After transitioning from my previous full stack role, I've shifted my focus to frontend development, contributing to a large-scale rewrite of our core platform into a modular super app designed for scalability and flexibility.
My key contributions include:
- Architecting and develop a modular frontend architecture, enabling independent deployment and maintenance of platform features.
- Implementing responsive and accessible UI components based on detailed Figma designs provided by the design team.
- Coordinating with backend engineers, product managers, and designers to ensure alignment on technical specifications, usability, and delivery timelines.
- Supporting the refinement and application of our internal design system, promoting UI consistency across modules including (but not limited to) Nuxt Layers, State Management, strict type checking, etc.
This position builds on my previous full stack experience and allows me to apply my broader product understanding to create better-aligned and more efficient frontend solutions using Nuxt 3, TypeScript, and modern web practices.
