This repository demonstrates my full-stack development skills with React/TypeScript on the frontend and C#/ASP.NET Core + SQL on the backend, showcasing scalable solutions, algorithm practice, and real technical assessments for interview preparation.
- React + TypeScript - Component development and UI logic
- Vite - Build tooling
- React Testing Library / Vitest - Testing
- TypeScript - All algorithm practice (LeetCode-style problems, data structures, interview patterns)
- Jest / Vitest - Unit testing
- Focus: Arrays, strings, hash maps, recursion, two pointers, sliding window, functional programming
- ASP.NET Core Web API - RESTful services
- Entity Framework Core - ORM
- SQL Server - Database
- xUnit / NUnit - Testing

- State management patterns
- API integration and async operations
- Performance optimization
- Real technical assessments
All algorithm exercises are implemented in TypeScript
Common interview patterns including:
- Array manipulation (two pointers, sliding window)
- String algorithms
- Hash maps and sets
- Recursion and dynamic programming
- Tree and graph traversal
- Time & space complexity analysis
- RESTful API design
- CRUD operations with Entity Framework
- Authentication & authorization (JWT)
- Database design and SQL optimization
- Integration testing
- Complete end-to-end solutions
- Architecture decision documentation
- Performance analysis
- Real interview feedback (when available)

All solutions include:
For Algorithms (TypeScript):
Time: O(n log n) - sorting dominates
Space: O(n) - hash map storage
Trade-offs: Why this approach was chosen
For React Projects:
Rendering Performance: O(n) - list rendering
State Updates: O(1) - direct state access
Bundle Size: ~145KB (production build)
For Full-Stack Assessments:
API Response Time: ~50ms (average)
Database Queries: Optimized with indexes
Frontend Bundle: 245KB gzipped
Lighthouse Score: 95+ (Performance)
- React: 80%+ component coverage with React Testing Library
- TypeScript Algorithms: Unit tests for all public functions
- C# Backend: Integration tests for API endpoints + unit tests

Full-Stack Developer with expertise in React + TypeScript for modern frontend development and C#/ASP.NET Core for scalable backend systems. All algorithm practice is implemented in TypeScript to strengthen JavaScript/TypeScript interview skills while maintaining backend proficiency with .NET.
✅ Frontend-first approach with React + TypeScript
✅ All algorithms in TypeScript (not mixed with C#)
✅ Backend expertise with C#/ASP.NET Core
✅ Real technical assessments from actual interviews
✅ Full-stack thinking across the entire development cycle
Solutions prioritize clarity and learning over premature optimization, with focus on:
- Clean, testable code
- Proper separation of concerns
- Industry best practices
- Interview-ready explanations
