Service details

I will deliver a complete, high-performance, and secure backend system or API to power your mobile or web application. You will receive a robust technical foundation built using either Spring Boot or ASPDotNet Core, chosen based on your specific project requirements, performance needs, and existing ecosystem. My approach focuses on creating scalable, maintainable, and reliable architectures from the ground up.

For the core service layer, I design and implement a suite of secure RESTful APIs with comprehensive documentation. This documentation includes clear endpoint definitions, request-response examples, and authentication protocols to ensure your frontend team can integrate seamlessly and efficiently. The API layer is built with best practices in mind, including proper error handling, logging, and validation to ensure system stability.

Your data layer will be configured using either a robust SQL database, such as PostgreSQL or MySQL, for structured, transactional data, or MongoDB for flexible, document-based storage needs. The database design will be optimized for your application's specific query patterns, with appropriate indexing and relationships to ensure speed and data integrity.

Every line of code is written with long-term maintainability in mind. I adhere to clean code principles, design patterns like repository and service layers, and write unit and integration tests to ensure reliability. The final deliverable is deployment-ready code, structured for modern CI/CD pipelines. I can provide guidance on deploying to cloud platforms like Microsoft Azure or AWS, ensuring your application is built for scalability, security, and performance from day one.

My goal is to transform your functional requirements into a polished, production-ready backend. This includes setting up authentication and authorization, automating key workflows, and building monitoring hooks. By handling the complex infrastructure, I enable you to focus entirely on your core product logic and user experience, accelerating your time to market with a dependable and scalable technical backend.

Yes, each package includes post-delivery support for bug fixes and clarifications during the revision period. Extended support can be arranged separately.

Can you work with existing codebases or APIs?

Absolutely. I can extend, refactor, or integrate with your current backend, mobile app (Flutter), or third-party services.

What if my project doesn't fit your packages?

I offer custom quotes. Contact me with your requirements, and I'll provide a tailored scope, timeline, and price.

How do you ensure code quality and security?
