Building practical AI systems

I build AI agents, automation tools, and runnable product prototypes for real-world workflows. My work sits at the intersection of agent orchestration, governed data access, and human-in-the-loop automation.

What I work on

  • AI agents & automation โ€” tool-using LLM systems, workflow orchestration, and operational prototypes
  • Governed data systems โ€” auditable agent access, semantic layers, access controls, and reversible actions
  • Applied ML & embodied AI โ€” reinforcement learning, behavioral cloning, and interactive agents
  • Product engineering โ€” Python and TypeScript systems that can be run, inspected, and validated

Selected public work

  • DataSteward โ€” a self-hosted reference implementation for governed, AI-agent-native data access
  • Cyber-Superego โ€” a privacy-conscious, edge-cloud productivity supervision prototype
  • Minecraft AI Companion โ€” a dual-agent Minecraft companion built with LLM orchestration
  • Minecraft Embodied AI Agent โ€” behavioral cloning and PPO experiments on Apple Silicon
  • ScholAI โ€” a research prototype for meaning-preserving text transformation and evaluation

How I build

I start with a concrete workflow, make the smallest system that can be run and checked, then improve it with clear interfaces, evaluation, auditability, and explicit safety boundaries.
