Compical turns one ambiguous operating problem into evidence leadership can use to proceed, revise, defer, or stop. John leads the work from the fit call through the executive recommendation.
John has 15 years of product and engineering experience. At Apple, he worked on software that coordinated datacenter systems. He later served as a Staff Software Engineer at Chime, where he worked on MyPay from early development through launch. MyPay lets eligible members access part of their pay before payday. Chime reported that MyPay reached more than $400 million in annualized revenue in Q4 2025.
John began studying machine learning in 2013 and has continued building with machine-learning and generative-AI tools. That experience informs the work, but each recommendation rests on evidence from the business’s own workflow, systems, and controls.
John starts with the current process and the decision leadership needs to make. He checks the economics, existing software, data access, failure modes, and human-review requirements before recommending new technology. The business’s domain, process, finance, and IT or security owners keep their decision authority throughout the engagement.
Compical is based in the San Francisco Bay Area. John works remotely with firms across the United States and is available for on-site work throughout the country.
