What I'm looking for

I seek a role building scalable backend systems and integrations, with opportunities to lead technical projects, mentor teams, and deliver measurable performance and reliability improvements.

I am a Senior Java Developer with extensive experience building scalable backend systems, integrating document-processing APIs, and delivering enterprise consulting solutions. At Aspose I led Java-based development, implemented Spring Boot microservices, and deployed over 20 new features while reducing deployment time and bug resolution.

I design and optimize event-driven architectures using Apache Kafka and Redis, implement RESTful APIs, and improve frontend experiences with Angular and RxJS. My career includes building high-availability services for large user bases and modernizing web applications to improve performance and user engagement.

I bring a results-driven engineering mindset, strong debugging and automation practices, and hands-on leadership in delivering custom client solutions and cross-functional projects. I seek opportunities to build reliable, high-performance systems and mentor teams toward measurable impact.
