AB WHITTINGTON

Behind the open-source tools and the products is a long run of platform engineering and leadership in reliability-sensitive domains — e-commerce, healthcare, and payments. This is where the engineering judgment comes from.

The work was rarely greenfield. It was modernization, migration, and scaling done while the business kept running — the hard version of the job.

• Scaled engineering organizations from 5 to 50+ engineers at enterprise platforms including Carvana.
• Led AI integration at scale, serving millions of customers in customer care and operations at a major online auto retailer.
• Built and ran a 48-person offshore engineering division for a healthcare SaaS platform (Salucro, now U.S. Bank).
• Owned platform architecture for e-commerce, healthcare, and enterprise systems processing millions in transactions.

• Modernizing legacy systems without pausing the business. Incremental migration under live load, not a big-bang rewrite.
• Reliability in healthcare logistics and payments. Domains where an outage is not just an inconvenience.
• Cost control during cloud migration. Moving fast without letting the bill run away.
• Design systems and internal tooling that outlive any single team or reorg.

• 28 years of hands-on engineering and leadership.
• Teams led up to 48 engineers across onshore and offshore.
• Migrations, cost work, design systems, and internal tooling — the track record that 11 Mile Co is built on.
