About

As an Staff Engineer at DP World, I lead and review the design and architecture of projects for end-to-end trace and track solutions for various logistics and transportation services, such as ocean, road, air, and parcels. I also contribute hands-on to the development of the maps and locations platform, which enables use cases like geofencing, port congestion, and notifications. I work with a tech stack that includes Java, NodeJs, Postgres, Redis, Azure, Crons, and Tile38. I have 12+ years of experience in developing microservices and scalable systems, with a focus on designing and building highly scalable, available, resilient, fault-tolerant, distributed, cloud, and on-premise systems. I have developed enterprise-class products that process millions of transactions per day with sub-second response. I have also developed reporting services using big data frameworks like Apache Spark, Kafka, NoSQL, etc. I own the product roadmap and backlog along with the product management team, and I have built a complete CI/CD pipeline from scratch for SaaS products. I have multiple certifications in software architecture, microservices, and RESTful APIs, and I have expertise in Java, Spring Boot, Reactor, Cassandra, Apache Kafka, Docker, Mesos, Jenkins, RxJava, GoLang, Python.
