As a Senior Software Engineer, I’ve driven impactful projects using technologies like Go, Java, Kafka, Redis.I started by transitioning a monorepo with 80+ microservices to a polyrepo setup, enhancing build times, code discoverability, and access control.I then developed an ELK-based logging pipeline to improve log access and troubleshooting in system. I created custom Logstash filters for our specific logging patterns and integrated Elasticsearch and Kibana for detailed log analysis.For DGOJ compliance in Spain, I designed a hybrid Go and Java solution to extract, consolidate, and report betting events via SOAP APIs, meeting strict regulatory requirements.In the "Odds Super Highway" project, I replaced REST with Kafka for interservice communication in our betting odds pipeline, enhancing reliability and preventing message loss. I also set up Kafka lag alerts and Horizontal Pod Autoscaling (HPA) to manage performance.In "Dynamic Translations," I re-architected the multilingual data system, centralizing Redis as the source of truth and using Kafka for versioned updates. Internal and negative caching reduced Redis lookups and improved performance.For a Japanese client, I optimized "livedoc," a WebSocket service, by moving it to Hong Kong to cut latency. A multi-region Kafka setup and eager-loading of translations addressed performance and cross-region Redis issues.Lastly, I developed an adapter service for integrating player prop betting markets, handling AMQP queue data, market lifecycles, and downstream updates with high reliability.
