FAQ
What technologies do you use for fullstack development?
I specialize in using Angular or React for the frontend, Node.js with Express or ASP.NET Core for the backend, SQL Server, PostgreSQL, MySQL, Mongo for the database, and tools like Jest, Cypress, and Jasmine for testing. I also offer deployment on platforms like Azure, Vercel, and Render.
Can I choose the tech stack I prefer?
Yes! You can specify your preferred tech stack (React/Angular, Node/ASP.NET, etc.), or I can recommend the best stack based on your project goals.
Will the project be mobile responsive?
Absolutely. Every application I build is fully responsive and optimized for desktop, tablet, and mobile devices.
Do you provide testing for the application?
Yes! Unlike many others, I include unit and end-to-end testing using tools like Jest, Cypress, Jasmine and xUnit, especially in the Premium package. This ensures your application runs reliably and bug-free.
Will I be able to manage the app myself after delivery?
Definitely. I write clean, well-documented code and can provide a walkthrough or README to help you or your team manage the project confidently.
Can you integrate third-party APIs or external services?
Yes, I can integrate third-party APIs such as payment gateways, maps, email services, and more — just let me know your requirements.
Do you provide deployment services?
Yes, I handle complete deployment for all packages. Basic includes deployment to render, vercel, netlify, github pages. For the Standard and Premium packages, I can deploy your app to Your domain, VPS, or any preferred platform, and configure CI/CD pipelines in the Premium tier.
What if I’m not sure what I need yet?
No worries — send me a message! I’ll help you define your requirements and suggest the best solution based on your goals and budget.
