Azure/Databricks Streaming: Developed a restaurant analytics platform processing 80,000+ events/day, cutting reporting lag from 6 hours to under 3 minutes. Kafka/Snowflake Pipeline: Engineered a real-time stock market data pipeline tracking 120+ tickers with under 8 seconds end-to-end latency. I write clean, documented code your team can maintain long-term and provide transparent daily updates. Message me with your data challenge and I’ll walk you through exactly how to solve it.

Expert Vetted | Founder of Maven My company is designed to help agencies track their client's complete customer journey - from first impression to closed deal and repeat purchases. I've built attribution and reporting systems for companies from Fortune 500 (HCA Healthcare, Mars Inc.) to high-growth DTC brands (+$500m Revenue). My specialty is in building full-funnel reporting for lead or eCommerce based campaigns. I help companies stitch performance of a campaign: - from impression to closed deals for lead based campaigns - from impression to conversion and returning purchases for eCommerce based campaigns. We use the same stack across all projects to keep things accurate, and allow for rapid changes over time to reports or data models: - Maven (Data Integration) - dbt (Data Modeling) - BigQuery (Data Storage) - Looker Studio (Data Visualization) Our team also has expertise in GTM so we can manage the entire tracking and analytics implementation from start to finish to give you a full view of your customer journey - from webpage visit to CRM or eCommerce platform. If you're an agency help to improve your attribution, move away from manually created reports, and improve client retention, please feel free to reach out!

I learn how your business works and build the analytics your team needs to run it. I've done this for 50+ clients across financial services, healthcare, staffing, manufacturing, and e-commerce. Every engagement follows a proven methodology designed to get you from first conversation to trusted reporting as fast as possible. This is what you get when working with me: 1. A clear starting point. We have a focused conversation where, together, we figure out what decisions your team needs to make and what information is missing. You walk away with a requirements document you can sign off on or provide feedback on. No ambiguity about what's being built or why. 2. A prioritized roadmap. I audit your systems, your data, and your current reporting. You get a clear picture of what drives real value, what can wait, and what questions your team should be asking. The noise gets separated from what matters. 3. A working product with your real data, fast. Your systems get connected, your data gets structured, and within days you're looking at your own numbers in something real. Your dashboards tell a story: what's happening, why it's moving, where to focus. When someone wants a different cut or a new question answered, the system handles it without a rebuild. 4. Answers you trust. Data quality is built into the system from day one. When a number looks off, your team can trace it to the source. When a metric moves, you'll know whether it's a real change in behavior or just the mix shifting underneath. Findings are clear. Next steps are obvious. 5. Something that lasts. Full documentation, training, and structured handoffs. If you want ongoing support, I'm here. If you don't, everything is built so your team can maintain and extend it independently. My background is in economics (UCSD) and analytics (Georgia Tech MS), with certifications across the major cloud and BI platforms. 50+ engagements. Proven methodology at every phase. Let's talk about what you're trying to accomplish.
