Senior🎓
Top SchoolJohn Rafferty is a Senior Software Engineer with nine years of experience building backend systems and full-stack features across finance, food delivery, and healthcare domains. He is fluent in C# and RDBMS work, has recently expanded into Java/Kotlin with Cassandra, and regularly scripts ETL and data-processing pipelines using Python/PySpark. At Grubhub he automated partner onboarding with shared Lambda ingestion and documentation tooling, and at Q2 he re-architected ETL from USQL to a modern Azure/DataBricks stack while shipping real-time dashboards in .NET Core and React. Comfortable across cloud services, S3, Azure, and JVM ecosystems, he pairs deep backend reliability with practical front-end skills in React/Vue. Based in Belchertown, MA, he brings a pragmatic, operations-friendly approach—building tools that let non-engineering teams self-serve and reducing manual toil.
