IT Systems Expert & PhD Candidate in AI
Researching efficient LLM on edge devices | ERP | Cybersecurity and private on-premise AI
I help organizations run AI on their own servers, so sensitive data stays inside the company, and I secure the infrastructure underneath it.
Based in Surabaya, working with organizations across East Java and Indonesia.
How I can help
- Private AI on your own servers
- Language models and automations, such as document search, internal assistants and ERP workflows, running on hardware you control and sized to your workload and budget.
- ERP and database systems
- ERP implementation and customization, and SQL databases set up to stay accurate and recoverable, so your daily business data is always available when you need it.
- Cybersecurity and secure networking
- Server and network hardening, secure network setup, and penetration testing with a written scope. You receive a clear report of what was found and what to fix first.
- IT and AI consulting
- Practical IT and AI advice for businesses and for research projects, from choosing an approach to reviewing a system you already have.
Experience
I work daily with Linux servers, LLM, virtualization (Proxmox, VMware, etc), containers (Docker, LXC, etc), SQL databases, ERP systems, local language models with Ollama / LM Studio and AI agents and workflow automation with n8n / OpenClaw / etc. My security work includes server and network hardening, penetration testing, and server-side implementation
My background is in electrical engineering and informatics, so I am comfortable working from the hardware up to the application.
- PhD candidate, Computer Science: AI, cloud and edge devices
- Master of Computer Science: network security and big data
- Bachelor of Electrical Engineering: robotics and microprocessors
Research
Alongside my work as an IT practitioner, I am a researcher. Some of my work is published in scientific papers. Other experiments I run for myself and never write up, but I rely on them in my daily work as an IT and AI expert.
