In software engineering, AI layoffs are already here. If you’re sending resumes and hearing nothing, you’re not unlucky—you’re early. Humans learn after work. Algorithms learn 24/7. 2 moves: 1.Own AI (invest). 2.Use AI (build your brand + products on

AI stocks feel exactly like 1998. Here’s the trap: even if it’s a bubble, you still don’t know when it pops. Bubbles usually end from macro (rates↑ / inflation↑ / unemployment↑) — not vibes. 🎥 Full breakdown - checkout out my YouTube video: youtube.com/watch/p3ZhKcqA…

Ever feel trapped as “just a backend dev”? That was me: tickets, databases, infra… great training, but I wanted to build products end-to-end. So I started shipping tiny tools at night/weekends. No hype. No AI magic. Just solving one clear problem. Fast forward: 3 products →

A rule that changed everything for me: I only build ideas that almost can’t fail. Not shiny “never-been-done” stuff (that needs validation + market education). Instead: 1.Find tools already making $$ with terrible UX 2.Ship the same core value — 10x nicer, clearer pricing,

How do I launch product after product without burnout (or going broke)? I don’t rely on inspiration. I run a playbook: 1.Pick a proven problem (tools already making $$, but clunky) 2.Build the smallest useful v1 fast 3.Charge from day 1 (free users give opinions,

Day 4 of #BuildInPublic Sharing a new prompting insight I just learned. This is the wrong way to prompt AI “You are a world-class expert…” That advice is outdated. Modern models don’t need a persona. They need you. In my latest video, I will explain in details! If you
