Мои компетенции и опыт

Senior Software Engineer with almost six years of backend Java experience in designing and shipping microservices and developer libraries end-to-end, while mentoring and strengthening engineering team.

Currently drives feature work on Axon-based CQRS service backed by Cassandra for product and quota management; authors a modular Condition Engine for type-safe business-rule enforcement; and created a custom RSQL-style query language parser that compiles high-level filters into efficient JOOQ (PostgreSQL) and Elasticsearch requests.

Previously engineered a reactive Quarkus survey-scripting service at scale on Cassandra, delivered a Redis-powered configuration microservice in Go, and built a dashboard service with full RBAC—all within a microservice ecosystem.

Early-career highlights include an internal Spring Boot / PostgreSQL / Kafka / Elasticsearch ticketing platform with S3 file handling, a reusable generic JOOQ repository, and a zero-downtime bulk-reindex pipeline.

Core stack: Java 17/21 (Spring Boot), PostgreSQL + JOOQ, Cassandra, Redis, Apache Kafka, Elasticsearch, Docker, Kubernetes, Prometheus/Grafana.
