FAQ
Do you only do backend or can you handle the full project?
I handle both. My core expertise is backend/API development but I also deliver complete full-stack solutions using Angular and React.js on the frontend. If you need a complete product, just message me and I'll put together the right package.
I have an existing system - can you add new APIs or integrations to it?
Absolutely. This is something I do regularly. I'll review your existing codebase, understand the architecture, and integrate cleanly without breaking what's already working.
Can you handle healthcare or telemedicine projects?
Yes - this is one of my strongest areas. I have hands-on experience delivering EMR systems and telemedicine platforms. I understand the domain, the data sensitivity, and the integrations these systems require.
What if my project is larger than the listed packages?
No problem. Message me with your requirements and I'll create a custom offer tailored to your exact scope, timeline, and budget.
Do you provide documentation with the API?
Yes. All deliverables include proper API documentation so your frontend team or future developers can work with it without confusion.
How do you handle communication during the project?
I provide regular updates throughout the project. Before starting I confirm full scope, during development I share progress, and I'm always reachable for questions. You'll never be left wondering what's happening with your project.
Do you work on school or college assignments?
No. I exclusively work on real business projects.
