Why this is senior work
I design systems that other developers can build on. This architecture solved a company-wide problem: giving every new application the same structure, conventions, and predictable way to talk to its API.
Key contributions
What I built
Frontend architecture
Designed the frontend structure, application templates, reusable patterns, component organization, and development conventions.
API architecture
Worked on API patterns and client-server contracts to establish consistent communication between frontend applications and backend services.
Client-server contracts
Defined and implemented patterns that made frontend/API integration more consistent and predictable across applications.
Authentication
Implemented multi-session authentication using secure cookies.
Reusability
Built the architecture as a reusable foundation for multiple applications rather than a single project's solution.
Company-wide adoption
The architecture and templates were used across the company.
