# Intro call with Davor Minchorov

> A video call about your PHP product and what you are trying to achieve. We'll cover: - What the product does and where the software is getting in the way - Whether you need something built, modernised, or someone to lead the technical work - How I would approach it, and whether I'm the right fit It helps if you can share a few lines about the product, the stack, and the team size when you book. If it looks like a fit, I'll follow up with a written plan before any work starts. If it doesn't, I'll tell you, and point you somewhere better if I can.
