FullStack Developer for AI Booking SaaS Development (Multi Tenant, LLM, Calendar Sync, PWA)
Working with Ammar was an excellent experience. He takes full ownership of the project and thinks like a senior engineer, not just a developer. He helped us design the right architecture, communicated clearly at every step, and consistently delivered high-quality work on time. Very solution-oriented and dependable. I would confidently hire him again for future projects.

Urgent Fix for Supabase RLS Policies + Multi-User Admin & Team Features
Excellent developer! He did everything I asked and went above and beyond. Ammar was always available and had GREAT communication. Completely committed to finishing the task within the timeline. He has a great depth of knowledge in his field. I'm upset I hadn't found him sooner but will definitely be using again going forward! HIGHLY RECOMMENDED!
