Independent · Data & Martech Systems

I build and fix the systems growing companies run on.

Tooling, tracking, and growth data that should be working together, but aren't. I map the system, then build it myself. One person, end to end.

02 · How a project runs

One line, from mess to system

There's a clear path from mess to system. You always know where we are on it.

01
Map
Gather requirements

A short discovery phase. I audit what exists: tools, tracking, data flows. Then I clarify what "done" looks like.

02
Design
Architect the solution

Before anything is built, I design how the pieces should fit: systems, data, and integrations scoped to the problem.

03
Build
Implement & integrate

The work itself: pipelines, tooling, CRM, lifecycle, ads, analytics, connected to the same source of truth.

04
Verify
QA & verification

Testing, monitoring, and data-quality checks so silent breakages get loud before they cost you.

05
Amplify
AI enablement

Agents and automations layered onto the clean foundation: enrichment, anomaly detection, reporting that writes itself.

06
Grow
Sustainable growth

A system your team runs confidently without me. Or with me on retainer, quietly keeping it sharp.

03 · What I build

Systems, not slide decks.

Growing companies usually arrive with one of these. I find the system underneath, then build the fix into how you already run.

04 · What this looks like in practice

Recent case studies

Snapshots from real projects across different stacks and industries.

DTC / Ecommerce

From spreadsheet reporting to a live growth stack

A DTC brand running paid across Meta and Google, reporting in spreadsheets, with no idea which channel actually drove repeat purchases. I built the event schema, piped everything into a warehouse, and connected revenue back to campaigns.

B2B SaaS

One source of truth across product and marketing

A SaaS team whose product analytics, CRM, and ad platforms all told different stories. I rebuilt tracking on a clean schema, unified identity across tools, and gave marketing and product the same funnel for the first time.

1 funnel
everyone finally agrees on
Bookings / Wellness

Booking data turned into retention revenue

An appointment-based business sitting on years of booking history it had never activated. I synced lapsed-visitor and high-value segments from the warehouse to paid and email channels, with winback flows that run themselves.
