Flex — Building an AI-powered operating system for restaurants

Muhammad Talha Sultan

Cofounder & CTO at Flex · Full-stack software engineer · Flutter developer

I'm building conversational AI for restaurant operations. My background spans Flutter and native mobile development, backend services, and the integrations that connect them. Outside of building software, I love to read.

Building Flex

Flex is an AI restaurant operating system and point of sale for restaurants, cafés, and hospitality teams. It brings together ordering, payments, kitchen operations, reservations, and marketing so teams can manage their day from one place.

We're building FlexBot so restaurant teams can ask for help with everyday tasks in plain language. That could mean setting up a marketing campaign or finding ways to encourage repeat visits. Behind the conversation, specialised assistants support areas like operations, loyalty, and analytics.

On the engineering side, I focus on what happens after someone makes a request. How do we route it to the right assistant, check that the person has permission, and make sure a retry doesn't run the same action twice? I'm also interested in how we evaluate these workflows and keep response times practical during a busy service.

Skills and tools

  • Mobile — Flutter, Dart, native Android with Kotlin and Java, and iOS with Swift
  • Backend and integrations — Python, TypeScript, Go, and REST APIs
  • Architecture and testing — Clean Architecture, MVVM, test-driven development, and unit testing
  • Applied AI — Conversational workflows, task routing, permissions, and evaluation

Some public projects

  • Sirat-E-Mustaqeem — An Islamic app with Quran reading, prayer times, Hadith, and Qibla direction.
  • Expense Flow — Your finances. Your data. Built in the open.
  • Calendar Timeline — A Flutter widget for picking dates on a horizontal timeline.
  • Flutter Food Delivery App — A Flutter example exploring the food-ordering experience.
  • Slide to Act — A Flutter widget for confirming an action with a slide gesture.
