Building the nervous system for agentic engineering.

A connected platform that observes work, evolves its own tooling, applies that intelligence to real agents, and learns from validated outcomes.

Agentic Engine
Two engines. Everything else benefits.

Observe + evolve, then, recalibrate

Vireo observes and remembers. Darwin evolves. MAIA and Devmo turn that into real outcomes — validated in a production-shaped sandbox, with results returning to memory.

THE OBSERVABILITY CORE

Vireo

The flight recorder for AI agents

You can't trust an agent you can't see. Vireo captures everything one does — then turns it into memory the next run can use.

Vireo records what an agent actually did — across the CLI, shell hooks, MCP, and skills — and distills those logs into procedural, failure, and semantic memory the next run can draw on. It installs in two minutes and became the team's standard for watching agents in production. With Darwin, it's the engine every other system here runs on.

THE SELF-EVOLUTION CORE

Darwin

Skills that improve themselves

If a task has a prompt in, an answer out, and a way to score it, Darwin evolves it — automatically, and opens the PR.

Darwin takes the skills agents run on, tries many variations, keeps the best, and opens a pull request with the upgrade — every attempt saved with its score and reasoning, so each round builds on the last. It plugs into any repo with no fork. This is the loop that quietly improves MAIA and Devmo underneath them.

THE MERCHANT-FACING BENEFICIARY

MAIA × Venmo

Cold-start to live in 20 minutes

An ephemeral Claude-CLI agent — built entirely from skills and subagents — that onboards a new merchant end to end.

MAIA is bootstrapped and ephemeral: a Claude-CLI agent assembled from skills and subagents — the same skills Darwin evolves and Vireo observes. It's the merchant-facing payoff of the engine. Over one weekend I grew its test corpus from 332 to 9,513 real scored businesses; onboarding that took ~3 months now runs in about 20 minutes.

THE INTERNAL BENEFICIARY

Devmo

Venmo's agent — and its hive mind

MAIA faces merchants; Devmo faces the org. It turns the signals Vireo captures into organizational memory Venmo can act on.

Devmo is the internal counterpart to MAIA. It leans on the same Vireo + Darwin engine, but because it lives inside the org, it can do more: build a hive mind from the organizational insights, lessons, and signals Vireo captures — and evolve far more than skills. It reaches the whole internal surface area of how Venmo's engineers actually work.

Externalization and self-service scale-upVALIDATION

Merchant Sandbox

A production-shaped validation surface for checkout, authentication, release, and partner workflows — tested end-to-end on iOS.

  • Helped lead and personally tested merchant sandbox flows end-to-end across the iOS-majority user base.
  • Owned iOS identity, domains, entitlements, provisioning, CI, and TestFlight distribution.
  • Diagnosed authentication, universal-link, direct-API host, and switchback behavior.
AI Enablement · org-wide leverage

Claude Cosmos

A Claude-CLI harness that lets any Vertex AI model run behind one consistent agent interface — with sanitization, PII scrubbing, and telemetry baked in.

Org-wide proxy

ai-video-toolkit

Turns code and technical work into narrated explainers that keep product launches current — Remotion 4.0 + Google Veo / Chirp3-TTS, runnable from GitHub Actions.

Launch storytelling

n8n

My favorite way to teach others how automation works — and a powerful internal automation tool for the enterprise.

Automation + teaching

Nested macOS

Apple Virtualization gives agents a safe sandbox and parallelizes iOS tests for 2–3× faster runs — a secure runtime substrate for agent experimentation and the iOS test fleet.

Runtime substrate

DX Sounds

MCP server merged into the PayPal AI Hub — 8 themes, 14 tools. Sonic confetti for your dev loop.

Devmo Prompt Enhancer + Guardrails

Guardrails and prompt enhancer migrated into the canonical Devmo repo. Guardrails ship with ~90 tests including a prompt-injection battery.
