Current Profile
An online, up-to-date summary of the engineering work represented across this site.
I build applied AI products and backend systems with the infrastructure, security, and human workflows around them in
view. My work spans voice agents, structured evaluation, APIs, data systems, Linux operations, smartcards, and IoT. Across
those domains, I focus on clear architecture, maintainable implementation, observable behavior, and operational readiness.
Core Capabilities
Applied AI
- Voice interview workflows
- Gemini/Vertex AI integration
- Structured scoring and evidence
- Human-in-the-loop review
Backend & Data
- Python and TypeScript services
- API and data contracts
- State machines and realtime workflows
- PostgreSQL and BigQuery patterns
Platform & Operations
- Linux, systemd, and Nginx
- Ansible and Podman
- VPS and Cloud Run workflows
- Health checks, runbooks, and recovery
Security & Connected Systems
- eMRTD/BAC and secure messaging
- Java Card workflows
- IoT telemetry pipelines
- Deployment hardening
Selected Evidence
- Built AIN Hire, a Bahasa Indonesia voice-screening prototype with bounded interviews, separate scoring, audit evidence, and human sign-off.
- Built and tested a Java-based ePassport emulator covering ICAO 9303 personalization, BAC/secure messaging, passive authentication, and physical-card workflows.
- Created a repeatable RHEL-style operations lab using Ansible, Podman, systemd, firewalld, SELinux-aware troubleshooting, and operational reporting.
- Shipped an IoT monitoring backend that turns sensor telemetry into real-time dashboards, history, alerts, acknowledgements, and operator workflows.
