About me

I make websites from the draft to going live, from the layout to the code. In the videos, who I am and what I build; in the cards, what I deliver and how we work together.

What I do

I put the layout together and write the site's code myself.

  • A layout put together for your business, instead of an off-the-shelf theme.

  • A site that opens fast on 4G, with Core Web Vitals measured.

  • Semantic HTML and structured data, so Google can read the site.

Tell me about your project
Who I am. A roughly 23-second animation styled like a video game. A "press start" screen opens on the name João Vitor Carmassi. The character select shows his photo, the class "front-end developer" and the origin "são paulo, 2004". A map over an aerial photo of Pedra do Baú pins his base in São Bento do Sapucaí, SP, and a route runs to a globe: "from the mountains to the world", "100% remote". Stat bars show his languages: Portuguese native, English C1 and Spanish B2. The inventory holds hiking, motorcycle trips, music, games, movies and, equipped, code. It ends on "progress saved", the signature "joão." and github.com/joao-carmassi.
What I build. A roughly 23-second animation built around one browser window. A hand-drawn sketch snaps into the window, reading "from sketch to live". A TypeScript component types itself out and the stack's logos fly out of it: Next.js, React, TypeScript, Tailwind, Astro, GSAP, React Query, Zustand and Git. The window moves through four kinds of project: business websites (Refúgio da Pedra, Dr. Jean Almeida), e-commerce (Loja do VRF), interactive maps (São Bento tourist map) and SaaS and dashboards (Quotation Factory, Higgx). Then a GSAP easing curve draws next to a Prisma UI button, and under "SEO from day one" a search result climbs to first place while four Lighthouse scores fill to 100. It ends on João Carmassi, front-end developer, and "tell me about your project".

How I work

Scope agreed up front, a live link and SEO from day one.

  • I research the words your customer types in your industry.

  • I audit with Google's tools and fix what they point out.

  • After launch, tweaks and maintenance stay with me.
