Analytics Lead @ British Gas
Nov 28, 2024, Monika Managed Lloyd directly
Lloyd joined the business at the beginning of September 2024 and ever since has shown a great work ethic, delivery at a very high standard and the ability to work autonomously.Â
Immediately he managed to fit well within the team as well as the wider function. He has grasped Adobe Target very quickly and managed to deliver on numerous AB tests since joining. All of the output was thoroughly checked by him and there were no errors.
His approach to work is very professional - always meeting deadlines, working above and beyond in occasions where we have tight timescales.
Lloyds front end dev skills are outstanding and he has received flawing feedback from various stakeholders within the business.

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.
