My Portfolio
FAQ
Do I need to provide the design or wireframes?
If you have a design (Figma, Adobe XD, or an example website), that's perfect. If not, don't worry! I focus heavily on frontend user experience and can propose a clean, modern layout tailored to your brand.
Which databases do you use for backend projects?
I primarily work with Supabase and PostgreSQL for real-time synchronization, secure data handling, and seamless integration with FastAPI backends.
What tools do you use for styling and ensuring fast loading times?
I use Tailwind CSS for highly optimized, modern, and fully responsive styling. Combined with Astro or Next.js, this ensures excellent SEO and lightning-fast loading speeds for your website.
