About Noam Or

Principal Data Engineer focused on building and designing AI, real-time, and large-scale data platforms in production. I am deeply hands-on, owning systems end to end—from architecture and core coding to deployment, optimization, and day-to-day operations.At Kajeet, I help power IoT connectivity and analytics platforms used by schools, healthcare providers, government organizations, and enterprise customers. My work spans real-time streaming, data platforms, optimization, and AI-assisted development, with a strong emphasis on scalability, reliability, and measurable business impact.What I do:* Design and build large-scale data platforms combining batch, streaming, and dimensional data models.* Build real-time and low-latency pipelines using Apache Flink, Kafka, NiFi, and AWS Kinesis.* Develop AI-powered systems for reconciliation, optimization, analytics, and decision support.* Write production-grade Python and Java code, including Python SDKs running directly on wireless routers (Cradlepoint) and integrating with cloud services.* Lead hands-on development of reconciliation and rate plan optimization systems, delivering significant cost savings and improved data integrity.* Use advanced AI prompting (Cursor, Codex, LLMs) to accelerate system design, code generation, refactoring, and production delivery across multiple platforms.Technical focus:* Languages: Python (expert), Java, SQL* AI & AI-Assisted Development: Advanced AI prompting, Cursor, Codex, LLM-assisted system and code design* Streaming & Analytics: Flink, Kafka, NiFi, Kinesis, Druid* Databases: PostgreSQL, Oracle, Redshift* Cloud & Infrastructure: AWS (Lambda, Glue, Kinesis, DynamoDB, SNS, SQS, SES, API Gateway, CDK), Docker* Data Modeling & BI: Dimensional modeling, star schemas, SCDs, TableauI am a builder by nature—equally comfortable designing systems and writing core code.
