October's Photo A Day Challenge, Day 1: A is for ArcGIS. 🗺️ As a Developer Advocate at Esri, this choice was probably inevitable. 😅 ArcGIS is at the center of so much of what I build, teach, and share, so it felt like the perfect place to start. #FMSPAD

Save Your Photos Month - Day 3: I love living in Alexandria, so these finds from The Old Town Shop felt perfect during my first week at Esri. Four years later, I used the ArcGIS Static Maps service to map where the memory started. Apparently, even my nostalgia is spatial now. 🗺️💚

Happy National PB&J Day to one of my favorite kinds of pairings: things that just work better together. In ArcGIS Maps SDK for JavaScript 5.0, that's finally the SDK + a single CDN script tag. No more juggling separate script tags for Calcite, the SDK, and components. 🥜🍇 #ArcGIS #JavaScript

ArcGIS component idea: <arcgis-therapist> Ideal for broken popups, invisible layers, missing API keys, projection anxiety, and fragile symbology trust. 😜
