• Ship and run a daily AI news briefing alone, from product to on-call: unattended since January 2026, with its cost and every failure public (Projects)
• Building Dispatch, an agent platform where nothing reaches a regulated client on the model's word alone; rehearsed end to end, not yet in production
• Shipped Steer alone, from Swift code to website: a native macOS app that turns a game controller into full desktop input

• Got a CI pipeline that had been red for years green again, so the team could deploy instead of shipping around it
• Set the frontend modernisation strategy and pitched it to the client's stakeholders, who expanded the engagement to a design-system overhaul
• Unblocked modularisation of a Rails 3.2 codebase with no fork left to maintain, and deleted 715k lines; my training on it earned CTO and founder recognition

Fast-growing community SaaS: 600+ communities in 4 regions, the largest serving 1M+ users.

• Doubled deploys (2 to 4 a week) and halved build times (15-20 to 7-10 min) for 40 engineers, with a CI pipeline generator that skipped unneeded suites
• Cut the CI bill €160k a year (8-11% of the infrastructure budget) by migrating from Semaphore to Buildkite
• Cut data exports 98% (24h to 15-45 min) for 1M+ user communities, clearing hundreds of support tickets and the churn risk behind them
• Cut onboarding from 2+ days to about an hour through automated setup, returning roughly 80 developer days a year
• Made the case for and led the Ruby 3 and Rails 7 upgrade across 40 developers: zero downtime, no feature freeze
• Worked directly with the CTO on architecture; designed 5-tier on-call escalation and the interview process; supported team growth from ~15 to 40 developers

A newsroom that runs itself: three dozen feeds from about 30 outlets, 500+ articles a day, and no human edits any issue. The model never sees a URL, so nothing it writes can smuggle a link in, and an LLM-as-judge gate re-checks every headline against its sources before send. Unattended since January 2026, a few dollars a run, with cost, source health and every failure public on a live stats page.

Fixes where Ruby systems fail under streaming and fibers: fiber-safe hub storage shipped in Sentry's Ruby SDK 6.7.0, plus merged fixes in NextDNS's Go resolver, Rack and RuboCop.

Back-office workflows for regulated businesses, run under a human gate. Autonomy bands decide what waits for a signature, and code fills every figure and deadline, so a letter cannot invent a number. Temporal owns every lifecycle; Postgres row-level security isolates each tenant. Rehearsed end to end; not yet in production.
