I'm a Senior Software Engineer with 15+ years of experience building scalable backend systems using Node.js, Java, and modern web technologies. Recently I’ve focused on AI-powered applications, including LLM-based solutions, intelligent automation, and retrieval-augmented generation pipelines. I’ve built real-world systems such as internal assistants, customer-support automation, and knowledge-driven tools by integrating LLM APIs into production environments. I design modular, production-grade architectures that combine APIs, databases, and event-driven workflows to support multi-step processes and real-time interactions. I thrive in cloud-native environments (AWS, Docker, Kubernetes) and have delivered across Energy, Startups, and Financial Services, including payments integration and secure transactions.…I'm a Senior Software Engineer with 15+ years of experience building scalable backend systems using Node.js, Java, and modern web technologies.
