* Mentoring and providing hands-on guidance to junior developers and cross-functional colleagues, fostering a culture of collaboration, code quality, and continuous improvement.
* Translating the product vision and strategic goals into clear, actionable technical tasks and sprint deliverables in partnership with the Product Manager.
* Staying abreast of emerging trends and innovations, including AI-based enhancements, to continuously evolve the platform and user experience.
