Project MARKETPLACE: Commerce Hub Platform

Objective: Develop a scalable ecommerce backend platform for an intra-global retail market place within the

agent and partners (intra-commercial space for internal clients).
Team Size: 20+ developers, engineers, and senior developers.

• The platform handled over 500,000 transactions per day during peak periods. Initial issues with transaction latency were addressed by optimising Kafka configurations and improving Postgres indexing, resulting in a 20% increase in processing speed.
• Scaling the backend platform to manage over 1 million concurrent users required robust load balancing and microservices design. Challenges in load distribution were resolved by fine-tuning microservice instances and deploying auto-scaling strategies, improving traffic handling by 30%.
• Managing vast volumes of customer and transaction data required both structured (Postgres) and unstructured (MongoDB) storage. Faced with slow query performance during high traffic, database optimizations improved data access times by 25%.
• SWIFT payment integration posed challenges in handling cross-border transactions and compliance. Implementing additional security layers and streamlining the payment process resolved these issues, reducing transaction failures by 15%.
• Cloud infrastructure costs were reduced by 25% through the use of automated scaling and resource optimization strategies, balancing cost with high availability during peak usage.
