Description

Java Backend Developer with 6 years of experience building and operating high-traffic, production-grade systems across fintech, transportation, and online platforms.

Strong background in Java and Spring ecosystems, with hands-on experience designing REST APIs, event-driven architectures (Kafka), and microservices running in containerized environments (Docker, Kubernetes on GCP).

Experience includes developing backend systems from scratch, optimizing performance in high-load environments, and modernizing legacy systems (including Java EE and COBOL integrations) while ensuring business continuity.

Currently working on a multinational, high-availability platform, focusing on scalability, fault tolerance, and system reliability.

Comfortable owning backend systems end-to-end — from design and implementation to monitoring and continuous improvement — with emphasis on clean architecture, observability (Elastic, Grafana), and maintainability.
