Hire the Best Java Developers
in Armenia

As a Senior Java/AI Engineer with over 12 years of experience, I specialize in building scalable, secure, and high-performance systems using Java, Spring Boot, and Spring Security. My background spans across microservices, event-driven, and service-oriented architectures, enabling me to deliver robust, maintainable backend solutions. I have deep expertise in Kafka, RabbitMQ, and RESTful API design, combined with hands-on experience integrating AI-driven and data-centric technologies like LangChain, LangFlow, Qdrant, and OpenAI APIs — bridging traditional backend systems with modern LLM-powered workflows. I’m passionate about system design, clean architecture, and test-driven development, and thrive in Agile teams where collaboration and innovation are key. My focus is on crafting elegant, future-ready solutions that accelerate business value and enhance user experience. Driven by curiosity and continuous learning, I’m always exploring emerging technologies in AI, distributed computing, and knowledge retrieval, and applying them to create intelligent, scalable Java ecosystems.
