Former AE and Agency Marketing Strategist. Serial founder across five verticals. For the past two years: entirely focused on building AI systems, GTM infrastructure, and production software. I sit at the intersection of three disciplines that are usually separate — revenue systems, AI engineering, and software development. I build tools I actually run in production, frameworks I use to do better work, and GTM infrastructure I've operated from the ground up. I take on focused engagements where I can ship fast, leave documented systems behind, and make a measurable difference in a short time.

A structured workflow engine that treats every complex task as a temporary expert organization: assembled for a single mission, run with discipline, and leaving a full audit trail. Built for Claude Code's dynamic workflow model — parallel subagents, adversarial red-teams, multi-round critique loops, and a senior synthesis layer that resolves tradeoffs before anything ships.

The framework ships with a complete Skill Spec, Engineering Spec v1, JSON schemas for all 11 artifact types (Mission Brief, Expert Map, Workflow Plan, Evidence Index, Decision Ledger, Red-Team Report, and more), and prompt templates for every phase. Designed to be installed directly into a Claude Code repo.

Execution, not advice

I build the thing, not a recommendation for the thing. Every engagement ends with working systems, not decks.

AI-native speed

Claude Code in full auto-approve mode is my primary build tool. I ship in days what most quote in weeks. Documentation quality doesn't drop — the timeline does.

Operated, not just configured

Everything I've built, I've run in production. I know the failure modes — deliverability gaps, CRM data model issues, signal routing edge cases — because I've fixed them.

Documentation-first handoff

Every system comes with documentation your team can run without me. The goal is always for me to become unnecessary.

Async-first, EU hours

Based in Cebu. Work EU business hours. Structured daily handoffs mean your team wakes up to progress, not status requests.

Focused engagements only

I work best with a defined outcome and timeframe. 3–6 months, clear deliverables, measurable output. That's the environment where I consistently over-deliver.
