What You'll Be Doing You will be instrumental in the development of the frontend for our cutting edge Kolleno product, encompassing the design, structural layout, and execution of HTTP calls to APIs developed by our skilled backend team. Your code will serve as a crucial component in driving the growth of the company, necessitating a collaborative approach with various departments. You will work in tandem with the founders, data science, backend, sales, marketing, and account management teams to ensure the final product aligns with our company's strategic objectives.
