuery, reduced daily service costs by about 20%, and delivered a database-ingestion backup pipeline that saved about $3,000 monthly.

I also built a Laravel and JavaScript document-legalization site for ITS and have a competitive programming background, including ACM-ICPC Asia Jakarta Regional finalist placements.
