About Prakash Kumar Singh

I am a Software Engineer with 5+ years of experience in building scalable enterprise applications and high-performance backend systems. My primary expertise lies in Java, Spring Boot, Microservices, and System Design, where I have consistently delivered solutions that improve performance, reliability, and scalability.I specialize in designing REST APIs, event-driven systems (Kafka, RabbitMQ), caching strategies (Redis), and database optimization (PostgreSQL/MySQL, JPA/Hibernate). I have hands-on experience with Spring Cloud (Eureka, Config Server, API Gateway), security (Spring Security, JWT, OAuth2), and observability (Prometheus, Grafana, ELK, Spring Actuator). My work often involves deploying containerized services using Docker & Kubernetes, with CI/CD automation via Jenkins and GitHub Actions.In addition to core backend engineering, I have worked extensively on AI integration—building RAG (Retrieval Augmented Generation) pipelines with Qdrant, LangChain, and OpenAI APIs, and developing intelligent chatbots that enhance enterprise workflows. Earlier in my career, I contributed to Salesforce full-stack development, including LWC migration, metadata-driven frameworks, and AppExchange package development.I am passionate about solving complex problems, driving system design discussions, and mentoring engineers on clean code, design patterns, and scalable architecture. Currently, I am seeking opportunities where I can apply my backend expertise in Java/Spring Boot while contributing to AI-driven, cloud-native, and large-scale systems.
