Summary
👤
Senior🎓
Top SchoolPhil Kallos is a seasoned engineering leader and CTO with 11 years of experience building data-driven systems and teams from the ground up. Based in San Francisco, he co-founded Neon Redwood after leading data science and engineering at Foresite and establishing ShopStyle’s large-scale data pipeline using Kinesis, Hadoop, and Spark. He has a track record of translating product needs into measurable results—once driving a 40% jump in engagement through front-end re-architecture—and of operationally improving delivery (e.g., cutting deploy times dramatically and moving teams to continuous deployment). A hands-on architect who blends infrastructure, data, and product sensibilities, he favors pragmatic experimentation and has repeatedly built in-house tooling and A/B frameworks to close the loop between engineering and user impact.
