Denny Biasiolli

Denny Biasiolli is an independent full-stack developer based in Italy. He builds web applications using Python, Django, Vue.js, and Rust, focusing on practical solutions to chronic backend challenges.

Logic around timezones is notoriously fragile. His talk on building timezone-safe applications breaks down why simple datetime math fails during daylight saving shifts, and how to fix data layers by storing user intent instead of just raw UTC offsets.
