With close to 10 years of experience in JVM-based technologies, I specialise in designing and developing distributed systems that handle large-scale data. I am proficient in methodologies such as microservices architecture, event-driven systems, cloud-native applications, domain-driven design, infrastructure as code, and CI/CD. I have hands-on experience in object-oriented programming (OOP), functional programming (FP), and reactive programming for designing and developing production systems. With over 6 years of experience working with Scala, I have implemented scalable solutions and mentored others in Scala development. I also have extensive experience with Java and Spring Boot, as well as working with NoSQL databases, including MongoDB. Additionally, I have practical experience building data pipelines using Spark, Apache Kafka and working with processing frameworks like MapReduce and Cascading.I have deep expertise in extreme programming (XP) practices, including test-driven development (TDD), pair programming, CI/CD, small releases, and refactoring. I advocate for XP practices to facilitate smooth implementation and effective collaboration across cross-functional teams, ensuring high-quality outcomes that deliver business value.I have experience implementing microservices-based, event-driven reactive systems from the ground up. I have been involved in all stages of product development, from requirements gathering, estimation, and sprint planning, to story writing, development, testing, and product release. My focus is on aligning technology with business needs to achieve pragmatic, business-driven goals rather than purely technological ones.
