AI medication companion with adaptive reminders and behavior-aware tracking Health / Mobile +
Overview

A medication reminder app that adapts to how people actually behave, not just how they are supposed to. Combines reminder logic, OCR-based medicine input, voice logging, and supply tracking into one mobile system.

Key Features
  • Scans medicine packaging and converts it into structured input
  • Learns real intake patterns and adjusts reminder timing
  • Supports natural voice-based dose logging
  • Predicts refill timing based on usage
  • Uses interactive reminders instead of passive alerts

Predict My Life

Multi-agent simulation engine for decisions, futures, and branching outcomes Simulation / AI +
Overview

A scenario simulation product that models multiple possible life paths through parallel agents. Built to explore consequences, decision trees, and compounded outcomes with more clarity than ordinary reflection tools.

Architecture Highlights
  • Agents share memory through a persistent graph-based layer
  • Branching paths visualized in timelines and probability flows
  • Claude drives structured simulation reasoning
  • Local Docker deployment supports privacy-sensitive use

Terra Data

Data classification and compliance system for Indonesian regulatory context Govtech / Compliance +
Overview

A governance and compliance platform built around Indonesia's UU PDP framework. Designed for environments that need auditability, role-based access, and data sovereignty through on-prem deployment.

Core Capabilities
  • Classifies data assets against regulatory categories
  • Immutable audit logging through hash-chain structure
  • Supports on-prem deployment requirements
  • Separates permissions across admin, compliance, and viewer roles
  • Built for high-throughput processing with async architecture

The Boards

AI advisory system for structured debate and business decision-making Strategy / Marketing +
Overview

A multi-agent decision environment where different AI roles argue, challenge assumptions, and log reasoning across sessions. Built to turn vague business thinking into clearer strategic choices.

System Design
  • Multiple agents take distinct positions in debate
  • Model routing balances depth and cost
  • Decisions and arguments are recorded in audit logs
  • Learning loops improve future sessions
  • Interface is intentionally focused and minimal

Jinx

Three-layer AI mirror for psychological insight and pattern recognition Psychology / Mirror +
Overview

A conversational AI system designed to analyze internal patterns, generate reflective responses through distinct personas, and score output quality before presenting it back to the user.

Pipeline
  • Analyst extracts emotional and psychological structure
  • Mirror generates the user-facing response in persona voice
  • Critic evaluates quality and triggers rewrite when needed
  • User state compounds over time into an evolving model
  • RAG supports depth through psychology and systems-oriented source material

Designing
things
that think.

I come from UI/UX design, but my work has expanded into product systems, workflow logic, and AI-powered tools. I design around how a system should think, behave, and support decisions — then use modern tools to help bring it into working form.

I'm especially interested in products where interface alone is not enough: operational systems, intelligent workflows, decision environments, compliance tools, and behavioral products. My role is to bridge product vision, logic, and execution.
