Doctor with No Coding Experience Builds a Health App on Replit in Just 4 Days

Replit, a platform that enables users to create AI-powered applications through natural language prompts, shared the story of a doctor who is developing a healthcare app without any prior coding experience. 

Dr Fahim Hussain, a general practitioner who currently works as the director of Northern Health in the United Kingdom, set out to develop an app called MyDoctor, which offers various services, including booking appointments with doctors, requesting prescriptions, tracking nutrition and habits, providing exercise and health monitoring guides, managing medication, and more.

When Hussain approached traditional app development agencies, he was quoted a price of £75,000 to £100,000. Instead, he used Replit himself to build it in four days, spending just £175. 

“I have never coded in my life, with no background knowledge at all, despite knowing a lot about technology as someone who’s interested in the space generally,” Hussain said, adding that he downloaded Replit and started exploring its capabilities. 

“Things started off slow; I didn’t really know how to prompt the agent properly, all I knew was that we had a website and I needed to connect what we did via the app,” he said. He revealed that every time he encountered something he did not understand, he simply began conversing with the AI agent. 

Once Hussain clarified his requirements, he used Replit to develop all the necessary features for the app. 

Currently, he stated that he is working with Supabase to implement the backend features, ensuring that the health data remains compliant with various regulations. 

“It’s revolutionised the way I work because we’re concentrating on the patient and the technology handles everything else,” Hussain said. In the blog post shared by Replit, the company mentioned that the app helped push the timeline of his business forward by over a year, along with creating potential for a standalone revenue stream.
