Summary

Senior🎓
Top SchoolJohn Wards is a senior engineering leader with 15 years’ experience scaling teams and rebuilding platforms, currently serving as Head of Engineering in London. He has grown organisations from small startups to 80+ engineers, led migrations of over a million subscribers, and launched products that increased contract value tenfold. Technically fluent across cloud-native architectures, data infrastructure, and full-stack development, he combines hands-on contributions to prominent open-source Symfony projects with strategic delivery at enterprise scale. His background includes building embedded analytics and retail media platforms, cutting AWS costs by half, and shifting teams to full-stack ownership to boost speed and accountability. Comfortable in CEO-level conversations and technical due diligence, he excels at translating business goals into architecture and team structures that sustain rapid growth. A lesser-known thread through his career is sustained low-level code craft—bug fixes and refactors in core framework components—showing he still dives into the code when it matters.
