About

Professional summary

I am a Solutions Architect and software engineer with experience building high-volume fintech platforms and microservice-based systems.

I design scalable, secure architectures for payment and search products, with a focus on event-driven systems, API integration, data consistency, and operational reliability.

I have worked with Java, Go, Apache Kafka, PostgreSQL, Redis, Kubernetes, Spring Boot, and cloud-native engineering practices. My experience includes architecture reviews, requirements gathering, technical documentation, and end-to-end delivery.

At Kaspi.kz, I developed and launched systems serving more than 100,000 daily requests and helped deliver substantial cost savings through optimized microservices, search, and tariff-plan capabilities.

I am comfortable improving production performance, modernizing high-traffic services, creating pre-production environments, and implementing observability through Grafana and Prometheus.

I hold a Bachelor of Science in Computer Science from Nazarbayev University and bring a strong foundation in algorithms, distributed systems, databases, networking, and software design.

Experience

Career history

Solutions Architect ForteBank

Designed the architecture for a Request to Pay (R2P) microservices system in collaboration with the VISA payment network. The platform enabled secure real-time payment-request exchanges with partner banks, full lifecycle status tracking, and user notifications.

Integrated Grafana metrics and Prometheus monitoring for deserialized Apache Kafka messages across multiple services, improving error handling and operational visibility. Worked with gRPC, PlantUML, PostgreSQL, Redis, Apache Kafka, Go, Git-based CI/CD, and API gateways.

Software Engineer Kaspi.kz

Developed and fully tested a search-engine microservices system handling more than 100,000 requests per day. Gathered functional and non-functional requirements, conducted architecture review sessions, documented technical decisions, improved response time from 400 ms to 100 ms, and increased search-result accuracy by 7%.

Independently designed and launched Kafka-based microservices using PostgreSQL, Redis, Oracle GoldenGate, and XML/JSON serialization, contributing to more than USD 1 million in cost savings for over 100,000 daily active users. Built tariff-plan functionality using SOAP and REST APIs and designed indexed relational database structures, generating more than USD 500,000 in savings.

Created a containerized pre-production environment using Kubernetes and Helm for end-to-end load testing and infrastructure validation. Upgraded high-traffic Spring Boot microservices from version 2.7 to 3.0 while supporting more than 8,000 requests per minute.
