## Event types

- [15-min quick question](https://cal.com/sohag-pro/quick): 15 min, confirmed instantly, event type id 5740921. One concrete question, one short answer.

Open slot for hiring conversations, freelance briefs, or a problem you want a second pair of eyes on. Bring the context: who you are, what you're building, what you'd want me to help with. Async by default - pick a slot only if a call actually moves things faster. Details: https://cal.com/sohag-pro/intro.md
- [45-min architecture review](https://cal.com/sohag-pro/architecture): 45 min, confirmed instantly, event type id 5740920. Bring a diagram, a Notion doc, or a repo link before the call. We'll walk through the system, surface the load-bearing decisions, and stress-test the ones you're least sure about. Backend, payments, AWS infra, Laravel / Next.js stacks are where I'm strongest.
