I'm building ForteBank's Request to Pay system with VISA, delivering secure real-time payment request exchanges, lifecycle tracking, and user notifications across partner banks.
At Kaspi.kz, I developed and tested search microservices serving over 100K daily requests, reducing response time from 400 ms to 100 ms and improving search accuracy by 7%. I also independently launched Kafka-based microservices that generated more than USD 1M in cost savings and built tariff-plan functionality that saved over USD 500K.
I've worked across Java, Spring Boot, Kafka, PostgreSQL, Redis, Kubernetes, and observability tooling, including production-like load-testing environments and high-traffic Spring Boot upgrades handling 8,000+ requests per minute.
