Calvin Wang developed a batch middleware feature for the smartcontractkit/chainlink repository, focusing on optimizing bridge HTTP requests. By enabling batched processing of these requests, Calvin improved throughput and reduced latency, directly addressing the need for faster and more efficient data delivery in on-chain integrations. The solution leveraged Go for backend development, with particular attention to concurrency and API design. This work laid the foundation for handling higher request volumes and contributed to a more responsive user experience. Over the month, Calvin concentrated on incremental feature delivery, demonstrating depth in backend middleware architecture and performance optimization without addressing major bug fixes.
