GuaxiCast

technology, business, entrepreneurship · EN

After years in data science — co-founding Hekima (acqui-hired by iFood) and leading Recommendation Data Science there — Luiz Felipe Mendes left a stable job, took a sabbatical, and went back to the keyboard to build the apps he always wished existed. GuaxiCast is the audio companion to his writing: short, candid episodes about building software with AI sitting right next to you. Expect honest field notes on vibe coding, the real cost of AI dev, choosing the right model for the right task, the Skills/Rules/Agents meta-layer, data science, and the messy reality of shipping products solo. It's building in public, the unfiltered version — more GitHub links than follower counts, more shipped apps than hot takes. Brewed with curiosity and a lot of specialty coffee. ☕ New episodes are drawn from essays on Medium, reimagined as quick conversations you can take on the go.
