I will develop a secure saas web application


About this gig
You have a vision for a SaaS or a Web App, but you lack the technical partner to execute it properly. Most freelancers will just "make it work." I engineer it to scale.
I am Louis, an Engineering Student & Fullstack Developer, founder of Studio SIT. My mission is to bridge the gap between complex engineering and agile startup development.
Why choose Studio SIT? Unlike generic agencies, I bring academic rigor and a security-first mindset to your project.
- Scalable Architecture: Built on Next.js 14, ready to handle 0 to 100k+ users.
- Security by Design: OWASP standards, secure authentication, and protected APIs.
- Clean Code: Modular, typed (TypeScript), and documented. Easy for any dev to take over later.
️ My Tech Stack (The Modern Standard):
- Frontend: React.js, Next.js 14 (App Router), Tailwind CSS, Framer Motion.
- Backend: Node.js, Server Actions, API Routes.
- Database: Supabase, Firebase, MongoDB.
- Auth & Payments: Clerk/NextAuth, Stripe Subscription handling.
