I’m Mujib Sheikh, Founder & CEO of CartPer, founder and creator of Doorabag, and a full-stack developer focused on marketplace platforms, business systems, automation and growth.
Founder & CEO of CartPer
I work at the intersection of entrepreneurship, product development and technology. My approach is practical: understand the real operational problem, design the right system, build it, test it and improve it.
I founded Doorabag, developed its platform and built the brand from the ground up. After leaving that venture, I started building CartPer as a technology-enabled home-services marketplace based on a city partner model.
I also develop platforms for clients. ScraPan is one such client project—a scrap marketplace product designed and developed as a complete digital system.
From business concept and brand positioning to product architecture, development, operations and growth.
A technology-enabled home-services marketplace connecting customers, city partners and service professionals through structured booking, estimate, assignment, billing and warranty workflows.
Founded, developed and built as a home-services brand and digital platform. I am no longer associated with the venture, but it remains an important chapter in my entrepreneurial journey.
A scrap marketplace platform developed for a client, including customer booking, partner operations, live workflows, mobile experience and notification systems.
I combine product thinking, engineering and growth execution to build systems that work in the real world.
Booking flows, partner systems, technician allocation, estimates, billing, commissions and operational dashboards.
Responsive web products and business systems using PHP, MySQL, JavaScript, APIs and secure backend workflows.
Flutter applications, WebView products, Firebase Cloud Messaging, real-time alerts and mobile-first experiences.
Clear customer journeys, high-intent service pages, conversion-focused interfaces and practical usability improvements.
Technical SEO, city landing pages, search strategy, Google Ads, conversion tracking and campaign optimisation.
Notifications, lead distribution, reporting, partner credits, customer updates and process automation.
My experience comes from building, operating, debugging and improving real platforms—not only from writing code.
Developed practical skills across web development, databases, interfaces, SEO and digital operations.
Founded the venture, created the brand and developed the platform, gaining first-hand marketplace and operations experience.
Created a city-partner-led home-services platform with structured technology, business workflows and growth systems.
Designed and developed products such as ScraPan, converting business requirements into complete digital platforms.
