Featured Projects & Case Studies

Project 1: Client Retention & Business Intelligence Dashboard

Challenge:
A high-value client was on the verge of contract termination, frustrated by an ineffective manual reporting process that failed to integrate crucial data (SQL, Search Term reports, Helium 10) and provide clear strategic insights.
Action (Adaptive Solution):
To save the partnership, I independently architected a full-stack BI solution.
  • Backend Engine: Developed a backend using Python and Pandas to automate the ingestion, cleaning, and analysis of all required data sources.
  • Frontend Dashboard: Created a professional, intuitive Looker Studio dashboard. This key deliverable transformed complex data into simple, actionable visualizations.
  • Strategic Engagement: Led a high-stakes meeting where I successfully shifted the client's focus from operational complaints to strategic planning, using the new dashboard to guide the conversation.
Impact:
  • Retained a high-value client at a critical breaking point, turning frustration into a renewed, strategic partnership.
  • The client praised the solution for providing the insights they "really needed to know."
  • Demonstrated the ability to solve a critical business problem single-handedly with a full-stack solution.

Interview Q&A: Talking Points

Q: How do you approach reporting and data analysis?

My approach is to create a clear, actionable story from the data that is tailored to the team's workflow. I always start by defining the primary business goal, whether it's profitability, market share growth, or a new product launch.

Q: Tell me about a time you used data to find an insight.

A client's overall ACoS was rising despite flat ad spend. I combined their Search Term Report with Business Reports by ASIN and quickly discovered two issues: 1) wasted spend on an irrelevant search term, and 2) a quiet conversion drop on their top ASIN.

The solution was a negative keyword strategy and a main image refresh. The result was a 15% reduction in ACoS and a restored conversion rate, directly improving their bottom line.

Q: How would you handle a complex catalog with thousands of ASINs?

That's a challenge where my adaptive skillset truly shines, as large catalogs require systematic, not manual, solutions. My approach depends on the team's capabilities, ranging from custom Python scripts for full automation (like my WesAI project) to robust, formula-driven Excel/Sheets templates for streamlined manual management.
