I'm Khamdan, a Senior Backend Engineer in Jakarta with 6+ years building enterprise integrations, billing systems, embedded analytics, and data platforms for Indonesia's largest organizations.
APIs, billing systems, and enterprise integrations built for scale — Python, Django, PostgreSQL, and message queues that don't drop a beat.
CI/CD pipelines, Docker deployments, monitoring, and infrastructure automation for SMEs that need enterprise reliability without the enterprise headcount.
Embedded analytics and self-hosted BI — Apache Superset deployments, dashboard embedding, and data pipelines from source to insight.
Django + nginx + PostgreSQL portal with embedded Superset dashboards, deployed on a fully offline government server.
High-volume billing and reconciliation backend for a national telco environment — accuracy at millions of records.
Embedded BI dashboards into client-facing products for FMCG and mining-sector enterprises across Indonesia.
Proxmox cluster, MikroTik split-routing, self-hosted everything — plus a computer-vision project counting oil palm fresh fruit bunches.
I take on freelance DevOps and backend projects for SMEs and agencies. First call is free — bring your messiest server.
