The story so far

From a ₹2 first business to building technology platforms.

My name is Mujib Rajjak Sheikh. I am an entrepreneur, product builder and full-stack developer from Maharashtra, India. My journey has moved through street-side selling, electronics, repair services, sales, food businesses, field work and software development— but the central idea has remained the same: build something useful and keep moving forward.

01
Roots

An entrepreneurial instinct that appeared early.

I was born in Kingaon Raja in the Sindkhed Raja region of Buldhana district. My early childhood was shaped by a hardworking family, village roots and the example of my father, Rajjak Sheikh, who put family responsibility before personal advancement.

In 1998, our family moved to Aurangabad. While studying in school, I started my first small business in the seventh standard with ₹2 borrowed from my mother. I bought basic material, sold paan from a small wooden box and turned ₹2 into ₹6. I returned the ₹2 the same evening and reinvested the balance.

That small experiment quickly became a pattern. I sold bhel, groceries, vegetables and fried papad during Ramadan. I rented a child-sized bicycle, travelled to wholesale markets and brought products back to sell after school. Long before I knew words such as “working capital” or “customer demand,” I was learning them through experience.

“The amount was small, but the lesson was permanent: earn trust, return what you owe and reinvest in the next opportunity.”

02 Wardha years

Electronics, responsibility and rebuilding through work.

Our family later moved to Wardha, where I continued school. My attention naturally moved toward electronics and mechanical experiments. I enjoyed making things, understanding how they worked and trying ideas with whatever material was available.

Life also brought responsibility early. My father suffered a serious illness and passed away in 2009. During those years I worked in a tea shop, delivered tea to offices, helped run a small food business and travelled to sell mobile phones in nearby towns.

I eventually returned to education, completed my secondary and higher secondary studies in science, and began learning mobile repair alongside college. The combination of electronics, customers and business felt natural.

03 2012 onward

Turning technical skill into a service business.

In 2012, I started operating a mobile service centre. As the business grew, I worked with multiple handset brands and developed experience in customer service, repair operations, team handling, inventory and brand processes.

The business performed well for several years, but market disruption, changing handset economics and the pandemic gradually reduced the repair opportunity. Financial pressure increased and the business that once provided stability could no longer support the future.

That period taught me a difficult but important principle: a successful business model is never permanent. Markets change, and an entrepreneur must be prepared to learn again.

04 Starting again

No work was too small when the responsibility was real.

I explored several paths after the mobile-services downturn. I worked on a refurbished two-wheeler concept in Pune, took my first formal corporate role, handled sales responsibility across Chhattisgarh, worked briefly in the cement industry and attempted product and food businesses.

At one point, my wife and I would wake up around 3 a.m., prepare poha and sell it outside a stadium in Nagpur. Some days the product did not sell. We still returned the next day. I also worked on a roadside food stall before local enforcement required us to move.

These were not detours from entrepreneurship. They were the years that taught me humility, customer behaviour, cash flow, resilience and the importance of solving a genuine problem.

The turning point

Field experience met technology.

An opportunity in home-appliance repair introduced me to structured service operations. I worked in the field, learned the trade and helped another technician learn it as well. At the same time, I studied coding, software systems and emerging technical subjects.

I began to see the service industry differently—not only as a technician, but as a product builder. Every booking, technician assignment, estimate, payment, warranty and customer update could be organised through better technology.

05 Doorabag

Building a home-services platform day and night.

I founded Doorabag with partners as a home-services venture. When outsourced development did not produce the platform we needed, I took responsibility for the product myself.

I worked in the field during the day and developed the platform at night, often sleeping only a few hours. I created the brand, designed the business workflows and built the technology that allowed the venture to launch in June 2025.

As the venture grew, strategic and financial differences emerged among the partners. In June 2026, I chose to leave Doorabag and transfer my involvement to the remaining partners. I am no longer associated with the venture, but building it remains one of the most important chapters of my journey.

The next chapter

CartPer was built from confidence, not comfort.

People close to me asked how I could walk away from something I had created. My answer was simple: I had built one brand, and I believed I could build another.

I started CartPer as my independent home-services marketplace and applied everything I had learned—from field service and partner operations to software architecture, SEO, paid acquisition, customer experience and automation.

What guides me

Principles earned through experience.

01

Start with what you have

A small beginning is still a beginning. Resources can grow after initiative begins.

02

Learn the operation yourself

Products become stronger when the builder understands the customer and field reality.

03

Failure is information

Every closed business and difficult phase can improve the next decision.

04

Build again

A brand may be left behind, but the ability that created it stays with the builder.

Today

Building CartPer and technology products for other businesses.

Today I am focused on growing CartPer while developing complete digital platforms for clients. ScraPan is one such client project that I designed and developed as a marketplace system.

My work now combines product planning, full-stack development, mobile applications, Firebase notifications, business automation, UI/UX, SEO and performance marketing.
