312 - Understanding Pi Durable with Mario & Armin of Earendil
About this podcast
Fragmented is an AI developer podcast for engineers who want to go beyond vibe coding and ship real software.
We cover AI-assisted development the way working engineers actually use it: prompting strategies, code review, testing, debugging, workflows, and building production-grade software with AI tools. No hype. No "I shipped a SaaS in a weekend" stories. Just tactics that work.
Hosted by Kaushik Gopal and Iury Souza — software engineers using AI daily to build and ship real products.
From vibe coding to software engineering — one episode at a time. Our goal: help you use AI to become a better engineer, not be replaced by one.
