  • Architected and developed the new balance management microservices, developing a more performant and scalable system. Leveraged technologies like Kafka, Kotlin, Java, Oracle and Kubernetes to design a system prepared for sharding. Achieved an infrastructure cost reduction of thousands of dollars while maintaining an excellent performance, with REST APIs handling up to 250,000 requests per minute, 99% of which received a response in under 50ms. Processed approximately 98% of events in under 5ms.
  • Helped different engineering teams with their integration with the new microservices.
  • Worked closely with product managers and different areas of the company to plan the roadmap for future features and improvements in our domain.
  • Was on the on-call rotation helping solve incidents in production, writing automated alerts and dashboards with Grafana/New Relic and using New Relic APM and Jaeger to analyze performance bottlenecks.
  • Participated in the hiring process by conducting technical interviews for engineering roles across various levels.
  • Created a tech guild in the team to help onboard new team members, consolidate the knowledge of our tools and services and share new ideas.
