Work

Bring me the problem, not the job spec.

Most of my work arrives as a symptom: numbers nobody trusts, tools that don't talk, work that shouldn't be manual. I find the system underneath, then build the fix into what you already run.

01 · Where it usually starts

It begins with a sentence like one of these

Measurement

We don't trust our numbers.

The situation

GA4 says one thing, the ad platforms say another, and the board deck uses a third. Nobody trusts the dashboards, so decisions fall back to gut feel.

What gets built
  • Event schemas designed around the questions you actually need answered
  • Tracking implemented across web, product, and backend sources
  • Attribution that survives scrutiny, including before identity exists
  • Reporting tied to revenue, not vanity metrics
  • Documentation your next hire can pick up
  • Segment
  • GTM
  • Mixpanel
  • Amplitude
  • GA4
  • Looker
  • Metabase

Integration

Our tools don't talk to each other.

The situation

Every platform is fine on its own. The gaps between them are where data dies and manual work breeds. Leads fall through, lists go stale, and someone re-keys the same record twice.

What gets built
  • CRM, lifecycle, and ad platforms connected to one source of truth
  • Webhooks and syncs wired into existing workflows, not bolted alongside
  • Audience and contact data moving cleanly with monitoring
  • Closed-loop reporting back to the channels that spent the money
  • HubSpot
  • Segment
  • Customer.io
  • Klaviyo
  • Census
  • Hightouch
  • Zapier

Automation

Everything depends on someone doing it by hand.

The situation

Lead routing, list hygiene, reporting, follow-ups. The process works only because a person chases it. When they go on leave, the system stops.

What gets built
  • Manual, repeatable processes mapped as they actually run
  • Automations and agent systems with shared context, not isolated chatbots
  • Routing, enrichment, and alerts that run without babysitting
  • Handover your team can operate without me in the loop

Activation

We're sitting on data we've never used.

The situation

Years of customer history doing nothing. Acquisition is funded; retention and reactivation are still spreadsheets and hunches.

What gets built
  • Pipelines that make historical data operational
  • Audiences synced to ads and lifecycle platforms automatically
  • Winback and lapse flows that trigger themselves
  • Churn and high-value signals surfaced while there's still time to act

Tooling

We need something that doesn't exist yet.

The situation

No vendor sells the thing you need. An internal tool, a product capability, or a workflow that has to be built around how your business actually works.

What gets built
  • Scoped product or internal tool from idea to shipped
  • Data model, backend, and front end built as one system
  • AI-assisted reporting or tooling where it earns its keep
  • A repo and architecture your team can keep shipping on
  • Next.js
  • Node.js
  • GCP
  • BigQuery
