Challenge: Integrating a New Payment Provider & Overhauling an Outdated API

Colibri Digital faced a significant challenge: they were collecting millions of sensor data points from mining and solar sites around the world. The company’s existing infrastructure couldn’t efficiently handle the volume, leading to:

• Slow data processing times, causing delays in reporting. This affected the ability to make timely decisions on mining and solar installations.

• Manual reporting processes, which were error-prone and time-consuming, leading to inefficiencies across the team.

• Scalability issues, as the data collection was expanding, making it difficult to process and analyze larger datasets.

The company needed a faster, automated solution that could handle this increasing data volume and provide real-time actionable insights for better decision-making.

Solution: Seamless Integration & Modernized API for Enhanced Performance

As a Backend Developer, I was brought in to design and implement a solution that addressed both the integration issues and the API performance challenges. I implemented the following improvements:

• Payment Provider Integration: I implemented a modular integration strategy, ensuring the new payment provider seamlessly communicated with the existing system, reducing transaction errors and downtime during the switch.

• API Modernization: I refactored the legacy API using FastAPI, which allowed us to reduce response times by up to 50%. I implemented asynchronous processing to allow for faster requests, even during high traffic periods, and rate-limiting to prevent overload.

• Scalable Infrastructure: I optimized the backend using caching mechanisms and auto-scaling techniques, allowing the platform to handle 30% more transaction volume during peak hours, without performance degradation.

• Improved Security: I integrated JWT authentication to ensure secure and fast client interactions, reducing the risk of fraudulent transactions and enhancing overall data protection.

Results: Optimized API Performance, Streamlined Payments, & Scalable Growth

The implemented changes provided significant benefits to Tradecore, leading to measurable improvements in both technical and business outcomes:

• Reduced API response time by 50%, improving transaction processing speed and user experience.

• Successfully integrated the new payment provider, eliminating previous errors and downtime. This resulted in 95% fewer transaction failures and faster processing times.

• Improved scalability: The platform could now handle 30% more transaction volume without any downtime or performance hits, ensuring smooth service even during high-demand periods.

• Enhanced security through JWT authentication, increasing trust with clients and ensuring secure, fraud-proof transactions.
