SaaS & Web Application Development

I specialize in ASP.NET Core for building robust backend systems, combining RESTful APIs, microservices architecture, and modern authentication patterns. The frontend leverages Blazor for C#-based SPAs, React for complex UIs, or traditional MVC patterns depending on project requirements.

This full-stack approach ensures seamless integration between frontend and backend, consistent architecture throughout the application stack, and efficient development cycles. Whether building from scratch or modernizing legacy systems, the focus is always on maintainable, production-ready code.

Building SaaS applications requires careful architectural decisions around multi-tenancy, data isolation, subscription management, and scalability. I design and implement SaaS platforms with tenant isolation strategies (database-per-tenant or schema-per-tenant), subscription and billing integration, role-based access control at scale, and API rate limiting and usage tracking.

The result is SaaS platforms that can onboard new customers seamlessly, scale with demand, maintain strict data isolation, and provide the infrastructure for sustainable recurring revenue business models.

Modern web applications benefit from cloud infrastructure for scalability, reliability, and global reach. I build cloud-native applications leveraging Azure App Services, Azure SQL Database, Azure Functions for serverless operations, Azure Storage and CDN for media and static assets, and Azure DevOps for CI/CD pipelines.

This cloud-first approach enables automatic scaling under load, geographic distribution for low latency, cost-effective infrastructure management, and built-in disaster recovery and high availability. Applications are designed to take full advantage of cloud capabilities from day one.

Web application success depends on both performance and security. I implement comprehensive performance optimization including server-side caching strategies, database query optimization and indexing, frontend asset optimization and lazy loading, and API response time monitoring. Security measures include OWASP Top 10 mitigation, authentication and authorization best practices (OAuth 2.0, OpenID Connect), SQL injection and XSS prevention, and HTTPS/TLS configuration and certificate management.

The combination ensures web applications that load fast, stay secure, pass security audits, and provide excellent user experiences even under heavy load.
