Jonathan Kempf is a Tech Manager with 11 years of experience turning early-stage startup visions and complex design problems into high-performing consumer products. He blends hands-on front-end craft—React/Next.js, performance tuning, and accessibility—with proven people leadership, having doubled engineering teams and scaled roadmaps into shovel-ready backlogs. Jonathan has repeatedly driven measurable business impact: boosting conversion and traffic, slashing image payloads with a serverless image service, and raising accessibility scores from 15% to 95%. He excels at translating executive strategy into clear sprint plans and engineering practices that multiply velocity while reducing technical debt. Based in Niagara Falls, NY, he brings a user-obsessed mindset (“Pro lector! — For the users!”) that marries delightful UX with pragmatic delivery. Colleagues describe him as a builder who treats product design and engineering as a single craft, not two separate disciplines.
