Growth marketer managing $20M+ in multi-channel media at Universal McCann. I build automated workflows that multiply my team's output and eliminate busywork.
What I Build
At Universal McCann, I manage multi-channel strategy and planning across both digital and traditional channels — from paid social to linear TV — working with partners like Meta, Amazon, and Walmart, consistently exceeding KPI benchmarks and delivering measurable brand lift above industry standards.
Beyond managing a team and presenting optimization strategy to C-suite clients, I also build the tooling. I've created automated workflows that cut ad copy creation from 2 hours to 15 minutes, cut launch errors by 25%, and eliminated hours of manual platform-switching — the kind of work that usually requires a dedicated engineering team.
Built a workflow that ingests hundreds of live ads with performance data, flags underperformers, and generates new headline and description variations at scale. What used to take the team two hours of manual iteration now runs in fifteen minutes.
2hrs to 15min — ad copy creation time
Built an automated workflow that handles campaign trafficking and QA by processing spreadsheet inputs, validating placement details, and flagging errors before launch. Cut launch errors by 25% and improved speed-to-market by 3 days.
25% fewer errors, 3 days faster to market
Built a custom Meta Ads API integration that pulls campaign performance, spend, and ad effectiveness into a single interface — eliminating the need to toggle between platforms during optimization cycles.
Real-time insights, zero context switching
Designed a system that logs hypotheses and results across ad iterations, then feeds prior learnings into each new round of creative generation. Every test makes the next one smarter.
40%+ improvement in test-over-test performance
