About Mounika G

Hi there, I’m a Senior Java Full Stack Developer with 9+ years of experience building scalable, cloud-native systems using Java, Spring Boot, and modern frontend frameworks. I specialize in designing distributed, event-driven architectures and secure backend systems for enterprise applications across financial services, healthcare, and retail. I have hands-on experience building microservices-based platforms, real-time data pipelines, and high-availability systems on AWS and GCP. I also work on integrating AI and GenAI capabilities, including LLM-based workflows, Amazon Bedrock, and prompt engineering, to enhance data-driven applications and intelligent services. Core Expertise: • Backend: Java (8–21), Spring Boot, Spring Cloud, Hibernate, JPA • Microservices & APIs: REST, GraphQL, event-driven architecture, API design • Messaging & Caching: Kafka, RabbitMQ, Redis • Cloud: AWS, GCP • Databases: PostgreSQL, MySQL, Oracle, MongoDB, Cassandra • Frontend: React, Angular, Vue, TypeScript • DevOps: Docker, Kubernetes, CI/CD (Jenkins, GitLab), Terraform • AI & GenAI: Amazon Bedrock, LLM-based integrations, prompt engineering, AI-assisted development,ChatGPT, Claude, GitHub Copilot, Amazon Q • Programming: Java, Python, SQL Key Achievements: • Led modernization of legacy systems into microservices architectures • Designed and built event-driven systems handling high-throughput data processing • Delivered solutions across trading, healthcare analytics, and fraud detection domains • Implemented highly available, fault-tolerant distributed systems • Built and maintained automated CI/CD pipelines with zero-downtime deployments • Integrated ML and AI-driven components into production systemsI enjoy working on complex, large-scale systems that require strong architecture, performance optimization, and collaboration across teams. If you\'re hiring for backend or full stack roles focused on distributed systems, feel free to reach out or DM me here. Always open to discussing interesting engineering challenges.#OpenToWork #Java #FullStackDeveloper #Microservices #Cloud #AWS #SpringBoot #GenAI #AI
