About this gig
Is your web app slow or failing to convert users? Performance affects your SEO, your bounce rate, and whether people come back. I build full stack web apps that load fast, scale cleanly, and deliver results.
I'm Hammad, a full stack developer with 5+ years shipping production apps for startups, SaaS businesses, and agencies.
What I build:
- React.js SPAs with clean component architecture
- Next.js apps with SSR, SSG, and built-in API routes
- Astro.js sites for content-heavy, near-zero JS performance
- Full stack apps with Node.js or Nest.js and PostgreSQL or MongoDB
- REST API development and third-party integrations
- Responsive UI from Figma or your own references
Who I work with: Startups needing an MVP, SaaS teams, agencies, and e-commerce businesses.
Stack: React.js, Next.js, Astro.js, TypeScript, Node.js, Nest.js, Tailwind CSS, PostgreSQL, MongoDB, Git, Docker
Not sure which package fits? Message me and I'll get back to you within a few hours.

FAQ
What do I need to get started?
Please have a clear idea of your project goals, any design files (Figma/XD), and content (text/images) ready.
Which framework is best for my project?
For content sites & SEO, Astro.js is fastest. For web apps with interactivity, Next.js/React is ideal. I will advise you on the best choice.
Do you provide hosting and deployment?
I can assist with deployment to platforms like Vercel or Netlify, but the hosting subscription fee is handled by the client.
Will the website be mobile-friendly?
Absolutely! Every project is developed with a mobile-first, fully responsive approach.
Do you work with existing websites or code?
Yes, I can refactor, update, or add new features to your existing React, Next.js, or Astro codebase.
What's included in a "revision"?
A revision round allows you to request a set of changes. Major changes or new features after completion may incur an additional cost.
Do you offer ongoing maintenance?
Yes, I offer dedicated maintenance and support packages after project delivery. Let's discuss your needs.
Can you integrate a database?
Yes, database integration (e.g., for user logins or dynamic content) is available in the Premium package.
