Ismail AbuHasanein

I build AI products and SaaS platforms that hold up in production.

I'm Ismail, a senior software engineer with ten years of full-stack work behind me. I designed, built and run SoutFlow, a voice AI receptionist that answers calls, books appointments and hands over to people. Before that I shipped marketplace apps for Jira and monday.com, and multi-tenant SaaS on Laravel and Node.js.

My own product, live and taking calls

SoutFlow AI

Voice AI receptionist for businesses. Founder and full-stack engineer.

A real-time speech-to-speech agent that works over the phone, WhatsApp and a website widget. It checks live availability and books appointments, answers from the business's own documents, and lets a human operator take over a call in progress. Multi-tenant, in English and Arabic, with subscription billing.

What I take on

AI agents and LLM features

Voice and chat agents that do real work: book the appointment, look up the order, hand over to a person. Grounded in your own documents with RAG, and reachable by phone, WhatsApp, a web widget or inside tools like Jira.

SaaS platforms and integrations

Multi-tenant backends, roles and permissions, billing, and the integrations that make a product useful: Stripe, Twilio, WhatsApp, Jira, monday.com, payment gateways and government services.

Review and rescue of existing code

A senior second look at a product that was built fast, by a team or with AI tools. I check security, tenant isolation, performance and deployment, give you a written list of what to fix first, and can do the fixing.
