Profile bio

About Ms. Ruby

I’m Ruby, a Java Full Stack Developer for creating high-performance, scalable, and secure software solutions. With a Master’s in Computer Science and Bachelors in Computer Science and hands-on experience at companies like American Express, I’ve honed my skills in Java, Spring Boot, microservices, and cloud technologies like AWS and Kubernetes • Cutting Transaction Latency by 20%: At American Express, I worked on enhancing our digital payments platform. By re-architecting the backend with Spring Boot microservices, integrating MongoDB, and implementing real-time processing with Apache Kafka, I optimized our APIs and slashed transaction times. This meant faster, more reliable payments for millions of users—no more waiting around! • Boosting Uptime with Microservices & Cloud Solutions: I worked on making systems run smoother. I containerized our applications with Docker and deployed them on AWS using Kubernetes, which allowed us to scale effortlessly while maintaining high availability with real-time monitoring through Prometheus, resulting more resilient, reliable system with significantly improved uptime.• Enhanced Data Processing Efficiency by 30%: While working on a transaction processing system, I integrated Apache Spark with our data pipelines, streamlining ETL processes from Cassandra and Couchbase databases. This optimization significantly improved the speed and accuracy of data analysis tasks, supporting faster business decisions. • Reduced API Response Times by 40%: By implementing best practices in API design, including optimizing endpoints, using caching strategies with Redis, I was able to significantly reduce response times, improving overall user experience and system reliability. • Backend: Java, Spring Boot, Vert.x, Core Java, Spring MVC, Servlets, Hibernate, JDBC, JMS, Kotlin • Frontend: ReactJS, Angular, JavaScript, HTML/CSS, TypeScript, jQuery, AJAX • Databases: MongoDB, MySQL, PostgreSQL, Redis, Cassandra, OracleDB, Couchbase • Cloud & DevOps: AWS (ECS, EKS, Lambda, CloudWatch), Docker, Kubernetes, Jenkins, Azure DevOps, Git, Bitbucket, GitHub • Data Streaming & Processing: Apache Kafka, Apache Spark, Hadoop, ETL Pipelines • Security & Monitoring: Prometheus, SonarQube, Splunk, PCI DSS compliance, Hystrix for circuit breakingLet’s connect if you want to chat tech, solve problems, or share memes, I’m always up for a good conversation about making things better!
