Lead Field Engineer Kestra

Accomplished Software and Solutions Engineering leader with extensive experience designing and delivering enterprise-grade data platforms for some of the world’s most demanding industries. As Lead Field Engineer at Kestra, Paul works with global organizations to unlock the power of open-source orchestration, helping teams unify complex workflows across data, AI, and cloud environments.

Paul’s career spans the full spectrum of the Software Development Lifecycle, from hands-on engineering to enterprise architecture. He is passionate about applying architectural best practices to build systems that balance speed, reliability, and scalability. His work consistently bridges the gap between cutting-edge open-source technologies and the practical realities faced by enterprises that need to deliver results at scale.

Prior to Kestra, Paul held senior technical roles at Aiven, KX, and FLYR, where he guided clients through challenges such as adopting cloud-native platforms, deploying Kubernetes at scale, and optimizing high-performance data systems. His experience has given him a unique perspective on how data platforms evolve, and why pragmatism often matters more than dogma.

Data and AI solutions promise transformational value, yet most initiatives fail to reach production or deliver results. Research shows that proof‑of‑concepts help organisations assess technical feasibility, verify market needs, understand limitations and make rational budget decisions. In AI projects specifically, PoCs allow teams to 'fail fast', identify challenges early, and minimise risks.

This talk will show how adopting a PoC‑to‑value approach can unlock benefits for both vendors and customers. It will demonstrate that tools must provide time‑to‑value quickly; nearly two‑thirds of users decide whether to keep a product during their first interaction, and users may take less than 40 seconds to decide. It will also highlight why change initiatives fail when end‑users are not engaged: 70 % of change programs fail due to employee resistance and lack of management support.
