# Project Call with Luka with Luka Abramović

> A 60-minute call to figure out what you're looking to do. If it makes sense for us to work together, we'll talk about next steps. If there's a better option out there for you, I'll gladly point you to it, since what I offer might not be the right fit for your situation right now. Either way, we'll go through everything in detail. It's an hour of my time to share what I've learned from 6+ years of building software, including applications used by 300,000+ people every month. No preparation needed. Bring whatever you have today.
