Founder · Growth & Systems Builder

I work at the intersection of paid marketing, operations and technology. I don't just plan campaigns or hand systems off to developers. I build the tools behind them.

Across paid acquisition and custom business systems, my work includes Meta, TikTok and Google Ads, AI-powered lead generation, operational dashboards, CRM and API integrations, serverless workflows, and custom tools built with Claude AI, Cloudflare, React, Airtable, Gmail and Calendly.

06 / Marketing Operations

Free Trial Lead Automation

Three linked automation systems routing free trial leads from a Meta ad to the right caller in seconds. Database-free round-robin rotation, repeat-lead screening that flags history before anyone dials, and completion alerts that fire exactly once, all built from Meta Lead Ads, Activepieces, Airtable and Discord.

07 / Marketing Operations

Lead Allocation Engine

One dashboard-controlled worker that replaced roughly forty near-identical automation flows, each carrying its own hardcoded caller list and notification map. Adding, pausing, or removing a closer went from dozens of manual edits to a single toggle, with an ownership rule that stops repeat leads getting reassigned away from the closer who already owns them.

~40 Flows collapsed into one
1 Toggle to update rotation

BEFORE: Dozens of edits per rotation change, duplicate assignments, silent failures

08 / Marketing Operations

AI Ad Creative Studio

An internal app that writes ad copy from four live sources instead of memory: the business's own ad performance data, real customer pain points mined from chat and calls, current trends, and competitor activity. Every ad checked against house copy rules before it ships. Designed, built and deployed in one working day.

09 / Marketing Operations

CEO Ad Spend Dashboard

A single screen showing what a lead or a sale actually cost, reconciled from the ad platform, the online store, and the sales team's own chat, not from Meta's Ads Manager. Built in an afternoon with no new vendor, after platform-reported numbers turned out to be roughly three times too good.

3x Real cost vs platform figure
5 of 6 "Purchases" not clean ad wins
$0 Platform cost

BEFORE: Inflated leads, sales-assisted purchases counted as ad wins

How I Work

Strategy first.
AI handles the code.

The bottleneck in building great tools is no longer coding. It's knowing what to build and how systems should connect. That's the marketer's edge.

01
🔍

Problem Definition

Identify the exact operational pain point, map the current workflow, and define what success looks like in measurable terms.

02
🏗️

System Architecture

Design the data flow, integration points, and tech stack before touching any code. Serverless-first for zero infrastructure cost.

03
⚡

AI-Assisted Build

Use Claude to generate frontend, backend, and integration code through precise prompting. Iterate conversationally until it works.

04
🚀

Ship & Measure

Deploy to Cloudflare Pages or similar free-tier hosting, connect integrations, and validate against the original business metrics.

Tech Stack
