About this gig
Is a slow, generic site costing you customers? Your vision is unique; your build should be too.
I build custom, production-ready web apps using Next.js, React, and Tailwind CSS. I skip templates to provide performance and security that off-the-shelf solutions can't match.
What You Get:
- Speed: 80+ Lighthouse scores for higher SEO rankings.
- Responsive UX: Seamless experience on mobile, tablet, and desktop.
- Clean Code: Scalable React/TypeScript architecture.
- Dynamic Features: Secure Firebase/Supabase integration.
Security-First Mindset:
- Data Protection: Custom Firebase Security Rules & Row Level Security (RLS).
- Auth: Secure Social OAuth or Email/Password with JWT.
- Environment Safety: Strict .env management to protect API credentials.
Professional Communication:
- Roadmap Alignment: We consult on your goals before a single line of code is written.
- Milestone Updates: Regular progress check-ins so you're always in the loop.
- Post-Launch Support: Clear walkthroughs of your admin panel and database.
I use an AI-augmented workflow to handle boilerplate, allowing me to focus 100% on your custom logic and UI polish.
Message me to discuss your roadmap before ordering!

FAQ
Why do you use Next.js and Tailwind?
These are standard, modern technologies used by companies like Netflix and Nike. Together, they provide unparalleled performance, incredible SEO, and a completely customized visual experience that is significantly faster and more secure than generic WordPress themes.
Is this just "copy-pasted" AI code?
Absolutely not. I am a full-stack developer. I use AI to accelerate the initial setup (generating the standard components, basic styling). I manually architecture every line of your logic, implement complex security measures, and write the critical code that makes your site professional and unique.
Can you add custom features not possible with templates?
Yes. Since your site is a custom application built from the ground up, I have complete control. We can integrate any API, custom interactive component, or backend logic your business requires.
How long will my project take to complete?
Timeline depends on complexity. A 1-page SEO landing page typically takes 3–5 days, while a full Multi-page/E-commerce site takes 10–14 days. For "Surgical Fixes," I often deliver within 24–48 hours. Message me for a custom roadmap!
Do you offer support after the project is delivered?
Yes! I provide 30 days of post-launch technical support to ensure everything runs smoothly. I also include a video walkthrough of your Firebase/Admin panel so you feel confident managing your content and users.
My project involves sensitive data. Is it secure?
Absolutely. I implement Security-First Architecture using Firebase/Supabase Security Rules (RLS) and JWT validation. This ensures only authorized users can access their data, protecting your business from common vulnerabilities.
Do I need to buy hosting or a database separately?
I primarily use Nelify/Vercel for hosting and Firebase/Supabase for data. These platforms offer generous free tiers that are perfect for most startups. I will guide you through the 5-minute setup process to ensure you own your infrastructure.
