My Portfolio
FAQ
What type of web application do you need (e.g., SaaS, eCommerce, Admin Panel, Portfolio)?
I can build any type of custom web application to fit your needs—whether it's a SaaS platform, eCommerce store, portfolio site, CRM, dashboard, or admin panel. Just share your vision, and I’ll bring it to life with a scalable and responsive solution.
Do you already have a design or wireframe, or should I create one from scratch?
I'm flexible! If you already have a design (e.g., Figma, XD, or Sketch), I can implement it exactly. If not, I can help design a clean, modern UI using best practices with Tailwind CSS and component-based architecture.
Do you require user authentication (login/signup with email, Google, etc.)?
Yes, I can implement secure authentication systems using JWT, OAuth, Firebase Auth, or custom login logic. Whether it's email/password or social login, I've got it covered.
Do you want me to deploy the app for you (Vercel, Netlify, AWS, GCP)?
Absolutely. I can handle full deployment on platforms like Vercel, Netlify, AWS, or GCP. Your app will be fully live, secure (with HTTPS), and optimized for performance.
Which features are must-haves for your project (CRUD, payments, notifications, chat, etc.)?
Tell me the features you need—CRUD operations, payment gateways (Stripe, Razorpay), real-time chat, push notifications, analytics, file uploads, and more. I’ll prioritize and integrate them seamlessly.
Is SEO important for your project? Should I optimize your site for search engines?
Yes! I offer SEO optimization services including meta tags, Open Graph data, structured schema, and performance improvements to help your site rank better and load faster.
Do you have any preferred stack or are you open to recommendations?
If you have a specific tech stack in mind, I’m happy to follow it. Otherwise, I’ll suggest the best stack based on your goals—MERN, Next.js, Firebase, PostgreSQL, or others to ensure scalability and speed.
Do you need ongoing maintenance or support after delivery?
Yes, I offer maintenance and post-launch support packages. Whether it's updates, bug fixes, or scaling features, I’m available to ensure your app runs smoothly long-term.
Are there any reference websites or apps you like?
Yes, if you have any reference sites or apps you admire, please share them! It helps me understand your taste in design, UX, and feature expectations, ensuring better results.

Overall my project was delivered as expected and I am happy with the delivery. I just wish he spent time reading my requirements carefully and making sure that everything was done according to those before submitting. That would've saved us a lot of back and forth because all of the revisions to the delivery were already in my requirements document.
