Andrew is the founder and CEO of PX Systems, his second startup. He co-founded his first, Parse.ly, and served as its CTO for twelve years. Parse.ly grew to 500+ enterprise customers, raised $12M in venture capital, and was acquired by the company behind the world's most widely deployed web stack in their “largest acquisition by cost and revenue.” Andrew hired every member of Parse.ly’s fully distributed product team. That team of 30 world-class frontend and backend engineers built an industry-leading real-time content analytics product, running on petabyte-scale data infrastructure and trusted by Bloomberg, the NFL, NBC, the WSJ, and many other major media companies and Fortune 500 brands.

A big part of his past work was making Python practical for large-scale distributed data processing. This included shipping open source software to scale Python up atop massive cloud clusters in AWS, using streaming data from high-throughput Kafka topics. His team's work included various technical feats. Once, they wrote the first high-performance Python driver for Kafka using native C code in the critical path, and released it as open source. Another time, they adapted a Clojure-based distributed cluster computing framework to Python, and released that as open source.

Andrew contributed to the ecosystem for distributed cloud systems and fully distributed teams. He spoke about his work at PyCon US, CTO Summit NYC, PyData Silicon Valley, O’Reilly Strata, and PyData NYC.

After his first startup’s acquisition, Andrew spent two years as Head of Product and Engineering for the acquirer’s enterprise software group. There, he saw backend teams keep hitting the same roadblocks his own team had hit, both inside the company (more than 50 distinct engineering teams) and across its 700+ customer deployments.

Andrew has stayed hands-on throughout his career. He holds a computer science degree from NYU. He is an alum of the Recurse Center in NYC. He has built scaled production systems in Python, JavaScript, and C. He believes that behind every great product is a creative environment of talented designers and engineers. This leads not only to great software, but also to a mastery of craft and a culture of innovation. At PX, he’s going after the root of a problem he’s watched teams struggle with for years: making it easy for backend programmers to rapidly ship scalable systems on the cloud.
