Senior🎓
Top SchoolLawrence Carvalho is a seasoned full stack engineer and engineering manager with 17 years’ experience delivering customer-facing web platforms and scalable APIs across retail, media, and consumer products. He blends hands-on architecture and implementation with people-first leadership, having grown engineers from junior to staff and led cross-functional teams at organisations like Peloton, Marks & Spencer and LSEG. Notable outcomes include driving ~£10M incremental revenue through data-driven experiments, reducing CAC by 40% through tooling, and shipping content platforms that served hundreds of thousands of pages and the majority of organic traffic. He’s pragmatic about trade-offs—introducing ADRs, C4 modelling and Wardley Maps to align technical decisions with business strategy—and comfortable owning migrations and performance-sensitive personalisation work. Based in Stony Stratford, he combines deep frontend and backend expertise with a knack for developer experience improvements that measurably reduce build failures and increase velocity. He remains active in mentoring, community outreach and advising newcomers to the industry.
