About

Backend Engineer with 4+ years of experience building scalable distributed systems using Java and Spring Boot.I specialize in designing microservices and event-driven architectures that handle high-volume backend workflows. My experience includes building RESTful APIs, asynchronous processing pipelines, and optimizing system performance using caching, indexing, and efficient database design.Technologies I work with regularly:• Java, Spring Boot, Spring Security • Microservices & Distributed Systems • Kafka, AWS SQS/SNS (event-driven architectures) • Redis caching & performance optimization • MongoDB, MySQL, PostgreSQL • Docker, Kubernetes, AWSAt Pristyn Care, I have worked on large-scale backend systems including insurance automation platforms, AI-driven settlement processing, and internal CRM systems that replaced Salesforce and reduced operational costs.I enjoy solving complex backend problems, improving system performance, and designing scalable architectures.Currently open to opportunities where I can contribute to building reliable high-scale backend systems.Feel free to connect or reach out.
