I turn scattered marketing data into a single, revenue-driving source of truth. For the past decade I’ve built and scaled attribution engines, server-side tracking stacks, and automation workflows for brands that spend six to eight figures on ads. My specialty is stitching every click, session, and purchase—web or app, online or offline—into one clean ledger that ad platforms, BI tools, and executives can finally trust. What I deliver • Accurate, cross-device attribution – deterministic IDs first, probabilistic backups, zero credit leakage • Server-verified conversions – Cloud Functions/Lambda endpoints, de-duplication, offline uploads to Google Ads, Meta, TikTok, SKAN • Actionable journey mapping – Users → Sessions → Events modeled in BigQuery or Supabase, surfaced in Looker Studio and Power BI • AI-driven optimization – predictive LTV scoring, anomaly detection, and auto-bidding scripts that adjust spend before budget burns • Workflow automation – Zapier, n8n, and custom Python orchestration that slash data-ops time from hours to minutes Tech I speak fluently Google Tag Manager | Google Ads & GA4 APIs | Appsflyer | Segment | BigQuery | Supabase | Python | JavaScript | Cloud Functions | Looker Studio | Zapier | Airflow | AWS & GCP When an enterprise brings me in for a full-scale attribution and automation overhaul, three categories of outcomes follow—structural, financial, and cultural. 1. Structural gains • One canonical data spine—every click, device, login, and transaction tied to a single customer key and stored in a warehouse the entire org can query. • A hardened server-side event pipeline that de-duplicates, validates, and routes conversions to Google, Meta, TikTok, affiliate networks, and downstream BI tools within seconds. • Production-ready documentation, runbooks, and monitoring dashboards so Engineering, Marketing, and Compliance share the same map and alerting. • Privacy and regulatory guardrails baked in (GDPR, CPRA, state gaming rules, Apple SKAN), reducing legal exposure before it surfaces. 2. Financial impact • 15–30 % cut in wasted ad spend as smart-bidding algorithms finally learn from true revenue, not last-click noise. • Faster payback periods on campaigns because late or offline conversions are captured and credited back to the original spend. • A clear line of sight from marketing cost to customer lifetime value, enabling budget reallocation at quarterly planning without guesswork. 3. Cultural shift • Marketing stops debating whose spreadsheet is “right” and starts iterating on creative, offers, and channels supported by a single source of truth. • Data and Engineering teams reclaim hours previously spent reconciling reports; that time moves to high-leverage analysis and automation. • Leadership gains real-time KPIs—cohort LTV, channel ROAS, churn risk—refreshed automatically, sparking evidence-based decisions at board level. In practice, enterprises see campaign insights that used to take weeks surface overnight, promotions tuned mid-flight, and cross-functional teams rallying around shared metrics instead of siloed reports. The stack I leave behind is modular and documented, so your internal teams can extend it—adding new regions, business units, or predictive models—without another ground-up rebuild.

I'm Sean Kelly, a data analytics professional with a decade of experience helping organizations turn raw data into clear, actionable insights. Raised just outside Washington, DC, I earned a bachelor’s degree in Economics from the University of Maryland, College Park, building a strong foundation in data-driven decision-making. I began my career as a digital marketing specialist at Blue Corona, a startup that ignited my passion for data. There, I discovered the transformational power of analytics tools like Google Analytics—tools that democratize data and empower even small businesses to make smarter decisions. Eager to deepen my technical expertise, I earned a postgraduate diploma in Statistics from the University of Glasgow in 2016. This gave me a strong foundation in statistical analysis and quantitative thinking, which I now apply to real-world business challenges. Since then, I’ve worked with some of the most innovative tech startups and growth-stage companies—WeddingWire, The Knot, Capsule, Caribou, and Expel—where I specialized in building automated reporting pipelines, scalable dashboards, and KPI frameworks that drive clarity and accountability across teams. I’m fluent in SQL and R, a power user of Excel and Google Sheets, and deeply experienced with business intelligence platforms. But what truly sets me apart is my ability to bridge the gap between technical detail and business strategy. Whether I’m designing a self-serve dashboard for a product team or uncovering insights for executive leadership, I focus on clarity, speed, and business impact. I’m now offering my services as a consultant to help organizations solve their thorniest data challenges, build smarter reporting systems, and turn information into action. If your team needs a data expert who delivers insight—not just reports—I’d love to connect.

I have a PhD in Psychology, I've worked as a behavioral scientists and data analyst for major brands, and I started my own software company. But what I enjoy most is communication. Clear, concise communication. It my sound strange, but I find my Zen boiling down complex information into clear, actionable insights. I apply an ease-of-understanding criterion to everything I do (some might call this "UX communication"). Throughout the course of my career, this has included: • Data insight decks • Whitepaper writing (for academic journals, patents, and technical reports) • General content writing (for blogs and general audiences) • Website design & copywriting So, if you need help effectively communicating in any of these areas, send me a message! I am also available for general data analysis (using Pandas with Python or R) and can create original content in any of my areas of expertise: • Psychology (in particular, Vision Science, Behavioral Science, and Evolutionary Psychology) • Experimental Design / Experimental Methods • Data Science and Statistics

My strongest skills are in data presentation and dashboarding, including my four expert witness reports and numerous academic research articles. See my resume for online examples of my work. I can run any variant of the regression model, including time series, and present your data with R tools including ggplot2 and gganimate. I am also available to offer second opinions on other expert witness reports, including everything from "eyeballing" the code all the way up to full replication. My strongest specialty is demystifying data and presenting it accessible, layperson's terms.
