01
Database operations
SQL-heavy systems, reporting, troubleshooting, access discipline, restore awareness, and database responsibilities that stay manageable after go-live.
Database / AI Infrastructure / Backend / Automation
Built for real operations, not for noise.
Database Administrator, Backend Engineer, and AI Infrastructure builder. I design zero-trust API gateways, connect LLMs to corporate databases, and build automation that keeps operations calm and scalable.
Experience
8+ years in IT since 2018. Built from hands-on delivery into database, backend, infrastructure, and operational ownership.
Scale
Exposure to 100+ servers and 400+ databases. Comfortable with repeated operational responsibility, not only one-time project work.
Focus
Production-aware systems with tighter exposure. Strong across SQL, Linux, APIs, VPC, monitoring, Fortinet context, and internal automation.
PasPapan: All-in-One HRIS & Operations
Comprehensive HRIS system featuring Face ID & GPS attendance, one-click payroll calculation, KPI appraisal, shift planning, and full CRM/Accounting integration. Built with native iOS & Android support and a multi-branch admin dashboard.

What I actually do.
The work is centered on useful technical ownership: data, services, infrastructure, access boundaries, and operational clarity.
02
Backend and API work
Services, read-only API layers, auth-aware flows, gateway thinking, and backend structures that respect operational constraints.
03
Infrastructure and network
Linux, systemd, VPS/cloud, VPC, service exposure control, reverse proxy design, monitoring visibility, and Fortinet-related context.
04
Analytics and automation
ClickHouse direction, pipelines, crawlers, dashboards, and practical AI-assisted automation for reducing repetitive technical work.
Stack
Core stack.
Kept direct, because the stack is only useful when it supports real delivery and cleaner operations.

How it evolved.
Started from practical software delivery, then moved deeper into database-heavy work, backend systems, infrastructure ownership, and platform-minded automation.
2018
Entered professional IT work. Began from direct delivery, including early Android/mobile experience, before moving closer to backend and database operations.
2019–2024
Expanded into DBA, backend, and infra depth. Worked with reporting, SQL-intensive operations, Linux environments, internal systems, and recurring production responsibilities.
2025–Now
Pushing toward platform and automation direction. More focus on gateways, ClickHouse-oriented analytics, monitoring visibility, and AI-assisted workflows.
Work
Selected directions.
Work that improves operational usefulness: clearer data exposure, stronger visibility, better service boundaries, and less needless complexity.
Data platform
CH OLAP Pipeline Multi-database CDC and analytics direction into ClickHouse for DBA, infra, and data-platform engineering needs.
Open
API gateway
Dynamic Data API Gateway Read-only data API management with cleaner routing, auth awareness, and stronger operational boundaries.
GitHub
Ops automation
Daily Work Automation Scripts, crawlers, monitoring flows, and AI-assisted automations that reduce repetitive work and speed up technical response.
