Context

DotOne Gold is a high-traffic FinTech platform where users trade digital gold securely. My role focused on building a resilient frontend architecture that handles complex asynchronous financial workflows, token lifecycles, and strict validation securely.

Engineering priorities

  • 01Complex API interactions with strict security and automatic JWT refresh lifecycles without dropping requests.
  • 02Critical financial forms requiring rigorous client-side validation using Zod and React Hook Form.
  • 03Real-time state synchronization for user balances and market prices across the application.
  • 04Cross-device precision from complex Figma designs while maintaining strict JS bundle-size budgets.

Implementation focus

01

Built Next.js and TypeScript interfaces from detailed product designs.

02

Developed API and server-state handling with Axios and React Query, including token refresh and controlled retry behavior.

03

Implemented financial forms and state flows with React Hook Form, Zod, and Zustand.

My role

As Senior Frontend Developer, I own frontend architecture and implementation for assigned product areas, investigate production UI issues, and work with stakeholders on quality and delivery.

What the work delivered

  • More predictable API and authentication behavior across frontend workflows.
  • Financial forms with clearer validation and recovery paths.
  • A maintainable feature-oriented frontend that supports ongoing product delivery.
