Product architect · Infrastructure builder · Systems integrator

I build useful tools forfragmented systems.

My work spans product architecture, enterprise I.T., software, and self-hosted infrastructure—usually where machines, data, and workflows no longer fit together cleanly.

The projects here differ in purpose but share an approach: connect the pieces, make the boundaries clear, and build for real use.

Building useful systems

The recurring pattern

Different domains. The same systems instinct.

The work usually begins with a messy real-world system: disconnected tools, scattered hardware, fragmented data, or an operational process that should be simpler.

I connect and normalize the pieces, make policy and diagnostics explicit, and build one surface that can be understood and operated.

The body of work

Five projects, one practical throughline.

Collectibles, private AI, fleet operations, security, and health data are different problems. Each project makes a complicated system easier to see, trust, and run.

Selected systems

Built to be operated, not just demonstrated.

Each project starts with a real constraint: a fleet that needs control, a security stack that needs clarity, or data that needs a reliable model.

ProductionPrivate

Primary commercial product

TradeBroker

Collectibles intelligence, portfolio, trading, inventory, and marketplace infrastructure.

A connected product suite for collectors, stores, and market participants—built around real market data and the operational work that happens after a price lookup.

Private AI infrastructure

TensorBreeze

Every GPU you own. One private AI endpoint.

A self-hosted GPU control plane for heterogeneous Windows and Linux machines, with bounded workload routing, fleet telemetry, reservations, and topology-aware orchestration.

  • TypeScript
  • Python
  • Linux
  • Windows / WSL2
  • OpenAI-compatible APIs
ActiveOpen source

Fleet operations

AutoRMM

Self-hosted monitoring and remote access for mixed Windows and Linux fleets.

A lightweight RMM built as three dependency-free Go binaries: an always-on hub, outbound agents, and a client for monitoring and short-lived remote sessions.

  • Go
  • WebSocket
  • Linux
  • Windows

Security visibility

SecWatch

Practical self-hosted security monitoring without a giant enterprise stack.

One readable tool for edge detection, auto-ban, host visibility, CVE awareness, file integrity, and optional local-model traffic analysis.

  • Python
  • SQLite
  • Traefik / nginx / Caddy
  • CVE intelligence

Private health intelligence

GlucoPilot

Fragmented personal health data becomes one coherent analytical system.

A self-hosted, single-user platform that unifies Type 1 diabetes data, wearables, labs, symptoms, and treatment history—then makes the evidence explorable.

  • FastAPI
  • React
  • SQLite
  • Docker
  • Local AI

Open-source philosophy

Built for real use. Shared when reusable.

The public projects began as answers to infrastructure, security, data, or reliability problems—not as portfolio demos.
