1. Frontend Development

I specialize in building modern, responsive web interfaces using Angular and React. My frontend work emphasizes clean design, mobile responsiveness, and accessibility. I work with TypeScript, HTML5, and CSS3, and often use component libraries like PrimeNG and PrimeReact to accelerate development while maintaining design consistency.

2. Backend Development

On the server side, I use C# with .NET 7/8 to build secure, scalable, and maintainable APIs. I follow RESTful architecture principles and implement authentication and authorization using JWT. My backend focus is on clean structure, performance, and smooth integration with frontend applications.

3. Database Design & Management

I use SQL Server to design and manage relational databases, following a DB First approach. My experience includes creating optimized schemas, writing efficient queries, and handling real-time data operations. I ensure that data flows smoothly between the frontend, backend, and the database.

4. Tools & Workflow

My development workflow includes Git and GitHub for version control, Visual Studio and VS Code as IDEs, and tools like Postman and Swagger for testing and documenting APIs. I work with JSON for data handling and manage environment-specific configurations for flexible deployments. I'm experienced with hosting on IIS and deploying assets via S3 and CloudFront.

5. Custom Solutions & Features

Beyond core development, I build custom solutions tailored to client needs — from admin dashboards and contact forms to donation systems and newsletter integration. I’ve also implemented features like PDF generation, digital flipbooks, advanced filtering tools, and user-friendly content management systems.

6. What I Offer

I’m available for freelance work, part-time collaboration, or full-time roles. Whether you need a reliable developer to build a full-stack solution or help bring a specific feature to life, I bring clean code, a user-focused mindset, and a strong commitment to solving real problems through thoughtful development.
