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.


PLEASE CONTACT ME BEFORE ORDERING Every project is unique. Let's discuss your specifications to ensure I am the perfect fit for your vision.


Let's build something exceptional. Louis | Studio SIT
