Twenty years of shipping — a production compiler at Fog Creek, a
three-continent 80-server network at Cheezburger, marketplace platforms at Updater and TaskRabbit.
Since February 2026 I have operated in a different gear: I design and run dark
factories — multi-agent AI orchestration frameworks of my own construction that turn
rigorous specifications into tested, production-grade software while I sleep.
The output is held to a bar most human teams don't attempt: 100% enforced test coverage, formal
invariants, generated-from-code API contracts, spec-first development under a written engineering
constitution. The receipts are in git, and this resume is built so that both humans and AI reviewing
agents can check every number.

How I work
Dark factory orchestration
I run two competing multi-agent frameworks I built and benchmark against each
other — with a three-tier test harness, per-agent-role evals, ground-truth scored benchmark
fixtures, and pre-registered A/B experiments with per-dispatch token telemetry. Daily driver
since February 2026 (first on Augment Code, rebuilt on Claude Code that April).
Spec-driven development
Specification, plan, and task decomposition before a line of code — so agents (and humans) can
implement unattended and be gated mechanically. 31 features shipped this way on
Sugar Maple alone; the same method I champion at TaskRabbit.
Trust through gates — at a fraction of the cost
100% coverage thresholds, property-based tests, formal invariants, constitutions enforced by
hooks — gates that don't care which model wrote the line. So the bulk of implementation runs
on Haiku- and Sonnet-class models (97% of Sugar Maple's 739 model trailers;
the frontier tier is reserved for judgment), outrunning big-agents-for-everything on both
speed and spend.
Experience
Sugar Maple · Sugar Maple Labs, Inc.2026 – present
Founder & sole engineer nights & weekends, building
toward first revenue
Conceived and built a multi-tenant collaborative documentation platform where AI agents
are first-class editors — an MCP server surface alongside the human web UI, with
agent commits attributed via co-author trailers.
~108K lines across 10 services/apps and 8 shared packages: TypeScript (Fastify, React) services,
a Go gRPC git-storage engine, Kafka event choreography, Cloudflare Workers
edge auth, WorkOS SSO, Postgres, and cdk8s/Tilt Kubernetes — plus OpenTofu IaC promoting through
five environments with plan and apply test suites.
Shipped in roughly eight weeks by orchestrating AI agents through 31 spec-driven features under
a 22-principle engineering constitution; 98% of merged commits carry AI co-author trailers
(~16 agent commits per squash-merged PR).
Quality bar: 100% test-coverage thresholds on every package, OpenAPI contracts generated from
code, migrations only via schema tooling, in-cluster E2E suites.
Live proof-of-concept deployment on single-node Kubernetes behind Cloudflare tunnels (zero
inbound ports); production AWS/EKS path designed and costed; billing planned post-MVP.
Re-architected the platform-modernization program: authored the technical plan that unblocked
roadmap features stalled for years, and laid the technical foundation and roadmap for fully
integrating the TaskRabbit and Dolly businesses.
For the past several months, daily technical coach and guide to the platform and partnership
teams building the new partner platform: 100% backward compatible with both
the legacy TaskRabbit API and the Dolly partner API, plus a new, clean unified partner API that
books both TaskRabbit in-home services and Dolly delivery — all on a Kafka-driven
architecture.
Continual advocate for spec-driven AI development across engineering — the
path to AI-written code that scales and can be trusted.
Senior Staff Engineer, Dolly division Aug 2024 – Sep
2025
Shipped multi-courier booking — jobs that book more than one courier — on Dolly's 10-service,
fully Kafka-driven microservice platform.
Shipped order batching: bundling orders into a batch or route that becomes a single job.
Built a new support-ops tool that dramatically improved the efficiency and usability of daily
support operations.
Since March 2026, that platform has accepted only AI-authored, spec-driven
commits — a working demonstration of the method at a real company.

Led two division-wide migrations to Auth0/passwordless authentication — coordinating multiple
engineering, product, DevOps, IT, and security teams (40+ people), with real-time automatic
user migration, PCI compliance, and customer-facing SSO.
Designed and coordinated the decoupling of six tightly-bound microservices, improving
reliability and setting the division's event-driven patterns.
Designed offline-first Android architecture so effective the client cited it as the model for
the iOS app.
Nine years as a solo consultant and team lead across healthcare, finance, and education —
typically working directly with non-technical founders, owning everything from requirements to
deployment to maintenance.
Built the first versions of Rover's iOS and Android apps, then trained Rover's
own mobile team until they could take over.
Shipped mobile games in Unity, real-time analytics, lead-management and data-sync systems.
Built and ran a network of 80+ servers in 11 locations on 3 continents, fault-tolerant through
simultaneous data-center outages, for one of the era's largest humor publishers.
Managed a fully remote, highly distributed engineering team; built a culture of autonomy for
senior engineers and mentorship for everyone.
Built single-step continuous deployment — automated tests plus network-wide deploys, many times
a day, in 2011.
Lead Software Engineer 2008 – 2011
Built the content pipeline, database schema management, unified configuration, monitoring, and
an email system sending hundreds of thousands of messages a day; co-owned all infrastructure
and operations.

Fog Creek Software2005 – 2008
Member of Technical Staff
Owned the compiler for Wasabi, Fog Creek's in-house language — building
back-ends targeting the CLR, ASP, PHP, Python, and JavaScript so one codebase shipped
everywhere.
Built FogBugz's fast intelligent search and the automated testing system that verified four
builds a day.
Fog Creek is the company that later created Trello and co-founded Stack Overflow.
