What You'll Do

• Create interactive visualizations in AG Charts and/or integrate with complementary charting libs as needed.
• Use Framer Motion or GSAP to add purposeful micro- interactions and page transitions (accessibility- and performance- aware).

• Write robust tests (Jest, React Testing Library, Cypress) and maintain clean, typed code with ESLint/Prettier.
• Partner closely with designers and PMs; participate in code reviews and mentor engineers.
