AI agent platforms · distributed systems

Agents are fast, and capable, but hard to steer, and unpredictable. Driving them to build software you can actually trust and ship is the engineering discipline I’ve mastered.

I build the layer underneath the agents: the coordination, verification, and release infrastructure that lets a fleet of them work on one codebase at the same time without stepping on each other — and lets a human trust what comes out the other end. Before that I spent twelve years building and running a fully automated commerce platform. I was building automations long before agents, and now I’m having them automate the automations.

PaperCusp

Agent platform 2026 — present

A local-first platform where fleets of AI agents plan, coordinate, implement, test, and release complex software with limited human oversight. TypeScript/Hono operator API and a React/Tauri desktop app over embedded PostgreSQL.

  • Orchestration model for agent fleets, project harnesses, plans, and work queues — collision-safe file claims, dependency-aware scheduling, event-driven wakes, and restart-safe session recovery.
  • Blueprint-driven harness system for reusable agent roles and workflows spanning software development, research, review, migration, and general knowledge work.
  • Multi-account inference gateway with rate-aware routing and failover, so concurrent agents share model capacity without hard-coding a single provider credential.
  • Self-improvement pipelines built on rubrics, scorecards, and feedback loops that turn production observations into prioritized, traceable improvements.
  • Release infrastructure spanning unit and integration tests, real Tauri desktop verification, guarded promotion, deploy health checks, and rollback — dogfooded with 50+ concurrent agents on its own codebase.

Prediction markets 2026 — present

An automated bidder for prediction markets — Polymarket and Kalshi — built as a Tauri desktop app with an embedded Postgres and a live trading engine. It is strategy-agnostic by design: the same path a backtest replays is the path that trades.

  • A real pipeline, not a script. Prospector ingests markets from the venues, an analyst produces a calibrated probability, the engine sizes the position past the risk gate, and the order manager places it — every stage inspectable, every decision auditable.
  • Analyst and trader are separated on purpose. The research side emits a calibrated probability and a rationale, and never sizes a position. The money side trades on edge = p_model − p_market, only past a threshold beyond fees and spread.
  • Risk is structural. Fractional Kelly sizing, hard exposure caps, idempotent orders, and an armed kill-switch on the top bar of every screen.
  • Paper-first, with a pre-registered gate. Real money is not armed until forward-validated evidence clears targets fixed in advance — closing-line value, Brier score, and per-stream scorecards accrued on live market data. The bars do not move to meet the results.
Built on PaperCusp

Oddsmith runs on the same agent infrastructure I built. Its research desk lives in PaperCusp as the oddsmith-ops pot: agents ingest markets from the venues, queue each liquid one as a bet-analysis task, and hand it to an analyst to price into a signal. The trading system’s own development and its daily research loop run on the same coordination, queueing, and audit layer.

Pre-registered goals

Every evaluation target is fixed before the data arrives, then scored against real forward results.

Oddsmith's go-live evidence panel: the forward-validation verdict, CLV convergence trend, and per-stream forward scorecards

“May we arm real money yet?”

One panel whose entire job is to answer that question with evidence instead of confidence.

Store Wolf

Commerce at scale 2013 — 2025

The company I founded and ran for twelve years: a fully automated commerce platform that generated over $1M per month in revenue while needing only three warehouse staff to operate. Almost none of the difficulty was in the selling — it was in keeping millions of records correct across systems that were never designed to agree with each other.

  • Distributed synchronization of inventory, pricing, orders, and listings across millions of SKUs and multiple marketplaces, with serial-level tracking and high-performance caching.
  • A fulfillment optimizer that modeled 100K+ SKUs as a weighted graph; bitmap indexing evaluated millions of configuration paths and recomputed lowest-cost fulfillment in roughly sixty seconds.
  • An LLM-assisted product matcher that combined model confidence with human-calibrated thresholds, so high-confidence marketplace matches could be automated safely and the rest escalated to a person.
  • Microservices for distributed execution and cross-machine communication, plus automated listing, advertising, price-history, and availability engines.

Restart

Demo build 2026

A demonstration build, not a business — a multi-marketplace listing platform and B2B storefront I put together to show the architecture end to end. The catalogue and the figures on it are sample data; there are no real customers or orders behind it.

  • One description in, six marketplaces out. A universal product schema is the pivot; per-marketplace adapters map it to Amazon, eBay, Walmart, Backmarket, Newegg, and Google Shopping.
  • The model sits inside the typed path, not around it. An LLM classifies the product type, then extracts properties under the matching Zod schema — validated and rejected on a miss, never quietly defaulted.
  • Vision-verified imagery. Candidate product images are checked by a multimodal model — no watermark, single product, actually matches the description — and the listing is rejected if none pass.
  • NestJS microservices over a Redis transport with Postgres and Drizzle, each marketplace subscribing to its own listing topic, plus a description cache keyed by content hash so repeat inputs skip the model entirely.

Get in touch

I’m interested in the hard version of the problem.

I’m looking for a senior or principal role where the difficulty is systems rather than scope — agent infrastructure, developer tooling, distributed systems, or anything where correctness under concurrency is the actual problem. I’m just as glad to talk with founders and investors about PaperCusp.
