I'm a Salesforce CRM Analytics Architect with 14+ years of experience designing dashboards, Recipes, and integrating external data sources like Snowflake and BigQuery. Five Salesforce certifications and 14+ projects later, I still specialise in the same thing: turning complex, messy requirements into insights people can actually act on.

Impactful visualization tells the story. I like building both.

Technology keeps changing, and AI is accelerating the pace. That’s what makes this such an exciting time to work with CRM Analytics: new possibilities keep emerging, but the real value still comes from how we use them.

Now a four-time CRM Analytics Ambassador, I’m exploring where analytics, AI, creativity, and human judgment meet. Still asking too many questions—and convinced the best work starts with a good one.
