About

Mostly AI applications and the infrastructure underneath them. I care about architecture, latency, and what a system does on a bad day — not about what it does in a demo.

I measure before I argue, and I publish what the instrumentation said, including when it disagreed with me.

Infrastructure  →  Systems  →  AI  →  Production Engineering
  • AI application architecture — retrieval, agent loops, and the plumbing around them
  • Performance & latency engineering — profile first, then change one thing
  • Production systems & reliability — failure modes, back-pressure, safe defaults
  • Agentic systems & automation — task queues, verification gates, auditable state
  • Infrastructure & systems engineering — storage, distributed services, CLIs
  • Full-stack when the product needs it

Currently running: OpenClaw — a voice-only assistant split across a Raspberry Pi and a Mac: local speech-to-text and text-to-speech, an indexed notes vault it can answer from, and an unattended automation lane that submits its work through Bridge's queue instead of touching the repositories directly.

Selected work

Project What it is
Nuvia Platform Planned nutrition logistics platform connecting dietitians, suppliers, couriers and customers. Architecture and product system, currently in pre-pilot validation.
Bridge Rust Coordination layer for attended and unattended agent work: SQLite task queue, atomic claims, token caps, git worktrees, verification gates with no force flag, append-only trace.
Project Syncopated Silicon Python Automated media-generation pipeline — LLM prompt expansion, track and image generation, compositing, scheduling, multi-platform publishing.
Chain Storage TypeScript · Go Blockchain-backed distributed file storage: React dApp over on-chain storage allowance, IPFS upload services, output router.
Local IPFS Server TypeScript Service that turns a database collection into an IPFS pinning queue — local daemon and gateway pinning, gateway links written back.

Writing

I write about engineering through measurement rather than hype — AI systems, performance, infrastructure, and the assumptions hidden inside products.
