Four takeaways from Anthropic's developer conference in San Francisco โ rapid growth, context switching as a superpower, customization gaps, and Slack-native AI workflows.

Spoke at Stanford's Society of Latinx Engineers about breaking into industry, early career decisions, and AI tooling โ one of those Q&As where you can tell people are genuinely curious.

Presented on AI tooling and the agentic future alongside Ashwin Goel for Salesforce's Futureforce intern cohort โ sharing how Slack and Salesforce are building for what comes next.

Contributed to Gregor Ojstersek's Engineering Leadership newsletter โ one of 15 engineers sharing how we're actually using AI in our day-to-day workflows.

Slack completely redesigned its notification system to address user overwhelm, migrating from four conflicting preference models to a unified system with three clear options. This architectural overhaul separated notification content from delivery method, giving users independent control over what activities trigger notifications and which devices receive push alerts.

Shipped sidebar improvements to Slack including channel indentation, smart breakpoints, consistent padding, and default section icons โ a thoughtful glow-up that improves usability without disrupting familiarity.
