Tiffany Marroquin is a Web Engineer based in New York with 10 years of experience building user-focused web products and leading small engineering teams. She has shipped customer-facing features and design systems across startups and enterprise retail (UNIQLO), improving engagement and reducing cart abandonment through data-informed UI work. As a technical cofounder at Upmarket she integrated complex third-party systems (Salesforce, HubSpot, Stripe) and cut onboarding from six months to one week, while orchestrating sprints and running user research with 70+ participants. Comfortable across modern front-end stacks (React, Redux, WebRTC, socket.io) and traditional stacks (WordPress, PHP, Sass), she balances rapid prototyping in Figma with disciplined delivery. Currently contributing at Fubo and freelancing, she combines product-minded engineering with hands-on implementation to accelerate team velocity. Collected analytics-driven wins and cross-functional leadership hint at a developer who treats UX metrics as a core part of engineering success.
