What I'm looking for

I seek remote roles where I can build scalable backend systems, improve performance, mentor teams, and work with cloud, IoT, and blockchain technologies in an Agile environment.

I am a senior software engineer with strong expertise in Java (Spring Boot), cloud platforms (AWS, Azure), and backend systems for high‑scale web and IoT products. I have led features and small teams, delivered performance improvements (20% DB optimization), integrated blockchain for secure storage, and built resilient batch and real‑time pipelines for enterprise clients.

I thrive in remote, Agile environments and contribute to open‑source projects like ThingsBoard. I focus on clean code, maintainable architectures, CI/CD automation, and pragmatic solutions that improve reliability and user value.
