HI THERE I’m Alexey Rirak

Upgrade Inc

• Developed reliable and scalable microservices for the investor platform, leveraging asynchronous event-driven communication with Kafka and deploying on AWS using Kubernetes
• Designed and implemented a report prioritization system for the investor report platform by allocating dedicated compute resources for the higher priority reports and parallelizing report execution. This boosted the system’s performance by over 55% and cut report generation time from hours to minutes
• Automated our system’s payment failure reconciliation procedure, transforming a 60-day manual process with multiple team hand-offs and Excel tracking, which used to require 10 people, into an efficient, automated solution that now requires just one person and completes within hours
• Reengineered the platform’s alerting process to rely on metrics and events instead of log scrapping, reducing false positives and missed alerts, and improving incident response time by 90%
• Participated in “on call” rotations to provide 24/7 production support coverage for my team’s systems, maintaining a 99.9% uptime SLO and resolving critical issues within an average response time of 30 minutes
