Top SchoolTed Kaemming is a seasoned software engineer with 16 years building high-throughput backend systems and streaming pipelines for startups and scaleups across the San Francisco Bay Area. He has driven core infrastructure work at companies like Sentry, Parse.ly, PostHog, and now PlanetScale, specializing in reliable event ingestion, ClickHouse integrations, and Kafka client implementations. Ted combines deep systems-level coding—evidenced by his contributions to pykafka/samsa and Django subdomain tooling—with a pragmatic focus on data quality, resilience, and performance. As an early Sentry engineer he architected CDC and high-throughput replication tooling, and at Parse.ly he unified batch and streaming paths using Apache Arrow to cut serialization overhead. He mentors engineers, stabilizes legacy platforms, and prefers direct, technical conversations over startup outreach.
