Top SchoolJohn Topley is a Lead DevSecOps Engineer with over two decades in software development and more than a decade focused on cloud, DevOps and secure data platforms, currently designing the Integrated Data Service at the Office for National Statistics. He combines hands-on engineering—spanning Java, Ruby/Sinatra, Go and infrastructure as code—with team leadership and delivery of high-stakes public-sector projects such as national census systems that processed millions of page views with zero downtime. A pragmatic technical lead, he has architected secure random-code algorithms, automated full stack builds with Chef and Terraform, and migrated platforms between cloud providers while embracing open-source practices. Known for stepping into critical roles under pressure, he blends operational troubleshooting (including major site recoveries) with long-term architecture and automation to reduce risk and accelerate delivery. Based in the Greater Portsmouth area, he is a self-directed learner who continually adopts cloud-native and DevSecOps approaches to harden and scale data-driven services.
