James Whitfield

“ James Whitfield is a two-time startup founder and CTO based in London with 11 years of experience building engineering teams and making infrastructure decisions that define a company's runway. His first company burned through Heroku bills that reached £3,200 a month before the team finally migrated, too late and too painful. His second company started leaner, made smarter platform choices from day one, and scaled to Series A without a dedicated DevOps hire. James has led engineering teams of up to 22 people, architected SaaS products across AWS and GCP, and spent years helping other early-stage founders avoid the infrastructure mistakes he made the first time around. He has a specific eye for where cloud costs hide in compute idle time, database tiers, egress fees, and per-seat pricing models that punish growth. At Kuberns, James writes about infrastructure decisions for founders and CTOs, how to think about platform choice, when managed PaaS makes sense over raw cloud, and what early-stage teams should be spending on infrastructure versus product. ”
