What I'm looking for

I seek engineering roles where I can lead architecture and modernization efforts, work on scalable microservices, and mentor teams in an Agile, DevOps-focused environment.

I am a Senior Software Engineer with over 12 years of experience building scalable Java/JEE and Node.js systems, modernizing legacy platforms into microservices, and delivering real-time web interfaces using React, Vue.js and Angular. I have deep expertise in search technologies (Lucene, Solr, Elasticsearch) and have led technical teams to produce production-grade services in finance and trading domains.

My work focuses on architecture, performance optimization, and reliable deployments using Docker, Kubernetes/OpenShift and CI/CD. I drive integrations with core banking and custody systems, design event-driven pipelines with Kafka and MQ, and mentor engineers while enforcing TDD/Agile practices to deliver measurable business value.
