I build the paid media campaigns, data pipelines, AI systems, and automation that turn ad spend into predictable revenue. From LLM-powered lead scoring to server-side tracking infrastructure — I bridge the gap between your CMO and your CTO.
I build the marketing systems that most marketers just use. The gap between your CMO and your CTO — that's where I work.
As founder of Lux Marketing Agency (est. 2018), I've served 30+ clients across 6 industries — implementing profitable marketing funnels, formalizing sales pipelines in HubSpot, and managing up to $75K/mo in combined ad spend. I also run AI workshops teaching business professionals prompt engineering and custom tool building (Session 1 sold out).
As Head of Growth at Glossi, I built an LLM-based lead scoring system that fed quality signals back into Google Ads, set up a Pinecone RAG knowledge base used company-wide, and analyzed every customer conversation using custom JSON schemas to directly influence product direction. The data infrastructure I built — NGINX, Jitsu, BigQuery, identity stitching, bot detection — generated 2x the sign-ups compared to the sales team.
I write PHP, JavaScript, and SQL. I build WordPress plugins, SaaS products, and LLM pipelines. This site is hand-coded — no frameworks, no CMS, no templates. My measurement-first philosophy means I build tracking infrastructure before spending ad dollars.
B2B SaaS / AI-Powered Growth
Led full-stack growth as Head of Growth: built an LLM-based lead scoring system feeding Google Ads, deployed a Pinecone RAG knowledge base used company-wide, and analyzed customer conversations with custom JSON schemas to shape product direction. Built data infrastructure from zero — NGINX, Jitsu CDP, BigQuery, identity stitching, bot detection — generating 2x the sign-ups vs. the sales team.
DTC E-Commerce / Conversion Rate Optimization
Took a Shopify flower company's checkout from underperforming to industry-leading in 60 days. Ran systematic A/B tests on cart page layout, added testimonial plugins on checkout, and optimized the purchase flow. No creative changes, no price changes — just conversion infrastructure.
Luxury / DTC E-Commerce
Built RFM (Recency, Frequency, Monetary) segments for a high-profile jewelry brand's Facebook Ads. No creative changes — purely data strategy. Used Facebook Pixel custom audiences to target high-value customer segments, reducing wasted spend on low-intent users.
Wine & Hospitality / Analytics
Set up Google Analytics, Tag Manager, and conversion tracking infrastructure for premium Northern California wineries including Ferrari-Carano, Jordan Winery, Iron Horse Vineyards, and Charles Krug. Built the measurement foundation that enables accurate attribution and data-driven marketing for luxury DTC wine brands.
E-commerce / Subscription Box
Full-stack marketing and technical setup: established LLC structure, built financial reports, led brand planning, launched website with compelling copy. Implemented customer onboarding with Mautic, customer service with Chatwoot and Twilio, and marketing with Jitsu CDP and Google Server Side Tag Manager. Built WooCommerce subscription model.
Non-profit / Fundraising
Developed a custom WordPress plugin integrating with Meta's Conversion API (CAPI) for real-time sales tracking, bypassing ad blockers. Ran comprehensive Facebook and Instagram ad campaigns for a major fundraising event. The custom tracking solution combined with strategic social media marketing made the fundraiser the most financially successful in the museum's history.
Real Estate / AI Tool
Built an AI-powered Listing Photography Analyzer that evaluates real estate listing photos for quality, composition, and market appeal. The tool provides instant analysis with 10+ quality metrics and personalized improvement tips to help real estate agents optimize their listings.
Vacation Rentals / AI Platform
Developed a comprehensive AI platform that analyzes Airbnb and VRBO listings to help hosts maximize bookings and revenue. The platform provides scoring across 7 categories and competitor tracking for up to 5 properties.
WordPress Plugin / E-commerce
Built a WordPress plugin that recovers 15-30% of Google Ads conversions lost to ad blockers, browser privacy restrictions, and cookie expiry. The plugin captures GCLID/GBRAID/WBRAID identifiers server-side, intercepts dataLayer events, stores conversions in a local database, and serves a Google Ads Data Manager-ready CSV endpoint for automated offline conversion imports.
Full-funnel campaign management from strategy to optimization, with server-side tracking that recovers conversions lost to ad blockers.
End-to-end process automation that eliminates manual work across marketing, sales, and customer operations.
First-party data collection, identity resolution, and unified customer profiles that power personalized campaigns.
Pipeline formalization, lead scoring, outbound automation, and B2B call center operations that turn leads into revenue.
Custom AI infrastructure that compounds — LLM lead scoring for ad platforms, RAG knowledge bases, customer conversation analysis, and AI-powered marketing tools.
Server-side tracking that recovers conversions lost to ad blockers, A/B testing, checkout optimization, and measurement-first analytics infrastructure.
