XpanSieve Solutions is a digital agency and product studio focused on building practical software systems, web applications, and technical solutions.
I build scalable, secure backend systems that power modern applications. From database architecture to API design, authentication systems to data processing pipelines, my backend solutions are designed for reliability, performance, and long-term maintainability.
Every backend system I develop follows best practices for security, scalability, and clean code architecture. Whether it's a simple CRUD application or a complex data-driven platform, I ensure your backend can handle growth while remaining easy to maintain and extend.
Efficient PostgreSQL schemas with proper relationships, indexes, and data integrity constraints.
Node.js and Python backends with clean, testable code and proper error handling.
My backend development services cover the full spectrum of server-side requirements for modern applications.
I leverage modern, battle-tested technologies to build backend systems that are both powerful and maintainable. My primary stack includes Node.js, Python, PostgreSQL, and Supabase for rapid development without sacrificing quality.
From user authentication with JWT tokens to role-based access control, from database migrations to background job processing, I handle all aspects of backend development with attention to security and performance.
I primarily work with PostgreSQL for relational data and Supabase for real-time features. I also have experience with MongoDB for document-based storage and Redis for caching and session management.
I implement secure authentication using JWT tokens, OAuth2 for social logins, and industry-standard password hashing. For projects using Supabase, I leverage their built-in authentication system with Row Level Security for fine-grained access control.
Yes, I can integrate with existing databases and gradually improve schema design. I use database migrations to safely evolve your data structure without losing existing data or causing downtime.
I follow OWASP security guidelines, implement input validation, use parameterized queries to prevent SQL injection, and apply proper access controls. All sensitive data is encrypted, and I use HTTPS for all communications.
