Top SchoolJohn Horan is a Staff Software Engineer based in Ireland with 12 years of experience building full-stack Java systems and leading data engineering efforts. He has progressed from research-driven roles to technical leadership, architecting data pipelines and warehousing on AWS (ECS, Kinesis, Glue, EMR, Athena) and deploying Spark-based inference models to clean and analyze large datasets. At Zendesk he advances platform-scale features while earlier work at the Insight Centre combined forecasting, optimization and geospatial matching with Java, R and SQL to deliver production rostering and ride-matching solutions. A pragmatic engineer with a strong academic background (First Class honours, PhD study), he also contributes to open source at the kernel and audio-system level, having patches in the Linux kernel and PulseAudio—an uncommon crossover between cloud/data engineering and low-level systems work.
