Designed and developed a 25% faster payment processing service and a new payment workflow (~4k payments/day). Built a Go (Fiber) service aggregating exchange rates from multiple providers (~20k requests/day). Implemented a back-end Go service to batch-process blockchain confirmations (~10k/day) and publish confirmations to RabbitMQ. Integrated multiple blockchains (Solana, Cardano) (~5k transactions/day). Implemented Seq-based logging for logs storage, increasing discovery of potential bugs by ~40%. Built system API and integrated numerous services and blockchains via REST API, RPC and gRPC. Refactored data loading and DB queries to remove bottlenecks and improve performance; documented features in Confluence.
