We prepared enough barbecue to last three days, but we sold through all of it on the first day. We started cooking again that same night."Explaining what motivated him to make the switch, he told Business Insider, "I now own 100% of my time."Business made big gains over timeThe Kafi BBQ quickly went viral and gained massive popularity across the state and country. Abdul-Kafi revealed that his restaurant was on track to hit Rs 37.8 crore ($4 million) in revenue this year."Last year, we generated just under Rs (21.7 crore) $2.3 million in revenue, and we're projected to reach up to (Rs 37.8 crore) $4 million this year. That said, I still haven't paid myself a single dollar since opening and have been living off of my savings," he said.The reality of entrepreneurship: 80-hour workweeksWhile many people imagine entrepreneurship as freedom from corporate life, the former engineer says the reality is far more demanding.Speaking about the workload that comes with running his own business, he admitted, "I work about 80 hours a week."The workload is significantly higher than what he experienced during his corporate career, highlighting the sacrifices often required to build a successful company. From managing day-to-day operations and employees to ensuring customer satisfaction, much of the responsibility rests on his shoulders.The high cost of running that no one talks aboutDespite the rise of Kafi's restaurant, he is optimistic about the future. He stated that the venture might have turned profitable, but they still had not paid off the initial investment, which cost around $1 million.Abdul-Kafi highlighted the high cost of running the restaurant, noting that monthly expenses exceed $215,000. This includes $125,000 for food, $50,000 for labour, and $15,000 for rent, alongside thousands more spent on marketing and miscellaneous activities.From coding to cooking: A career transformationHis journey reflects a growing trend among professionals who are choosing passion-driven careers over traditional corporate success.The transition from software engineering to the restaurant industry required an entirely different skill set. Instead of writing code and managing technology projects, he had to focus on operations, customer service, supply chains, hiring, and business growth.Despite the challenges, the venture has evolved into a multi-crore business, proving that unconventional career changes can sometimes lead to remarkable success. However, the former Google and Microsoft employee's journey offers an important lesson: a high salary does not always translate into career satisfaction.
