What I'm looking for

I'm ready to pursue new opportunities building high-quality, scalable enterprise software, defining well-designed architecture, and collaborating with cross-functional international teams.

At Energize Global Services for Worldline, I develop and optimize Java/JavaEE FinTech products for batch transaction processing at European banks, resolving 30+ security vulnerabilities and 100+ performance issues. I work across distributed teams in France, Germany, Belgium, and the Caucasus region.

I've built high-throughput services for Café Bazaar, processed up to 2 million Kafka events daily at Tapsell, and delivered a Spring Boot payments backend serving 100,000+ active clients at Jiring. My work spans Java, Kotlin, microservices, Kubernetes, cloud platforms, architecture, DevOps, and reliable production infrastructure.
