Jennifer Louise Lynch

Software Engineer

Frontend specialized Software Engineer with 7+ years in React and TypeScript, with growing full-stack capabilities. I work at the intersection of design, product, and engineering. Building polished, practical interfaces with end-to-end ownership from concept to production. Comfortable across the stack, collaborating with backend teams to optimize data flows, API design, and processing efficiency. Passionate about working closely with UX and product to build the right solutions. Recently took a career break to travel and deepen full-stack skills through projects involving PostgreSQL, REST APIs, and AI integration. Seeking a product-focused team where quality and user impact drive decisions.
