📊 GA4 · GTM · BigQuery · Looker Studio Expert | Marketing Analytics & Attribution I build end-to-end marketing analytics systems for B2B & D2C brands, Med Spas, and growth-stage companies — clean tracking, reliable attribution, and dashboards leadership actually uses to decide where to spend next. ⭐ 11+ years in digital analytics — including enterprise GA4 migrations and MarTech integrations for global software and data companies. Enterprise-grade rigor, on growth-stage budgets. ❓ Are your GA4 data, dashboards, and attribution reports driving growth decisions — or are they just noise your team ignores? Most analytics setups I inherit are broken in 3 ways: events fire incorrectly, attribution is guesswork, and dashboards show vanity metrics. I fix all three — then build the infrastructure that keeps it clean. 🔧 ━━━━━━━━━━━━━━━━━━━━ ✅ WHAT CLIENTS GET ━━━━━━━━━━━━━━━━━━━━ 📈 GA4 implementations that capture every conversion, correctly 🏷️ GTM architectures with clean data layers, server-side tagging, and Consent Mode v2 / GDPR-compliant tracking 🗄️ BigQuery pipelines that turn raw event data into business-ready models 📊 Looker Studio (Google Data Studio) dashboards that answer "where should we spend next?" — not just "what happened" 🔗 Cross-channel attribution tying Meta, Google Ads, and CRM data into one source of truth ━━━━━━━━━━━━━━━━━━━━ 🚀 WHERE I GO DEEPER THAN MOST ━━━━━━━━━━━━━━━━━━━━ 🤖 AI-augmented delivery — I use Claude AI with GA4 & GTM MCP integrations plus Python/SQL to automate tracking audits, tag creation, and reporting, so you get faster turnarounds with fewer errors 🔒 Privacy-compliant tracking — OneTrust / Consent Mode v2 setups that keep GA4, Google Ads, and Meta firing under proper consent categories, without silently losing conversion data 🔄 GA4 migrations — clean rebuilds from Universal Analytics, Adobe Analytics, or WebTrends 🔌 CRM & MarTech integration — Salesforce / Marketo + GA4 wired into one source of truth ━━━━━━━━━━━━━━━━━━━━ 🏆 RESULTS FROM RECENT ENGAGEMENTS ━━━━━━━━━━━━━━━━━━━━ ⏱️ Reduced client reporting time by 85% with an automated Looker Studio + BigQuery pipeline 💰 Rebuilt GA4 ecommerce tracking for a D2C brand, recovering 30%+ in untracked revenue attribution 📊 Built a multi-channel attribution dashboard used weekly by a CMO for $2M+ ad spend decisions ━━━━━━━━━━━━━━━━━━━━ 🤝 WHO I WORK BEST WITH ━━━━━━━━━━━━━━━━━━━━ B2B, D2C brands, Med Spas, and marketing agencies who need a long-term analytics partner — not a one-time fix. Most clients move to monthly retainers after the first engagement, because clean data is a continuous investment, not a project. 🛠️ MY STACK GA4 · Google Tag Manager (web + server-side) · BigQuery · Looker Studio · OneTrust · Supermetrics · SQL · Python · Google Ads API · Meta Ads API · GoHighLevel 📩 If you're investing $10K+/month in paid media and flying blind on attribution, or your team is wasting hours in manual reporting — let's talk.

I turn raw data into decisions — using Power BI, Python, and SQL to build dashboards and reports that clients and stakeholders actually use. I specialize in three areas where I've built real, working projects: renewable energy analytics (solar production, ROI, forecasting), cryptocurrency/mining analytics (Bitcoin mining profitability, hash rate & difficulty trends, revenue modeling), and e-commerce/sales analytics (KPI dashboards, revenue forecasting, performance tracking). I also build general BI dashboards for any industry. WHAT I DO Power BI dashboards — multi-page reports with custom DAX measures, KPI tracking, and clean, executive-ready visuals. Python data pipelines — Pandas/NumPy for cleaning, transforming, and validating large datasets. Forecasting & analytics — trend analysis, ROI modeling, and predictive reporting (e.g. Prophet-based revenue forecasting). Full data workflow — from messy raw data (CSV, SQL, APIs) to a polished, decision-ready dashboard. RECENT PROJECTS Bitcoin Mining Profitability Dashboard — 5-page Power BI report, 34 custom DAX measures, covering hash rate, difficulty, and ROI. Solar Energy ROI & Production Forecasting Dashboard — comparative analysis across two climates (Phoenix vs. London). AutoSales BI — a full Streamlit web app with a 16-KPI e-commerce/sales dashboard and 3-month revenue forecasting. I work fast, communicate clearly, and deliver dashboards that are actually usable — not just pretty. If you need someone to make sense of your data and turn it into something your team or clients can act on, let's talk.
