Summary

As a CRO Specialist and Front-End Developer at British Gas, I apply both technical expertise and creative insights to design, implement, and manage A/B and multivariate testing strategies using Adobe Target. With a focus on optimising user experiences, I leverage test outcomes and business insights to continuously enhance the digital journey for the UK’s largest energy and home services provider.

In my current role, I write robust, clean, and well-documented code to bring the visual elements of tests to life within Adobe Target, ensuring cross-browser and cross-device compatibility. I collaborate closely with cross-functional teams, including UX/UI designers, product managers, and data analysts, to develop testing strategies aligned with business goals. Additionally, I provide mentorship and technical guidance to junior developers, while staying abreast of industry trends and advancements in testing technologies.

I am also responsible for interpreting test data and generating comprehensive reports, transforming complex insights into actionable, data-driven recommendations for stakeholders. Effective communication is key, and I ensure that testing plans, progress, and results are clearly conveyed to both technical and non-technical stakeholders.

Prior to British Gas, I worked as a CRO Developer and Front End Developer at Next, where I was instrumental in driving a £25 million uplift through A/B testing. I also founded Monocode, a digital agency that blends creative and technical expertise to optimise client websites and strengthen brand presence. With a BA (Hons) in Fine Art from De Montfort University, I am passionate about delivering engaging, innovative digital experiences that drive measurable results.
