About

As a Staff Solution Engineer at Stack Overflow, I support global Enterprise & Strategic accounts, driving the adoption and value realisation of the Stack Overflow for Teams platform. I specialise in designing and executing Change Management programs to scale Knowledge Communities, significantly improving Developer & Software Engineering productivity and satisfaction by leveraging a blend of technical expertise, process optimisation, and people-centric strategies. My work also involves close cross-functional collaboration to redesign the platform and ensure optimal product-market fit. My recent experience at Stack Overflow also includes applying comprehensive knowledge of the generative AI landscape to support organisations in building and training LLMs, AI Agents, and RAG applications. I help clients evaluate data samples for LLM pre-training, providing data-driven recommendations to ensure successful evaluation runs and efficient, secure data access, directly contributing to new data acquisition and company revenue. I also work alongside the technology teams of large enterprise organisations to set up and optimise their software developer focussed AI Agents. Previously, as a Solution Engineer at Tableau (acquired by Salesforce), I led strategic pre-sales initiatives and technical enablement across EMEA, playing a key role in driving data democratization and adoption. My foundation includes strong statistical analysis and data manipulation skills from my time at Urban Science. I am passionate about translating complex technical solutions into clear business value, fostering community, and driving innovation in dynamic environments. Open to connecting with leaders in SaaS, AI, and enterprise technology.
