// HELLO, WORLD.

Engineering reliable systems, defending networks, and exploring practical AI.

I am a systems and security operations practitioner based in Tangerang, Indonesia. Over the past 24+ years, I have lived through the evolution of enterprise IT — from crimping CAT5 cables, assembling hardware, and configuring Linux server fleets in 2002, to triaging 500+ daily SOC alerts in Wazuh SIEM and evaluating LLM prompt stability today.

[01 // CASE STUDIES]
SCOPS Platform Interface
LIVE PRODUCTION Security Operations & Automation

SCOPS — Security Operations Automation Platform

Wazuh SIEM Automated Telemetry Ingestion & Incident Triage Gateway

In active SOC environments, analysts frequently suffer from alert fatigue when reviewing hundreds of raw logs daily. SCOPS acts as an automated triage gateway that connects to Wazuh SIEM managers via REST APIs, evaluates risk scores, and routes incidents into High/Medium/Low priority queues with automated NIST SP 800-61 response playbooks.

Architecture Pipeline: Wazuh Telemetry Stream → REST API Ingest → Python Risk Engine → Priority Triage Queue → SOP Incident Playbook
Python Streamlit Wazuh SIEM API NIST SP 800-61 Docker
PromptMatrix 2.0 Platform
LIVE PRODUCTION Applied AI / LLM Benchmarking

PromptMatrix 2.0 — LLM Prompt Stability Suite

Client-Side Prompt Evaluation, Drift Testing & Strict JSON Validation

LLM applications often fail silently when subtle prompt variations cause schema violations or answer drift. PromptMatrix 2.0 systematically evaluates combinatorial prompt matrices across model variants, scoring outputs on schema adherence with zero server-side secret retention (BYOK).

Architecture Pipeline: Prompt Matrix Input → Systematic Variant Generator → Multi-Model Execution (Gemini API) → JSON Schema Validator
TypeScript Next.js LangChain Gemini API JSON Schema
SmartExpenseML Interface
LIVE PRODUCTION Edge NLP / Privacy Engineering

SmartExpenseML — In-Browser Expense NLP

Sub-5ms Colloquial Indonesian Currency Normalizer & Text Classifier

Financial transaction notes must remain private. SmartExpenseML executes 100% on the client device, parsing informal Indonesian amounts (e.g., "35rb", "1.5jt", "ribu") and categorizing expenses without transmitting any data to external servers.

Architecture Pipeline: Raw Text Input → Tokenizer Regex → Category Mapping Rule → LocalStorage Sync
Vanilla JavaScript Regex Tokenizer HTML5 LocalStorage

LIVE PRODUCTION SecOps / Data Pipeline

A.R.Y.A. — SOC Analytics & Threat Hunting

Heterogeneous Log Stream Normalization Layer

Consolidates disparate log streams (JSON, XML, CSV) across network endpoints into unified threat hunting dashboards, reducing manual log inspection time by 30%.

Architecture Pipeline: Log Sources (JSON/XML/CSV) → Normalization Layer → Pandas Aggregator → Streamlit Dashboard
