About this service

Summary

I build scalable, end-to-end web applications using modern full-stack technologies including React, Node.js, NestJS, and MongoDB. From frontend design to backend logic and secure deployment, I deliver production-ready platforms optimized for performance, flexibility, and growth.

Process

1. Discovery & Planning

We’ll define your business goals, core features, user flow, and technical scope. I’ll suggest the right stack & architecture.

2. UI/UX Design or Integration

Work with provided designs or create a basic UI layout using components. Ensure responsiveness and performance from the ground up.

3. Backend Development

Setup NestJS project with database, user auth, role management, APIs, error handling, and integrations.

4. Frontend Development

Connect APIs to React frontend, build routes, state management (Redux/Context), and dynamic components.

5. Testing & QA

Test backend APIs and frontend flows for bugs, performance, responsiveness, and cross-browser compatibility.

6. Deployment & Optimization

Setup Docker or CI/CD workflow and deploy to cloud platforms (AWS, Vercel, or custom). Configure domains and environment variables.

7. Final Delivery & Support

Code handover with documentation and walk-through. I’ll be available for bug fixes, feature additions, or scaling needs.

FAQs

What types of apps can you build?
I’ve built SaaS platforms, booking systems, CRMs, dashboards, e-learning apps, and healthcare systems — from startup MVPs to enterprise tools.
Do I need to provide a design?
Not required. I can work from wireframes, references, or Figma files—or build the UI based on your idea.
Will it be mobile-responsive?
Yes. Every app is built mobile-first and tested across devices.
Can you integrate third-party services?
Absolutely — Stripe, Firebase, Twilio, SendGrid, PayPal, Google APIs, and more.
Is hosting included?
I’ll guide and set up deployment for your preferred platform — AWS, Vercel, DigitalOcean, GCP, or others.
Will you write tests?
Yes. I write backend and frontend tests using Jest, Playwright, or Supertest based on project size.
Do you use Docker or CI/CD?
Yes. I can containerize the project and set up automated builds/deployments via GitHub Actions or GitLab CI/CD.
Is the app SEO-friendly?
If SEO is a requirement, I’ll implement SSR with Next.js or server-side rendering techniques to improve visibility.
Can I request post-launch support?
Definitely. I offer hourly or retainer-based support for ongoing updates or scaling needs.
Will I own the source code?
Yes — 100%. You’ll receive the complete source code, documentation, and deployment access.
