With over 12 years of experience in software development, I am a senior software engineer who specializes in backend and full stack development with recent experience in data engineering, analytics, machine learning and AI. I have led and contributed to various projects involving backend REST API development, microservice architecture, data pipelines, databases, dashboards, and machine learning, using technologies such as Spring Boot, Kafka, React, AWS, Airflow, Neo4j, and Cassandra.My mission is to deliver customer value with a focus on quality by using test-driven development and data-driven strategies to build products that delight customers. I have a passion for solving complex problems with elegant and scalable solutions, and I enjoy collaborating with cross-functional teams and stakeholders to achieve the best outcomes. In my most recent role at Shippo, I prototyped new data pipelines and dashboards to aggregate and visualize customer shipping data.
