In conclusion, a senior frontend engineer is expected to possess a comprehensive set of technical skills, demonstrate leadership qualities, and shoulder responsibilities that contribute to the success of frontend projects. By combining their technical expertise with effective communication, collaboration, and a continuous learning mindset, senior frontend engineers can drive innovation, mentor junior team members, and elevate the quality of frontend development within their organizations.

How I led the frontend development of a FinTech company

I led the frontend development of a customer-facing and merchant-facing e-commerce/FinTech solution which facilitated synchronized sales data across multiple channels (e.g. Woo-Commerce and Point of Sale (P.O.S) outlets in multiple locations) with internal tools for administrative management e.g. handling Know Your Customer (K.Y.C) processes.
