The Problem We Were Actually Solving
Our initial research led us to believe that the payment processors weren't supporting Venezuelan transactions due to local regulations or restrictive business practices. We tried reaching out to all four platforms, but their standard responses indicated that their services were unavailable due to various reasons such as "geographic restrictions" or "inability to support local currencies." This was both disheartening and concerning - we had customers relying on us, but our hands were tied.
What We Tried First (And Why It Failed)
As a stopgap measure, we explored alternative payment methods like cryptocurrency and mobile payment services offered by local banks. These solutions had severe limitations. Some only accepted small transactions, while others required extensive documentation and identity verification, making it difficult for both buyers and sellers to navigate the complex regulatory environment. These alternatives also struggled with security and trust issues.
The Architecture Decision
We decided to take a different approach. Instead of relying on external platforms, we chose to build our own commerce system from scratch, leveraging the resources and expertise of our team. We opted for the Rust programming language due to its focus on performance, memory safety, and control over the architecture. Although we knew the learning curve would be steep, we believed this would give us the flexibility to adapt and evolve our system in response to the ever-changing regulatory landscape of Venezuela.
What The Numbers Said After
After a year of development and testing, our homegrown commerce system was finally live. We used a combination of profiling tools and metrics to gauge its performance. The results were striking: we saw an average latency of 200 milliseconds per transaction, compared to the 10 seconds or more we experienced with external payment processors. In addition to faster transaction times, our new system also boasted a significant reduction in allocation counts, indicating improved memory efficiency. This not only enhanced user experience but also reduced the risk of unexpected crashes and security breaches.
What I Would Do Differently
While our homegrown commerce system has proven to be a resounding success, there are areas where we would invest more time and effort if we were to start over. For instance, we would prioritize building stronger integrations with popular digital wallet services and cryptocurrency exchanges. These partnerships would give our customers more payment options, increasing the overall user experience and growth potential. Additionally, we would focus on optimizing our system for even lower latency and higher throughput, exploring alternatives like distributed transactions and load balancing to handle the influx of users during peak periods.
