John has worked across consumer technology, banking, insurance, publishing, logistics, legal, education, and government, giving him a view of how architecture standards hold up under different regulatory and operational pressures. His technical scope spans public cloud platforms, DevSecOps and MLOps, Zero-Trust frameworks, and AI/ML deployment, supported by regulatory fluency in NIST, ISO, SOX, GDPR, and HIPAA.
His business acumen spans P&L ownership, M&A, and government contracting, giving him an uncommon ability to align technology decisions with the commercial models they support. That combination shapes how he approaches modernization work, where the harder question is often not which platform to adopt but what the organization can absorb, operate, and justify over time.
At Buchanan, John continues to advance platform engineering capabilities that give clients a clear, defensible path to modern cloud operations, and holds the engineers on his teams to current certification standards as a condition of the work.
