This initial success was just the beginning. Nigeria's burgeoning population of sports enthusiasts, coupled with an increased interest in online sports betting, propelled them into a phase of unprecedented growth.

However, this growth was not without its challenges. The platform, initially built to handle moderate traffic, soon found itself at the crossroads of scalability and performance. As their user base expanded, so did the demands on the system. The architecture that once seemed robust now teetered under the weight of increased transactions and user interactions, especially during peak events like Premier League matches.

1.2: Challenges Faced

The scalability issues came to a head during a series of Premier League weekends. These events are akin to festivals for football fans, and their platform experienced unprecedented traffic. Users flocked to the platform to place bets, but their system, unprepared for such a surge, faltered repeatedly.

The most critical issue arose during these peak times. The server, overwhelmed by the sheer volume of transactions, went into a tailspin. Transactions entered a volatile state; some were processed, others were lost, and many hung in limbo. The result was catastrophic - not only in terms of immediate revenue loss but also in damaging their reputation for reliability.

The development team, though skilled, was unprepared for such crises. Their focus had always been on feature development and incremental improvements, not on scaling up to meet such explosive growth. The aftermath of these outages was a frantic, all-hands-on-deck situation, with the team working tirelessly to restore services and salvage data integrity.

This period was a wake-up call. It highlighted a glaring oversight in their approach - the lack of a dedicated, systematic Quality Assurance (QA) process. Testing had been an afterthought, often relegated to developers and project managers who, despite their best efforts, lacked the specialization needed for comprehensive QA. The business impact was clear: we could not sustain growth or maintain customer trust without a radical overhaul of our QA processes.
