FAQ
Should I contact you before placing an order?
Yes, absolutely. Software architecture and features vary greatly in complexity. Contacting me first allows us to discuss your technical requirements, choose the right tech stack (Node.js/NestJS/React), and ensure an accurate timeline and pricing for your project.
Will the code be clean and well-documented?
Yes. I strictly follow Clean Architecture principles and TypeScript type safety. Every function and module will include detailed code comments, and if required, I will provide full REST API documentation using Swagger/OpenAPI for seamless integration.
Can you deploy the application to my cloud infrastructure?
Yes, I can handle deployment. Whether you are using Supabase, Docker, or managing production microservices on Kubernetes clusters, I can ensure a smooth deployment process with high availability and proper environment configuration.
Do you provide post-delivery support or bug fixes?
Yes, I provide a standard support window after delivery to ensure everything runs smoothly on your end. If you encounter any bugs or performance issues related to the agreed scope, I will resolve them promptly.
