Dhruv Ahuja is a Lead Engineer at a managed hosting provider. He specializes in infrastructure solutions design and configuration, with a keen eye on achieving mechanical sympathy. His first brush with Puppet was in 2011 when he developed a solution on dynamically scaling compute nodes for a multi-purpose grid platform. He also holds a master's degree in Advanced Software Engineering from King's College London, and won the Red Hat UK Channel Consultant of the Year award in 2012 for delivering progressive solutions. A long history in conventional software development and traditional systems administration equip him with aptness in both areas, and he bridges many infrastructural gaps in a well-delimited way. In this era of infrastructure as code, he believes that declarative abstraction is essential for a maintainable systems life-cycle process.
